The BSS channel isn't updated after a CSA has completed.
The BSS channel (iv_bss->ni_chan) is only set during an explicit
channel change (via an ioctl); it isn't at all updated through the CSA
code path.
This patch kicks the channel update after the CSA is complete,
changing the channel of all VAPs in the CSA state.
It does resolve the issue (ie, ifconfig wlanX in STA mode shows the
wrong BSS channel.)
Thanks,
adrian
