From eafdcda4a854932c0319656de7bf3f017f17ae67 Mon Sep 17 00:00:00 2001 From: Michal Simek <michal.simek@xilinx.com> Date: Fri, 15 Oct 2021 15:03:29 +0200 Subject: [PATCH] net: gem: Disable broadcast setting There is no need for GEM to accepts broadcast packets because they are not handled by u-boot anyway. That's why use HW IP feature and don't waste time on these packats which will be dropped anyway.
