That is interesting, but there is no reason to reject my diff, I think. > athn0: AR9380 rev 3 (2T2R), ROM rev 0, address 00:0e:8e:75:16:9a My device is 3T3R, and yours is 2T2R. It is unclear which rxchains are disabled on your device. The rxchain mask could 0x5 or 0x03. The driver has a few special cases for devices with less than 3 chains. I think it we would be better try to fix this in-tree, after my diff gets committed. Note that it looks like Damien did not have hardware when he wrote this driver. The log message of ar9003.c r1.1 says "AR9380 part is not tested (hardware is not available to the general public yet)." and when the first devices showed up in people's machines the kernel attached and then crashed immediately (see r1.72 of athn.c) which is why this part of the driver was eventually disabled (if_athn_pci.c r1.17). So there remain quite a few bugs which need to be fixed. It would be interesting to know how the FreeBSD driver handles your card.
