Subject: [PATCH 2/2] net/mlx5: apply default tuning to future speeds
Date: Tue,  5 Mar 2024 14:12:41 +0100	[thread overview]
Message-ID: <20240305131241.3132128-2-thomas@monjalon.net> (raw)
In-Reply-To: <20240305131241.3132128-1-thomas@monjalon.net>

Some default parameters for number of queues and ring size
are different starting with 100G speed capability.

Instead of checking all speed above 100G, make sure it is applied
for any speed capability newer than 100G (including 400G for instance).
