Merge branch 'be2net-next'

Sathya Perla says:

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

Patch 1 fixes a regression caused by a previous commit on net-next.
Old versions of BE3 FW may not support cmds to re-provision (and hence
optimize) resources/queues in SR-IOV config. Do not treat this FW cmd
failure as fatal and fail the function initialization. Instead, just
enable SR-IOV with the resources provided by the FW.

Patch 2 ignores a VF mac address setting if the new mac is already active
on the VF.

Patch 3 adds support to delete a FW-dump via ethtool on Lancer adapters.
