From 3783d43752eab247ed296ac8d5022484ed969151 Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Thu, 8 Aug 2019 18:17:37 +0200 Subject: [PATCH] samples/bpf: xdp_fwd rename devmap name to be xdp_tx_ports MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The devmap name 'tx_port' came from a copy-paste from xdp_redirect_map which only have a single TX port. Change name to xdp_tx_ports to make it more descriptive.
