Bug description:
It was brought to my attention that BNX2X FIRMWARE is causing HW hangs
on kernels 3.13 and 3.16 (until next power-cycle):

Are likely to be given in syslog whenever this happens.
WORKAROUND: After providing the user a "linux-lts-vivid" and an
updated linux-firmware package
(https://launchpad.net/~inaddy/+archive/ubuntu/sf00080928/) the issue
was fixed after package installation and power-cycle -> Power cycle is
needed since previous firmware hangs HW until it is shutdown.
My comments:
"""
Actually after reading the Changelog for FW 7.10.51 (specifically the part
"Chip may stall in very rare cases under heavy traffic with FW GRO enabled.") I
think we might need to upgrade not only the FIRMWARE but also the DRIVER.

Firmware 7.10.51 is already present in Utopic but the commit to support it is
only in 3.18. It might be feasible to backport it to 3.16 (and use HWE) but
not sure about 3.13 (to be resolved if this new firmware/driver fixes the
issue).
"""
I'll provide more comments right after my backport attempt (of this
new version) is made.
