From 119b8ab2c2eac237ec4e9c4d0ed53df22b5c6978 Mon Sep 17 00:00:00 2001 From: blogic Date: Wed, 16 Mar 2016 09:27:04 +0000 Subject: [PATCH 1/1] ar71xx: Clear bits in ath79_setup_qca955x_eth_cfg Some u-boot versions for QCA955x set currently not cleared bits depending on the used link speed. This breaks the rx/tx under OpenWrt. The mach-*.c file is responsible to select the correct configuration bits and thus the ath79_setup_qca955x_eth_cfg has to clear the unset.
