I used pkt size 31-1200 bytes

not with the current code. In my function i disable intr, disable rx, and than
call ath5k_hw_channel(btw it sets rxbuf, i didnt see it before). I observed wen
i only call ath5k_hw_channel to switch i am able to receive pkts bt with heavy
pkt loss. But wen i set txpower tables and switch channel pkt loss is minimal.
Sams & legacy HAL both set txpower tables wen switching channels.
