From 62fcc0ac6151b57b1177ac8b346341fc4dac3bb3 Mon Sep 17 00:00:00 2001 From: John Lo Date: Tue, 31 Oct 2017 14:31:10 -0400 Subject: Fix set interface mac address API to be endian neutral Store and pass MAC address as 6 byte u8 array instead of u64 to make MAC address handling in set interface MAC endian neutral. The previous API handler only works for little endian.
