While sending FW update cmds to the FW, the driver specifies the "type"
of each component that needs to be flashed. The FW then picks the offset
in the flash area at which the componnet is to be flashed. This doesn't work
when new components that the current FW doesn't recognize, need to be
flashed. Recent FWs (10.2 and above) support a scheme of FW-update wherein
the "offset" of the component in the flash area can be specified instead
of the "type". This patch uses the "offset" based FW-update mechanism and
only when it fails, it fallsback to the old "type" based update.

Intel Wired LAN Driver Updates 2015-02-05
This series contains updates to fm10k, ixgbe and ixgbevf.
Matthew fixes an issue where fm10k does not properly drop the upper-most four
bits on of the VLAN ID due to type promotion, so resolve the issue by not
masking off the bits, but by throwing an error if the VLAN ID is out-of-bounds.
Then cleans up two cases where variables were not being used, but were
being set, so just remove the unused variables.
Don cleans up sparse errors in the x550 family file for ixgbe. Fixed up
a redundant setting of the default value for set_rxpba, which was done
twice accidentally. Cleaned up the probe routine to remove a redundant
attempt to identify the PHY, which could lead to a panic on x550. Added
support for VXLAN receive checksum offload in x550 hardware. Added the
Ethertype Anti-spoofing feature for affected devices.
Emil enables ixgbe and ixgbevf to allow multiple queues in SRIOV mode.
Adds RSS support for x550 per VF. Fixed up a couple of issues introduced
in commit 2b509c0cd2 ("ixgbe: cleanup ixgbe_ndo_set_vf_vlan"), fixed
setting of the VLAN inside ixgbe_enable_port_vlan() and disable the
"hide VLAN" bit in PFQDE when port VLAN is disabled. Cleaned up the
setting of vlan_features by enabling all features at once. Fixed the
ordering of the shutdown patch so that we attempt to shutdown the rings
more gracefully. We shutdown the main Rx filter in the case of Rx and we
set the carrier_off state in the case of Tx so that packets stop being
delivered from outside the driver. Then we shutdown interrupts and NAPI,
then finally stop the rings from performing DMA and clean them. Added
code to allow for Tx hang checking to provide more robust debug info in
the event of a transmit unit hang in ixgbevf. Cleaned up ixgbevf logic
dealing with link up/down by breaking down the link detection and up/down
events into separate functions, similar to how these events are handled
in other drivers. Combined the ixgbevf reset and watchdog tasks into a
single task so that we can avoid multiple schedules of the reset task when
we have a reset event needed due to either the mailbox going down or
transmit packets being present on a link down.

OVS userspace already probes the openvswitch kernel module for
OVS_ACTION_ATTR_SET_MASKED support. This patch adds the kernel module
implementation of masked set actions.
The existing set action sets many fields at once. When only a subset
of the IP header fields, for example, should be modified, all the IP
fields need to be exact matched so that the other field values can be
copied to the set action. A masked set action allows modification of
an arbitrary subset of the supported header bits without requiring the
rest to be matched.
Masked set action is now supported for all writeable key types, except
for the tunnel key. The set tunnel action is an exception as any
input tunnel info is cleared before action processing starts, so there
is no tunnel info to mask.
The kernel module converts all (non-tunnel) set actions to masked set
actions. This makes action processing more uniform, and results in
less branching and duplicating the action processing code. When
returning actions to userspace, the fully masked set actions are
converted back to normal set actions. We use a kernel internal action
code to be able to tell the userspace provided and converted masked
set actions apart.

The remove logic properly searched the remaining chain for a matching
entry with an identical hash but it did this while searching from both
the old and new table. Instead in order to not leave stale references
behind we need to:
1. When growing and searching from the new table:
Search remaining chain for entry with same hash to avoid having
the new table directly point to a entry with a different hash.
2. When shrinking and searching from the old table:
Check if the element after the removed would create a cross
reference and avoid it if so.
These bugs were present from the beginning in nft_hash.
Also, both insert functions calculated the hash based on the mask of
the new table. This worked while growing. Wwhile shrinking, the mask
of the inew table is smaller than the mask of the old table. This lead
to a bit not being taken into account when selecting the bucket lock
and thus caused the wrong bucket to be locked eventually.

During a resize, when two buckets in the larger table map to
a single bucket in the smaller table and the new table has already
been (partially) linked to the old table. Removal of an element
may result the bucket in the larger table to point to entries
which all hash to a different value than the bucket index. Thus
causing two buckets to point to the same sub chain after unzipping.
This is not illegal *during* the resize phase but after it has
completed.
Keep the old table around until all of the unzipping is done to
allow the removal code to only search for matching hashed entries
during this special period.

rhashtable currently allows to use a bucket lock per bucket. This
requires multiple levels of complicated nested locking because when
resizing, a single bucket of the smaller table will map to two
buckets in the larger table. So far rhashtable has explicitly locked
both buckets in the larger table.
By excluding the highest bit of the hash from the bucket lock map and
thus only allowing locks to buckets in a ratio of 1:2, the locking
can be simplified a lot without losing the benefits of multiple locks.
Larger tables which benefit from multiple locks will not have a single
lock per bucket anyway.

The value computed by key_hashfn() is used by rhashtable_lookup_compare()
to traverse both tables during a resize. key_hashfn() must therefore
return the hash value without the buckets mask applied so it can be
