kern/181100: [bwi] Turning up bwi0 crashes / deadlocks the kernel

[Adrian Chadd]

Hi!

THanks for the report!

This is my fault. But, is bwi actually doing 11n rates?

See, that's just odd. If it's a non-11n (MCS) rate, then it should be
2x the speed, which is 65MBit - which is odd, as that looks more like
an MCS rate speed than what the NIC should do.

Can you get a crashdump?

(Can someone send me a bwi NIC for a PC?)
