Subject: [PATCH net-next v3 4/7] devlink: Add new "event_eq_size" generic device param
Date: Wed, 8 Dec 2021 16:17:19 +0200 [thread overview]
Message-ID: <20211208141722.13646-5-shayd@nvidia.com> (raw)
In-Reply-To: <20211208141722.13646-1-shayd@nvidia.com>
Add new device generic parameter to determine the size of the
asynchronous control events EQ.
For example, to reduce event EQ size to 64, execute:
$ devlink dev param set pci/0000:06:00.0 \
name event_eq_size value 64 cmode driverinit
$ devlink dev reload pci/0000:06:00.0
