====================
mlx4: Add CHECKSUM_COMPLETE support

These patches from Shani, Matan and myself add support for
CHECKSUM_COMPLETE reporting on non TCP/UDP packets such as
GRE and ICMP. I'd like to deeply thank Jerry Chu for his
innovation and support in that effort.

Based on the feedback from Eric and Ido Shamay, in V2 we dropped
the patch which removed the calls to napi_gro_frags() and added
a patch which makes the RX code to go through that path
regardless of the checksum status.
