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.
