From c2b559ed8683ffb5a7bdd9e71b3803b231623c86 Mon Sep 17 00:00:00 2001 From: Yevgeny Petrilin Date: Mon, 29 Dec 2008 18:38:21 -0800 Subject: mlx4_en: Verify number of RX rings doesn't exceed MAX_RX_RINGS Required in cases were dev->caps.num_comp_vectors > MAX_RX_RINGS. For current values this would happen on machines that have more then 16 cores. Signed-off-by: Yevgeny Petrilin Signed-off-by: David S.
