From b044cc1dee8f8af4dcad6ca2ef3ff4f577b79229 Mon Sep 17 00:00:00 2001 From: Jimmy Du Date: Tue, 6 Jun 2017 11:58:54 -0500 Subject: [PATCH] net: Get mac address from driver as seed Previously seeded by obtaining mac addr from env. If mac addr was never set, rand would output 0. This fix obtains the mac addr from driver instead.
