Subject: [PATCH net-next 0/2] cxgb4: speed up reading on-chip memory

This series of patches speed up reading on-chip memory (EDC and MC)
by using AVX intrinsic instructions when available.

Patch 1 exports callback to register supported intrinsic instructions
when available.  Also rework logic to read EDC and MC.

Patch 2 adds AVX CPU intrinsic instructions to read EDC and MC
256-bits at a time.  Also fallback to regular 32-bit reads, if AVX is
not available.

Thanks,
Rahul
