Merge branch 'bnx2x'
Yuval Mintz says:
====================
bnx2x: new features patch series
This patch series adds/fixes several new features in the bnx2x driver -
it adds support for loading the bnx2x over an UNDI running on a Multi-function
device, adds missing bits for PCIe AER support and enables VFs to properly
configure multicast filters
(In addition, it also contains some small improvements in driver behaviour).
Please consider applying these patches to `net-next'.
Changes from previous versions
------------------------------
v2:
- Fixed comment typo in patch 4 (propogate --> propagate)
