3efa9ed260 ixgbe: Fix issues with EEPROM access
There are two problems with EEPROM access. One is that it needs to
hold the semaphore until the entire response is read or else the
response can be corrupted by other firmware accesses. The second
problem is that acquiring and releasing the semaphore is slow, so
it should be taken and released once when multiple EEPROM accesses
will be done.

Both of these issues can be solved by adding a new function,
ixgbe_hic_unlocked, to issue firmware commands that will assume
that the caller has acquired the needed semaphore.

aeb4c73100 ixgbe: Fix incorrect bitwise operations of PTP Rx timestamp flags
Rx timestamp does not work on 82599 and X540 because bitwise operation

b19cf6eea9 ixgbevf: fix AER error handling
Make sure that we free the IRQs in ixgbevf_io_error_detected() when
responding to an PCIe AER error and also restore them when the
interface recovers from it.

Previously it was possible to trigger BUG_ON() check in free_msix_irqs()
in the case where we call ixgbevf_remove() after a failed recovery from
AER error because the interrupts were not freed.

Also moved the down and free functions into ixgbevf_close_suspend()
same as with ixgbe.

a9d2d53a78 ixgbe: test for trust in macvlan adjustments for VF
There are two methods for setting mac addresses in a Macvlan, that
differentiate themselves in the function macvlan_set_mac_Address.
If the macvlan mode is passthru, then we use the dev_set_mac_address
method, otherwise we use the dev_uc api via macvlan_sync_addresses.
The latter method (which would stem from using any non-passthru mode,
like bridge, or vepa), calls down into the driver in a path that terminates
in ixgbevf_set_uc_addr_vf, which sends a IXGBE_VF_SET_MACVLAN message,
which causes the pf to spawn the noted error message.  This occurs because
it appears that the guest is trying to delete the mac address of the macvlan
before adding another.

The other path in macvlan_set_mac_address uses dev_set_mac_address, which
calls into ixgbevf_set_mac which uses the IXGBE_VF_SET_MAC_ADDR to the
pf to set the macvlan mac address.

The discrepancy here is in the handlers.  The handler function for
IXGBE_VF_SET_MAC_ADDR (ixgbe_set_vf_mac_addr) has a check for
the vfinfo[].trusted bit to allow the operation if the vf is trusted.
In comparison, the IXGBE_VF_SET_MACVLAN message handler
(ixgbe_set_vf_macvlan_msg) has no such check of the trusted bit.

2dad7b2775 ixgbevf: handle race between close and suspend on shutdown
When an interface is part of a namespace it is possible that
ixgbevf_close() may be called while ixgbevf_suspend() is running
which ends up in a double free WARN and/or a BUG in free_msi_irqs()

To handle this situation we extend the rtnl_lock() to protect the
call to netif_device_detach() and check for !netif_device_present()
to avoid entering close while in suspend.

Also added rtnl locks to ixgbevf_queue_reset_subtask().

096de2f83e benet: stricter vxlan offloading check in be_features_check
When VXLAN offloading is enabled, be_features_check() tries to check if
an encapsulated packet is indeed a VXLAN packet. The check is not strict
enough, and considers any UDP-encapsulated ethernet frame with a 8-byte
tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE
have a 8-byte header, so they get through this check.

Force the UDP destination port to be the one that has been offloaded to
hardware.

Without this, GENEVE-encapsulated packets can end up having an incorrect
checksum when both a GENEVE and a VXLAN (offloaded) tunnel are
configured.

This is similar to commit a547224dce ("mlx4e: Do not attempt to
offload VXLAN ports that are unrecognized").

7d0cc6edcc IB/mlx5: Add MR cache for large UMR regions
In this change we turn mlx5_ib_update_mtt() into generic
mlx5_ib_update_xlt() to perfrom HCA translation table modifiactions
supporting both atomic and process contexts and not limited by number
of modified entries.
Using this function we increase preallocated MRs up to 16GB.

3161625589 IB/mlx5: Refactor UMR post send format
* Update struct mlx5_wqe_umr_ctrl_seg.
* Currenlty UMR send_flags aim only certain use cases: enabled/disable
  cached MR, modifying XLT for ODP. By making flags independent make UMR
  more flexible allowing arbitrary manipulations.
* Since different UMR formats have different entry sizes UMR request
  should receive exact size of translation table update instead of
  number of entries. Rename field npages to xlt_size in struct mlx5_umr_wr
  and update relevant code accordingly.
* Add support of length64 bit.

31b95c9bdc net: stmmac: remove unused duplicate property snps,axi_all
For core revision 3.x Address-Aligned Beats is available in two registers.
The DT property snps,aal was created for AAL in the DMA bus register,
which is a read/write bit.
The DT property snps,axi_all was created for AXI_AAL in the AXI bus mode
register, which is a read only bit that reflects the value of AAL in the
DMA bus register.

Since the value of snps,axi_all is never used in the driver,
and since the property was created for a bit that is read only,
it should be safe to remove the property.

e3eef7ee02 qede: Postpone reallocation until NAPI end
During Rx flow driver allocates a replacement buffer each time
it consumes an Rx buffer. Failing to do so, it would consume the
currently processed buffer and re-post it on the ring.
As a result, the Rx ring is always completely full [from driver POV].

We now allow the Rx ring to shorten by doing the re-allocations
at the end of the NAPI run. The only limitation is that we still want to
make sure each time we reallocate that we'd still have sufficient
elements in the Rx ring to guarantee that FW would be able to post
additional data and trigger an interrupt.

e1d32acbcb qed*: Change maximal number of queues
Today qede requests contexts that would suffice for 64 'whole'
combined queues [192 meant for 64 rx, tx and xdp tx queues],
but registers netdev and limits the number of queues based on
information received by qed. In turn, qed doesn't take context
into account when informing qede how many queues it can support.

This would lead to a configuration problem in case user tries
configuring >64 combined queues to interface [or >96 in case
xdp isn't enabled]. Since we don't have a mangement firware
that actually provides so many interrupt lines to a single
device we're currently safe but that's about to change soon.

The new maximum is hence changed:
  - For RoCE devices, the limit would remain 64.
  - For non-RoCE devices, the limit might be higher [depending
    on the actual configuration of the device].
qed would start enforcing that limit in both scenarios.

alignment to access registers.  This change contains the following:
 1. Function _rtl8821ae_dbi_read() is used to read one byte from DBI,
    thus it should use rtl_read_byte().
 2. Register 0x4C7 of 8192ee is single byte.

d96324703f rt2x00: merge agc and vco works with link tuner
We need to perform different actions (AGC and VCO calibrations and VGC
tuning) periodically at different intervals. We don't need separate
works for those, we can use link tuner work and just check for proper
interval on it.

This fixes performing AGC and VCO calibration when scanning on STA
mode. We need to be on-channel to perform those calibrations.

8f03a7c6e7 rt2800: set MAX_PSDU len according to remote STAs capabilities
MAX_LEN_CFG_MAX_PSDU specify maximum transmitted by HW AMPDU length
(0 - 8kB, 1 - 16kB, 2 - 32kB, 3 - 64kB). Set this option according to
remote stations capabilities (based on HT ampdu_factor). However limit
the value based our hardware TX capabilities as some chips can not send
more than 16kB (factor 1). Limit for all chips is currently 32kB
(factor 2), but perhaps for some chips this could be increased
to 64kB by setting drv_data->max_psdu to 3.

Since MAX_LEN_CFG_MAX_PSDU is global setting, on multi stations modes
(AP, IBSS, mesh) we limit according to less capable remote STA. We can
not set bigger value to speed up communication with some stations and
do not break communication with slow stations.

1fef293b8a orinoco: Use shash instead of ahash for MIC calculations
Eric Biggers pointed out that the orinoco driver pointed scatterlists

Fix it by switching from ahash to shash.  The result should be

ae3cf47645 iwlegacy: make il3945_mac_ops __ro_after_init
There's no need for this to be only __read_mostly, since
it's only written in a single way depending on the module
parameter, so that can be moved into the module's __init
function, and the ops can be __ro_after_init.

This is a little bit safer since it means the ops can't
be overwritten (accidentally or otherwise), which would
otherwise cause an arbitrary function or bad pointer to
be called.

d679fa1b3c ath10k: recal the txpower when removing interface
The txpower is being recalculated when adding interface to make sure
txpower won't overshoot the spec, and when removing the interface,
the txpower should again to be recalculated to restore the correct value
from the active interface list.

Following is one of the scenario
	vdev0 is created as STA and connected: txpower:23
	vdev1 is created as P2P_DEVICE for control interface: txpower:0
	vdev2 is created as p2p go/gc interface: txpower is 21

So the vdev2@txpower:21 will be set to firmware when vdev2 is created.
When we tear down the vdev2, the txpower needs to be recalculated to
re-set it to vdev0@txpower:23 as vdev0/vdev1 are the active interface.

	ath10k_pci mac vdev 0 peer create 8c:fd:f0:01:62:98
	ath10k_pci mac vdev_id 0 txpower 23
	... (adding interface)
	ath10k_pci mac vdev create 2 (add interface) type 1 subtype 3
	ath10k_pci mac vdev_id 2 txpower 21
	ath10k_pci mac txpower 21
	... (removing interface)
	ath10k_pci mac vdev 2 delete (remove interface)
	ath10k_pci vdev 1 txpower 0
	ath10k_pci vdev 0 txpower 23
	ath10k_pci mac txpower 23
