Subject: ath6kl: Indicate the roaming capability of the firmware
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=011a36e1193c02abcdc4853be09275a0fe9d1a32;p=openwrt%2Fstaging%2Fblogic.git

ath6kl: Indicate the roaming capability of the firmware

When the rssi of the current AP drops, both wpa_supplicant and the
firmware may do a background scan to find a better AP and try to
associate. This might lead to a race condition where both may try
to connect to some AP based on their scan results.

Since the firmware is capable of handling roaming, let
wpa_supplicant know about this capability so that it will back off
from bgscan based roaming.
