Subject: [PATCH net-next 00/11] bnxt_en: Add context memory dump to coredump

The driver currently supports Live FW dump and crashed FW dump.  On
the newer chips, the driver allocates host backing store context
memory for the chip and FW to store various states.  The content of
this context memory will be useful for debugging.  This patchset
adds the context memory contents to the ethtool -w coredump using
a new dump flag.

The first patch is the FW interface update, followed by some
refactoring of the context memory logic.  Next, we add support for
some new context memory types that contain various FW debug logs.
After that, we add a new dump flag and the code to dump all the
available context memory during ethtool -w coredump.

Hongguang Gao (3):
  bnxt_en: Refactor bnxt_free_ctx_mem()
  bnxt_en: Add a 'force' parameter to bnxt_free_ctx_mem()
  bnxt_en: Do not free FW log context memory

Michael Chan (2):
  bnxt_en: Update firmware interface spec to 1.10.3.85
  bnxt_en: Add a new ethtool -W dump flag

Shruti Parab (5):
  bnxt_en: Add mem_valid bit to struct bnxt_ctx_mem_type
  bnxt_en: Allocate backing store memory for FW trace logs
  bnxt_en: Manage the FW trace context memory
  bnxt_en: Add 2 parameters to bnxt_fill_coredump_seg_hdr()
  bnxt_en: Add FW trace coredump segments to the coredump

Sreekanth Reddy (1):
  bnxt_en: Add functions to copy host context memory
