From 361913ad6f8c05fc541fe4bfdae3b0dc095ae3af Mon Sep 17 00:00:00 2001 From: Daria Kolistratova Date: Tue, 26 Jun 2018 18:38:56 +0100 Subject: [PATCH] net/ena: fix SIGFPE with 0 Rx queue When the number of rx queues is 0 (what can be when application does not receive) failed with SIGFPE. It happens when the application is also requesting ETH_MQ_RX_RSS_FLAG in the rte_dev->data->dev_conf.rxmode.mq_mode. Fixed adding zero rx queues check.
