Subject: [dpdk-dev] [PATCH] net/af_xdp: fix xdp_get_channels_info return value
Date: Fri, 12 Jul 2019 09:55:46 +0200 [thread overview]
Message-ID: <20190712075546.GA20880@localhost.localdomain> (raw)
Procedure xdp_get_channels_info was returning error code -1 in case of
ioctl command SIOCETHTOOL was not supported. This patch sets return
value back to 0 as it is valid case.
Fixes: 339b88c6a9 ("net/af_xdp: support multi-queue")
