From eaeadb50ea4d65e6fdbde7224b089dca6a41ff1e Mon Sep 17 00:00:00 2001 From: Andre Przywara <andre.przywara@arm.com> Date: Mon, 6 Jul 2020 01:40:39 +0100 Subject: [PATCH] net: sun8i_emac: Drop unneeded cache invalidation before sending There is no reason to invalidate a TX descriptor before we are setting it up, as we will only write to a field. Remove the not needed invalidate_dcache_range() call.
