0fa74a4be4 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
	drivers/net/ethernet/emulex/benet/be_main.c
	net/core/sysctl_net_core.c
	net/ipv4/inet_diag.c

The be_main.c conflict resolution was really tricky.  The conflict
hunks generated by GIT were very unhelpful, to say the least.  It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().

So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged.  And this worked beautifully.

The inet_diag.c and sysctl_net_core.c conflicts were simple
overlapping changes, and were easily to resolve.

a8e0c246da bnx2x: fix encapsulation features on 57710/57711
E1x chips (57710, 57711(E)) have no support for encapsulation
offload. bnx2x incorrectly advertises the support as available.

Setting of those features is conditional on "!CHIP_IS_E1x(bp)", but
the bp struct is not initialized yet at this point and consequently
any chip passes the check.
The check must use the "chip_is_e1x" local variable instead to work
correctly.

da29370056 bnx2x: Force fundamental reset for EEH recovery
EEH recovery for bnx2x based adapters is not reliable on all Power
systems using the default hot reset, which can result in an

5f35227ea3 net: Generalize ndo_gso_check to ndo_features_check
GSO isn't the only offload feature with restrictions that
potentially can't be expressed with the current features mechanism.
Checksum is another although it's a general issue that could in
theory apply to anything. Even if it may be possible to
implement these restrictions in other ways, it can result in
duplicate code or inefficient per-packet behavior.

This generalizes ndo_gso_check so that drivers can remove any
features that don't make sense for a given packet, similar to
netif_skb_features(). It also converts existing driver
restrictions to the new format, completing the work that was
done to support tunnel protocols since the issues apply to
checksums as well.

By actually removing features from the set that are used to do
offloading, it solves another problem with the existing
interface. In these cases, GSO would run with the original set
of features and not do anything because it appears that
segmentation is not required.

02dc4025a0 bnx2x: Use correct fastpath version for VFs.
Our FW can support several fastpath HSI [for backward compatibility] but up
until now VFs were always configured to use latest fastpath HSI [although VF
driver might be older and use an older fastpath HSI].

For linux drivers, the differences are insignificant since driver never
utilized features that were overridden by the HSI change. But for VMs running
other operating systems this might be a problem.
In addition, eventually FW might change fastpath HSI in such a manner that
backward compatibility WILL break unless configured with proper version.

This patch fixes the issue for other operating system VMs, as well as lays
the ground work for forward compatibility in regard to the fastpath HSI.

892311f66f ethtool: Support for configurable RSS hash function
This patch extends the set/get_rxfh ethtool-options for getting or
setting the RSS hash function.

It modifies drivers implementation of set/get_rxfh accordingly.

This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.

User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.

Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

a345ce71e5 bnx2x: Prevent pci_disable_sriov with assigned VFs
Trying to disable sriov when VFs are assigned may lead to all kinds of problems.
This patch unifies the call in the driver to pci_disable_sriov() and prevents
them if some of the PF's child VFs are marked as assigned.

[Notice this is a bad scenario either way; User should not reach a point where
the OS tries to disable SRIOV when a VF is assigned - but currently there's no
way of preventing the user from doing so, and the ill-effect for the driver is
smaller this way]

0d8de80f5c bnx2x: Prevent IOV if no entries in CAM
It's possible there's a bad chip configuration which will result with
PCIe IOV capabilities, but with no available interrupts for VFs.

In such case, we want to gracefully prevent the PF from initializing its
IOV capabilities rather than encounter difficulties further along the way.

e261199872 bnx2x: Safe bnx2x_panic_dump()
The bnx2x panic dump spills a lot of information from the driver's
fastpath, but may be called while some of the fastpath is uninitialized.

This patch verifies that pointers are already allocated before dereferencing
them to prevent possible kernel panics.

eeed018cbf bnx2x: Add timestamping and PTP hardware clock support
This adds a PHC to the bnx2x driver. Driver supports timestamping send/receive
PTP packets, as well as adjusting the on-chip clock.

The driver has been tested with linuxptp project.
