ba361cb3d4 sh_eth: r8a7790: Handle the RFE (Receive FIFO overflow Error) interrupt
The RFE interrupt is enabled for the r8a7790 but isn't handled,
resulting in the interrupts core noticing unhandled interrupts, and
eventually disabling the ethernet IRQ.

Fix it by adding RFE to the bitmask of error interrupts to be handled
for r8a7790.

Jeff Kirsher says:

====================
This series contains updates to ixgbe and pci.

The first patch for ixgbe from Greg Rose is the second submission.  The
first submission of "ixgbe: Retain VLAN filtering in promiscuous + VT
mode" had a typo, which Joe Perches pointed out and is fixed in this
submission.

Alex updates the ixgbe driver to use the generic helper pci_vfs_assigned
instead of the driver specific function ixgbe_vfs_are_assigned.

Don Skidmore provides 4 patches for ixgbe, the first being a fix for
flow control ethtool reporting.  Originally ixgbe_device_supports_autoneg_fc()
was expected to be called by only copper devices, which lead to false
information being displayed via ethtool.  Two other patches add support
for fixed fiber for SFP+ devices and the addition of a quad-port x520
adapter.  The last patch simply bumps the driver version.

Emil Tantilov provides 3 fixes for ixgbe, two of which resolve
semaphore lock issues.  The third fix resolves several issues in the
previous implementation of the SFF data dumps of SFP+ modules.

The remaining ixgbe and pci patches are from Jacob Keller.  The pci
patches exposes bus speed, link speed and bus width so that drivers
can take advantage of this information.  In addition, adds a pci function
which obtains minimum link width and speed.  Jacob also provides the
ixgbe patch to incorporate the pci function. He provides a patch that
fixes a lockdep issue created due to ixgbe_ptp_stop always running
cancel_work_sync even if the work item had not been created properly with
INIT_WORK. This issue was found and reported by Stephen Hemminger.

674c18b2ed ixgbe: clear semaphore bits on timeouts
This patch changes the error code path in ixgbe_acquire_swfw_sync() to deal
with cases where acquiring SW semaphore times out.

In cases where the SW/FW semaphore bits were set (i.e. due to a crash) the
driver will hang on load. With this patch the driver will clear
the stuck bits if the semaphore was not acquired in the allotted time.

8fecf67c7e ixgbe: fix lockdep annotation issue for ptp's work item
This patch fixes a lockdep issue created due to ixgbe_ptp_stop always running
cancel_work_sync even if the work item had not been created properly with
INIT_WORK. This is caused because ixgbe_ptp_stop did not check to actually
ensure PTP was running first. The new implementation introduces a state in the
&adapter->state field which is used to indicate that PTP is running. (This
replaces the IXGBE_FLAG2_PTP_ENABLED field). This state will use the atomic
set_bit, test_bit, and test_and_clear_bit functions. ixgbe_ptp_stop will check
to ensure that PTP was enabled, (and if not, it will not attempt to do any
cleanup work from ixgbe_ptp_init). This resolves the lockdep annotation warning
found by Stephen Hemminger

e027d1aec4 ixgbe: call pcie_get_mimimum_link to check if device has enough bandwidth
This patch uses the new pcie_get_minimum_link function to perform a check to
ensure that the adapter is hooked into a slot which is capable of providing the
necessary bandwidth. This check supersedes the original method which only
checked the current pci device. The new method is capable of determining the
minimum speed and link of an entire PCI chain.

81377c8d35 PCI: Add function to obtain minimum link width and speed
A PCI Express device can potentially report a link width and speed which it will
not properly fulfill due to being plugged into a slower link higher in the
chain. This function walks up the PCI bus chain and calculates the minimum link
width and speed of this entire chain. This can be useful to enable a device to
determine if it has enough bandwidth for optimum functionality.

a4b6fc6bc6 ixgbe: fix SFF data dumps of SFP+ modules
This patch fixes several issues with the previous implementation of the
SFF data dump of SFP+ modules:

- removed the __IXGBE_READ_I2C flag - I2C access locking is handled in the
  HW specific routines

- fixed the read loop to read data from ee->offset to ee->len

- the reads fail if __IXGBE_IN_SFP_INIT is set in the process - this is
  needed because on some HW I2C operations can take long time and disrupt
  the SFP and link detection process

3dcc2f4142 ixgbe: fix semaphore lock for I2C read/writes on 82598
ixgbe_read/write_i2c_phy_82598() does not hold the SWFW_SYNC
semaphore for the entire function. Instead the lock is held only
during the phy.ops.read/write_reg operations. As result when the
function is being called simultaneously the I2C read/writes can
be corrupted.

The following patch introduces the SWFW_SYNC semaphore for the
entire ixgbe_read/write_i2c_phy_82598() function. To accomplish
this I had to create 2 separate functions:

ixgbe_read_phy_reg_mdi()
ixgbe_write_phy_reg_mdi()

Those functions are identical to ixgbe_read/write_phy_reg_generic()
sans the locking, and can be used in ixgbe_read/write_i2c_phy_82598()
with the SWFW_SYNC semaphore being held.

69e12d887c Merge branch 'phys_port'
Jiri Pirko says:

====================
This patchset is based on patch by Narendra_K@Dell.com
Once device which can change phys port id during its lifetime adopts this,
NETDEV_CHANGEPHYSPORTID event will be added and driver will call
call_netdevice_notifiers(NETDEV_NETDEV_CHANGEPHYSPORTID, dev) to propagate
the change to userspace.

v1->v2: as suggested by Ben, handle -EOPNOTSUPP in rtnl code (wrapped up ndo call)
v2->v3: adjusted patch 1 commit message
v3->v4: used "%phN" for sysfs printf as suggested by DaveM
        added igb/igbvf implementation as requested by Or Gerlitz
v4->v5: used prandom_u32 to generate id in igb_probe
        removed duplicate code in ibgvf_probe
        pushed dev_err string into one line in igbvf_refresh_ppid
v5->v6: use uuid_le_gen for generating 16-byte phys port id for igb/igbvf
	as suggested by BenH

1) Why do we need this, and why do existing facilities fail to provide
   a way to accomplish this?

Currenty there's very hard to tell if two netdevs are using the same physical
port. For sr-iov this can be get by sysfs. For other mechanisms, like NPAR
there's very hard to do it (one must learn it from NIC BIOS). But even for
sr-iov there's no way to say if two netdevs are using the same phys port when
these are passed through to virtual guests.

This patchset provides the generic way of letting this information know to
userspace. This info can be used by apps like NetworkManager, teamd, Wicked,
ovs daemon, etc, to do smarter bonding decisions.

2) Why is the physical port ID defined as a 32 byte opaque cookie?
   What formats and layouts need to be accomodated, and which
   influenced the design of the ID?

For user to distinguish if two netdevs are using the same port, he only needs
to compare their phys port ids. Nothing else is needed. This id has no
structure for security reasons. VF should not know anything about PF.

3) Are IDs globally unique?  Why or why not?  If IDs should be
   globally unique, but only in certain cases, what exactly are those
   cases.

Most of the time only uniqueness needed is in scope of single machine.
There might be case when the id should be unique between couple of machines
in virtualization environment. Given that for example for igb/igbvf 16B uuid
is used, there is no problem for this case as well. But each driver can
implement this differently focusing the hw capabilities and needs.

The macros used for the various fields of the RX and TX descriptions

However, in order to support big endian, we'll have to use the "swap
descriptors" features of the hardware, which swaps every byte within
each 64 bits word of the descriptors. This requires a separate
definition of the RX and TX descriptor structures for little and big
endian, as is done in the mv643xx_eth. Those macros can therefore no

c1459356d9 tg3: Remove incorrect switch to aux power
During probe, the driver is incorrectly switching the power to Vaux on
the 5717 and later devices. At this point, we are in D0 state and
drawing maximum power. We also definitely have Vmain available. It
doesn't make sense to switch to Vaux since it has a lesser maximum power
draw and we might go over the limit. On a new system, we observe that
not all ports are recognized in some of the slots with this call in
place.

b54345ea32 cnic: Simplify cnic_release().
Since unregister_netdevice_notifier() will replay the NETDEV_DOWN and
NETDEV_UNREGISTER_EVENTS, the cnic_dev_list will be cleaned up automatically.
The loop to cleanup the cnic_dev_list can be removed in cnic_release().

415fb87da8 cnic: Simplify netdev events handling.
After this earlier commit to simplify probing:

    commit 4bd9b0fffb
    cnic, bnx2x, bnx2: Simplify cnic probing.

we can now reliably receive netdev events and we can simplify the handling
of these events.  We now remove the logic that tries to handle missed
NETDEV_REGISTER events.

This change will allow cleanup to be simplified in the next patch.  We can
now rely on the play back of netdev events during
unregister_netdevice_notifier() to cleanup the structures.

fe6f700d6c net/mlx4_core: Respond to operation request by firmware
This commit adds new firmware command and new firmware event.  The firmware
raises the MLX4_EVENT_TYPE_OP_REQUIRED event in order to signal the driver it
needs to perform an administrative operation throughout the MLX4_CMD_GET_OP_REQ
command. At the moment the supported operation is adding/removing multicast
entries which are used by the firmware for handling NCSI traffic in B0
steering mode.

Also, had to swap the order of mlx4_init_mcg_table() and
mlx4_init_eq_table() to make sure that driver will get events only after
resources are initialized to handle it.

2d4b646613 net/mlx4_en: Fix BlueFlame race
Fix a race between BlueFlame flow and stamping in post send flow.
Example:
	SW: Build WQE 0 on the TX buffer, except the ownership bit
	SW: Set ownership for WQE 0 on the TX buffer
	SW: Ring doorbell for WQE 0
	SW: Build WQE 1 on the TX buffer, except the ownership bit
	SW: Set ownership for WQE 1 on the TX buffer
	HW: Read WQE 0 and then WQE 1, before doorbell was rung/BF was done for WQE 1
	HW: Produce CQEs for WQE 0 and WQE 1
	SW: Process the CQEs, and stamp WQE 0 and WQE 1 accordingly (on the TX buffer)
	SW: Copy WQE 1 from the TX buffer to the BF register - ALREADY STAMPED!
	HW: CQE error with index 0xFFFF  - the BF WQE's control segment is STAMPED,
		so the BF index is 0xFFFF. Error: Invalid Opcode.
As a result QP enters the error state and no traffic can be sent.

Solution:
When stamping - do not stamp last completed wqe.

34d073fcd3 Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next
Jeff Kirsher says:

====================
This series contains updates to e100 and e1000e.

The e100 patch from Andy simply updates the netif_printk() to use
%*ph to dump small buffers.

The changes to e1000e include a fix from Dean Nelson to resolve a
issue where a pci_clear_master() was accidentally dropped during a
conflict resolution. Wei Young provides 2 patches, one removes an
assignment of the default ring size because it was a duplicate. The
second changes the packet split receive structure to use
PS_PAGE_BUFFERS macro for the length so that problems won't occur
when the length is changed.

The remaining patches for e1000e are from Bruce Allan, where he
provides a number of fixes and updates for I218.  In addition, a
fix for 82583 which can disappear off the PCIe bus, to resolve this,
disable ASPM L1.  Bruce also provides a fix to a previous commit
(commit e60b22c5b7 e1000e: fix accessing to suspended device) so that
devices are only taken out of runtime power management for those
ethtool operations that must access device registers.
