This mail thread seem to have gone dark since december with seemingly
no conclusion.

I have tried to collect the experiences reported on the wiki page:


As you can see from the table, for me it only works with 0x6f.
Chris, for whom both 0x3e and 0x6f work has a rev 2 AR9344. I have
a rev 3. AR8327 is rev. 4 on both our routerboards. No info what
rev Matt has, he is the other one reporting that only 0x6f works. 

I am also observing some amount of increases in switch 0 port 0
RxBadByte (aka: from CPU to AR8327). It seems to happen for
all type of traffic sent from CPU to switch, eg: whether i inject
it from WiFi or from a 100 Mbps port, and whether i send it out
on an untagged port (lan) or tagged one (from CPU, Wan).

I have not really identified any noticeable performance impact from
this effect through.

Would be nice to hear some logic why 0x6f is the right value.
