From 905726c1c5a3ca620ba7d73c78eddfb91de5ce28 Mon Sep 17 00:00:00 2001 From: "Li, Liang Z" Date: Sat, 27 Jun 2015 07:17:26 +0800 Subject: xen-netfront: Remove the meaningless code The function netif_set_real_num_tx_queues() will return -EINVAL if the second parameter < 1, so call this function with the second parameter set to 0 is meaningless.
