Merge branch 'bnx2x' 

Yuval Mintz says:

====================
bnx2x: Bug fixes patch series

This patch series contains fixes for various flows - several SR-IOV issues
are fixed, ethtool callbacks (coalescing and register dump) are corrected,
null pointer dereference on error flows is prevented, etc.

Changes from V1
---------------
 - Patch 2  "bnx2x: Prevent an illegal pointer dereference during panic"
   is revised, with improved handling of edge cases.
====================
