be2net: patch set
Hi Dave, pls consider applying the following patch-set to the
net-next tree. It has 5 code/style cleanup patches and 4 patches that
add functionality to the driver.
Patch 1 moves routines that were not needed to be in be.h to the respective
src files, to avoid unnecessary compilation.
Patch 2 replaces (1 << x) with BIT(x) macro
Patch 3 refactors code that checks if a FW flash file is compatible
with the adapter. The code is now refactored into 2 routines, the first one
gets the file type from the image file and the 2nd routine checks if the
file type is compatible with the adapter.
Patch 4 adds compatibility checks for flashing a FW image on the new
Skyhawk P2 HW revision.
Patch 5 adds support for a new "offset based" flashing scheme, wherein
the driver informs the FW of the offset at which each component in the flash
file is to be flashed at. This helps flashing components that were
previously not recognized by the running FW.
Patch 6 simplifies the be_cmd_rx_filter() routine, by passing to it the
filter flags already used in the FW cmd, instead of the netdev flags that
were converted to the FW-cmd flags.
Patch 7 introduces helper routines in be_set_rx_mode() and be_vid_config()
to improve code readability.
Patch 8 adds processing of port-misconfig async event sent by the FW.
Patch 9 removes unnecessary swapping of a field in the TX desc.
====================

The 32-bit fields of a tx-wrb are little endian. The driver is currently
using be_dws_le_to_cpu() routine to swap (cpu to le) all the fields of
a tx-wrb. So, the rsvd field is also unnecessarily swapped.
This patch fixes this by individually swapping the required fields.
Also, the type of the fields in eth_tx_wrb{} is now changed to __le32
from u32 to avoid sparse warnings.

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.

When using per channel DMA interrupts the transmit interrupt (TI) and the
receive interrupt (RI) are masked off so as to not generate an interrupt
to the main ISR. However, should another interrupt fire for the DMA channel
that is handled by the main ISR the TI/RI bits can still be set. This
will cause the wrong and uninitialized napi structure to be used causing a
panic. Add a check to be sure per channel DMA interrupts are not enabled
before acting on those bit flags.

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.

ifla_vf_policy[] is wrong in advertising its individual member types as
NLA_BINARY since .type = NLA_BINARY in combination with .len declares the
len member as *max* attribute length [0, len].
The issue is that when do_setvfinfo() is being called to set up a VF
through ndo handler, we could set corrupted data if the attribute length
is less than the size of the related structure itself.
The intent is exactly the opposite, namely to make sure to pass at least
data of minimum size of len.
