Subject: [net-next 08/15] net/mlx5: Lag, store number of ports inside lag object
Date: Mon,  9 May 2022 22:57:36 -0700	[thread overview]
Message-ID: <20220510055743.118828-9-saeedm@nvidia.com> (raw)
In-Reply-To: <20220510055743.118828-1-saeedm@nvidia.com>

From: Mark Bloch <mbloch@nvidia.com>

Store the number of lag ports inside the lag object. Lag object is a single
shared object managing the lag state of multiple mlx5 devices on the same
physical HCA.

Downstream patches will allow hardware lag to be created over devices with
more than 2 ports.
