====================
be2net: patch-set

The following patch-set has two new feature additions, and a few
minor fixes and cleanups.
Pls consider applying to the net-next tree. Thanks.

v2 changes:
        a) dropped the "don't enable pause by default" patch
        b) described how the "spoof check" works in patch 1's commit log
	c) I had to update our email addresses from "@emulex" to
	   "@avagotech". I'll send a separate patch updating the
	   maintainers

Patch 1 adds support for the "spoofchk" knob for VFs.
When it is enabled, "spoof checking" is done for both MAC-address
and VLAN. For each VF, the HW ensures that the source MAC address
(or vlan) of every outgoing packet of the VF exists in the MAC-list
(or vlan-list) configured for RX filtering for that VF.
If not, the packet is dropped and an error is reported to the driver
in the TX completion.

Patch 2 improves interrupt moderation on Skyhawk-R chip by using
the EQ-DB mechanism to set a "re-arm to interrupt" delay. Currently
interrupt moderation is adjusted by calculating and configuring an
EQ-delay every second. This is done via a FW-cmd. This patch uses
the EQ_DB facility to calculate and set the interrupt delay every 1ms.
This helps moderating interrupts better when the traffic is bursty.

Patch 3 adds L3/L4 error accounting to BE3 VFs, by passing L3/4 error
packets to the network stack.

Patch 4 adds an extra FW-cmd error value check in the driver to identify
an "out of vlan filters" scenario.

Patch 5 stops enabling pause by default as this setting fails in
some HW-configs where priority pause is enabled in FW. If the user
tries to do the same, an appropriate error is returned via ethtool.

Patch 5 posts the full RXQ in be_open() to prevent packet drops due to
bursty traffic when the interface is enabled.

Patch 6 refactors the be_check_ufi_compatibility() routine, that checks
to see if a UFI file meant for a lower rev of a chip is being flashed
on a higher rev, to make it simpler.

Patch 7 replaces the usage of !be_physfn() macro with be_virtfn()
that is already avialble in the driver.

Patch 8 updates the year in the copyright text to 2015.

Path 9 bumps up the driver version to 10.6.02.
