Subject: [PATCH 3/3] mlx4_en: use MLX4_LEAST_ATTACHED_VECTOR for TX cqs
Date: Thu, 13 May 2010 12:25:23 +0300 [thread overview]
Message-ID: <4BEBC583.4050308@mellanox.co.il> (raw)
Instead always setting all the TX cqs to use comletion vector 0,
let the mlx4_core to distribute them to avoid situation where some eqs
are very loaded while other do nothing.
