From: Felix Fietkau Date: Sun, 20 Dec 2015 14:25:45 +0000 (+0000) Subject: ar8216: rework/fix AR8337 MAC swap handling X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=814d70b2fdabec79c75b41460c10b5a63cc20b59;p=librecmc%2Flibrecmc.git ar8216: rework/fix AR8337 MAC swap handling In r45970 the MAC swap handling was made opt-in, however some boards have been forgotten during the conversion. Since the reference design uses this MAC swapping, and pretty much all known boards using this chip seem to do so too, enabling the swapping is a more reasonable default than leaving it disabled. Change the code to still allow boards to opt-out of this.
