From 6efc06725fade989675b5051b6e5a623473d0894 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Fri, 5 Jul 2019 10:16:20 -0700 Subject: [PATCH] cmdline: use new ethernet address parser Now that there is a version of ether_aton in rte_ether, it can be used by the cmdline ethernet address parser. Note: ether_aton_r can not be used in cmdline because the old code would accept either bytes XX:XX:XX:XX:XX:XX or words XXXX:XXXX:XXXX and we need to keep compatibility.
