From a134321ef676723768973537bb9b49365ae2062e Mon Sep 17 00:00:00 2001 From: erik-smit Date: Sun, 28 Jun 2020 16:26:59 +0200 Subject: ftgmac100: fix dblac write test The test of the write of the dblac register was testing the old value instead of the new value. This would accept the write of an invalid value but subsequently refuse any following valid writes.
