From 12da1deb89806c0a0d974948d11712e4f06c6b93 Mon Sep 17 00:00:00 2001 From: Yanglong Wu Date: Wed, 10 Jan 2018 09:51:36 +0800 Subject: [PATCH] net/ixgbe: fix the failure of number of Tx queue check Tx_q check fails when the SRIOV is active and tx_q > rx_q. It has to use the maximum HW queue number for calculation, to get the right number of queue can be used.
