From 9919d5bd01b9eaf4928439e804dd70de24ea9637 Mon Sep 17 00:00:00 2001 From: Vipul Pandya Date: Thu, 14 Mar 2013 05:09:04 +0000 Subject: [PATCH] RDMA/cxgb4: Fix onchip queue support for T5 T5 adapter does not support onchip queue memory. Present logic fails to allocate QP for T5 and returns an error. Also, if module parameter ocqp_support is zero then we are unable to allocate QP which should not be the case. Ideally if ocqp_support parameter is 0 or onchip queue support is disable then host QP should be allocated before returning an error. Signed-off-by: Vipul Pandya Signed-off-by: David S.
