Subject: RFC: Add precise timing to wifi association messages?
Date: Wed, 13 Nov 2013 09:58:14 -0800 [thread overview]
Message-ID: <5283BDB6.5020700@candelatech.com> (raw)
Any interest in a patch looking similar to that below for the
5 or so messages related to association? I found it useful for
tracking down why it was taking longer than expected to roam
to a new AP...
diff --git a/net/mac80211/mlme.c b/net/mac80211/mlme.c
index d2510c0..2e96813 100644
--- a/net/mac80211/mlme.c
+++ b/net/mac80211/mlme.c
@@ -908,6 +908,12 @@ static void ieee80211_send_assoc(struct ieee80211_sub_if_data *sdata)
memcpy(pos, assoc_data->ie + offset, noffset - offset);
}
+ {
+ struct timeval tv;
+ do_gettimeofday(&tv);
+ sdata_info(sdata, "send_assoc, calling prepare_tx at: %lu.%lu\n",
+ tv.tv_sec, tv.tv_usec);
+ }
drv_mgd_prepare_tx(local, sdata);
IEEE80211_SKB_CB(skb)->flags |= IEEE80211_TX_INTFL_DONT_ENCRYPT;
Thanks,
Ben
