[LEDE-DEV] Fwd: revisited: Nanostation m5 XW ethernet patch gone

Mon Mar 12 12:40:38 PDT 2018

The NS M5 XW has an internal switch.   Could you be running into the
issue where a given port can only do tagged or un-tagged, but not
both?  The NS M5 XW never had the issue related to this thread, which
is unique to UBNT's use of a separate AR803x with GPIO wiring to reset
it.

By the way, if anyone is interested I applied a stack of patches,
including Felix's AR803x fixes, to Chaos Calmer.  You can find these
here (and the 5 prior change sets):
