Subject: [PATCH net-next] mlx4: Bump up MAX_MSIX from 64 to 128
Date: Thu, 9 Jan 2020 11:23:17 -0800 [thread overview]
Message-ID: <20200109192317.4045173-1-jonathan.lemon@gmail.com> (raw)
On modern hardware with a large number of cpus and using XDP,
the current MSIX limit is insufficient. Bump the limit in
order to allow more queues.
