Subject: [PATCH net 2/2] qed: Correct rdma params configuration
Date: Wed, 9 Nov 2016 22:48:44 +0200	[thread overview]
Message-ID: <1478724524-16940-3-git-send-email-Yuval.Mintz@cavium.com> (raw)
In-Reply-To: <1478724524-16940-1-git-send-email-Yuval.Mintz-YGCgFSpz5w/QT0dZR+AlfA@public.gmane.org>

From: Ram Amrani <Ram.Amrani-YGCgFSpz5w/QT0dZR+AlfA@public.gmane.org>

Previous fix has broken RoCE support as the rdma_pf_params are now
being set into the parameters only after the params are alrady assigned
into the hw-function.

Fixes: 0189efb8f4f8 ("qed*: Fix Kconfig dependencies with INFINIBAND_QEDR")
