Using that register is AR93xx specific, and makes the mode incompatible with earlier chipsets. In some early versions, these flags were apparently applied at the wrong point in time and thus did not cause connectivity issues, however now they are causing problems, as pointed out in this OpenWrt ticket: https://dev.openwrt.org/ticket/14916 Signed-off-by: Felix Fietkau Signed-off-by: John W.
