Subject: [PATCH net-next v2 0/8] cxgb4: add support to get hardware debug logs via ethtool

This series of patches add support to collect hardware debug logs
via ethtool --get-dump facility.

Currently supports:

Memory dumps - Collects on-chip EDC0 and EDC1 dumps.
Hardware dumps - Collects firmware and hardware dumps.

Patch 1 adds ethtool set/get dump data.  It also adds template header
that precedes dump data.  This template header gives additional
information needed for extracting and decoding the collected dump
data.

Patch 2 adds base to collect dumps.  Also collects regdump.

Patch 3 collects on-chip EDC0 and EDC1 memory dumps.

Patch 4 collects firmware mbox log and device log.

Patch 5 updates base API for accessing TP indirect registers.

Patch 6 collects hardware TP module dump.

Patch 7 collects hardware SGE, PCIE, PM, UP CIM, MA, and HMA
module dumps.

Patch 8 collects hardware IBQ and OBQ dump.

Thanks,
Rahul

v2:
- Prefix symbols that pollute global namespace in files starting
  with cxgb4_* with "cxgb4_"
- Prefix symbols that pollute global namespace in files starting
  with cudbg_* with "cudbg_"
- Make cudbg_collect_mem_info() static.
