Subject: [dpdk-stable] [PATCH] net/nfp: fix MTU settings
Date: Fri, 24 Nov 2017 14:23:48 +0000 [thread overview]
Message-ID: <1511533428-34831-1-git-send-email-alejandro.lucero@netronome.com> (raw)
The wrong mtu length was used for configuring the hardware. The
max_rx_pktlen reported was also wrong.
Fixes: defb9a5dd156 ("nfp: introduce driver initialization")
