Subject: iwlwifi: fix PAN parameters while scanning
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=27eafdda7714d5b189c175e71ab22c72c90ba93e;p=openwrt%2Fstaging%2Fblogic.git

iwlwifi: fix PAN parameters while scanning

When only the PAN side was active, we gave no
time to the WLAN context, which is OK unless
we are scanning, which always happens on the
WLAN context. Fix this.
