Subject: [PATCH v1 3/6] staging: qlge: support force_coredump option for devlink health dump
Date: Thu, 8 Oct 2020 19:58:05 +0800 [thread overview]
Message-ID: <20201008115808.91850-4-coiby.xu@gmail.com> (raw)
In-Reply-To: <20201008115808.91850-1-coiby.xu@gmail.com>
With force_coredump module paramter set, devlink health dump will reset
the MPI RISC first which takes 5 secs to be finished.
