Subject: [PATCH v4 6/8] staging: qlge: remove mpi_core_to_log which sends coredump to the kernel ring buffer
Date: Sat, 23 Jan 2021 18:46:11 +0800 [thread overview]
Message-ID: <20210123104613.38359-7-coiby.xu@gmail.com> (raw)
In-Reply-To: <20210123104613.38359-1-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
