Merge branch 'cxgb4-collect-hardware-logs-via-ethtool'

Rahul Lakkireddy says:

====================
cxgb4: collect hardware logs via ethtool

Collect more hardware logs via ethtool --get-dump facility.

Patch 1 collects on-chip memory layout information.

Patch 2 collects on-chip MC memory dumps.

Patch 3 collects HMA memory dump.

Patch 4 evaluates and skips TX and RX payload regions in memory dumps.

Patch 5 collects egress and ingress SGE queue contexts.

Patch 6 collects PCIe configuration logs
====================
