Subject: [dpdk-dev] [PATCH 2/2] net/ixgbe: fix l3fwd start failed on PF
Date: Fri, 3 Nov 2017 01:04:32 +0800 [thread overview]
Message-ID: <20171102170432.168194-2-yanglong.wu@intel.com> (raw)
In-Reply-To: <20171102170432.168194-1-yanglong.wu@intel.com>
which occurred when the SRIOV is active and tx_q > rx_q.
The number of nb_q_per_pool should equeal to max number
of queues supported by HW not nb_rx_q.
Fixes: 27b609cbd1c6 (ethdev: move the multi-queue mode
check to specific drivers)
