Subject: [PATCH 2/2] Do not set shared_ports when nreq > MAX_MSIX
Date: Tue,  6 Oct 2015 17:27:09 -0400	[thread overview]
Message-ID: <1444166829-17638-2-git-send-email-clsoto@linux.vnet.ibm.com> (raw)
In-Reply-To: <1444166829-17638-1-git-send-email-clsoto@linux.vnet.ibm.com>

From: Carol L Soto <clsoto@linux.vnet.ibm.com>

If we get MAX_MSIX interrupts would like to have each receive ring
with his own msix interrupt line.

Fixes: 9293267a3e2a ('net/mlx4_core: Capping number of requested MSIXs to MAX_MSIX')
