Merge branch 'cxgb4-collect-more-hardware-dumps-via-ethtool'

Rahul Lakkireddy says:

====================
cxgb4: collect more hardware dumps via ethtool

This series of patches collect more firmware and hardware dumps
via ethool --get-dump facility.

Patch 1 collects hardware logic analyzer dumps.

Patch 2 collects CIM queue configuration dump.

Patch 3 collects RSS dumps.

Patch 4 collects TID info dump.

Patch 5 collects MPS-TCAM dump.

Patch 6 collects PBT tables dump.

Patch 7 collects hardware scheduler and pace table dumps.

Patch 8 collects miscellaneous hardware information, including
path mtu, PM stats, TP clock info, congestion control, and VPD
data dumps.
====================
