[PATCH v2 5/7] staging: qlge: remove mpi_core_to_log which sends coredump to the kernel ring buffer

[Coiby Xu <coiby.xu@gmail.com>]

devlink health could be used to get coredump. No need to send so much
data to the kernel ring buffer.

   of questionable value. In particular, qlge_dbg.c has hundreds of lines of
   code bitrotting away in ifdef land (doesn't compile since commit
   18c49b91777c ("qlge: do vlan cleanup", v3.1-rc1), 8 years ago).
-* triggering an ethtool regdump will hexdump a 176k struct to dmesg depending
-  on some module parameters.
 * the flow control implementation in firmware is buggy (sends a flood of pause
   frames, resets the link, device and driver buffer queues become
   desynchronized), disable it by default
