Thanks; I have that working now. We weren't setting the MAC address on<br>
the rtap interface, so the kernel was refusing to bring the interface up<br>
because its address was invalid. That check for a valid MAC address<br>
doesn't happen in the older kernel that we're using on the XOs.<br>
<br>
Still, it doesn't do anything _but_ sniff, afaict. I've actually removed<br>
the bit of code I quoted, which prevents any TX on the eth%d and msh%d<br>
interfaces when we're in monitor mode (as well as cleaning up the set of<br>
4 or 5 nested functions in the TX path) -- but still it doesn't actually<br>
work, and even association fails. Although association is failing a lot<br>
of the time here in 1cc anyway; maybe that's not related to rtap.<br>
Investigating now...<br>
