Subject: [PATCH net-next 1/3] ionic: make the command timeout per device
Date: Mon, 2 Nov 2026 22:27:39 +0000 [thread overview]
Message-ID: <20261102-b4-ionic-cmd-timeout-v1-1-2f75c2d0a0c7@amd.com> (raw)
In-Reply-To: <20261102-b4-ionic-cmd-timeout-v1-0-2f75c2d0a0c7@amd.com>
From: Arun Kumar Prakash <ArunKumar.Prakash@amd.com>
Device and admin queue command waits, and the firmware heartbeat check
interval, use the compile-time DEVCMD_TIMEOUT. Make the timeout a
per-device value, so that it can be made configurable through a devlink
parameter, and export it to the RDMA driver through
ionic_cmd_timeout().
No functional change.
