Specific MAC address impact performance

[Yu-Chieh]

Hi Ben,
I also geuss that mignt be BSSID mask issue, however i have no idea
about the patten
I can find bssid_mask function in ath5k and ath9k but not in ath10k.
Do your suggest me to use XX:XX:XX:YY:YY:XX, XX should be same and YY
could be different?

Thanks.

Jay
