From: Adrian Chadd To: Ben Greear Cc: Sujith Manoharan , "linux-wireless@vger.kernel.org" , "ath9k-devel@lists.ath9k.org" Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-wireless-owner@vger.kernel.org List-ID: Ah, Osprey is AR93xx series stuff. Well, not strictly speaking, but that "family." I'd have to go and check what the current state of all the latest 11n chips are. Luis, Sujith and Felix would know better than I; I'm still stuck in the land of AR92xx in FreeBSD (at least for the next few weeks.) Also, FreeBSD on 2x2 (AR9160) hostap: TCP sta -> hostap: [SUM] 0.0-10.0 sec 178 MBytes 149 Mbits/sec UDP sta -> hostap: [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 3] 0.0-10.1 sec 274 MBytes 228 Mbits/sec 0.135 ms 17045/212291 (8%) TCP is around the expected spot, but I've seen it around 160MBit in the past. I think I messed up something with BAR/TX scheduling. The UDP RX is likely another scheduling issue; I seem to be occasionally overflowing the RX descriptor list. In any case, I'll fix it up and report back, just as a comparison point. Adrian
