Subject: [PATCH] ath10k: implement drv_get_tsf for ibss merging
Date: Wed, 12 Feb 2014 17:37:24 +0800 [thread overview]
Message-ID: <1392197844-1223-1-git-send-email-yeohchunyeow@gmail.com> (raw)
Implement the get TSF by simply returning 0 so that IBSS
merging is happening. Otherwise, IBSS nodes that have similar
SSID naming won't merge. This is simply fooling the mac80211
that the TSF in the received beacon is higher than the local TSF.
