:-) You mean my code currently has bugs? Never! :) It's still definitely a work in progress. Just note - the AR5416 support is definitely not being tested during this pass; there are limitations which I've not yet worked around. :) In this instance - I know there are issues with the BAW (Block-ack window) tracking. Specifically, when the interface is scanning, the software TX queue is purged and the BAW isn't adjusted correctly. I'm working on adapting ath_rate_sample to "mostly work" with 802.11n (specifically, just enough to pick a low-error rate for 11n TX) and when that's done, I'll continue working on fixing up the BAW tracking. There's a bunch of rather invasive changes I think I'll have to do to net80211 and ath in order to get it working properly. That said, I'm glad it's working for you. :) I'm getting about 130mbit/sec via TCP at the moment as well. I just need to fix up the rate control stuff a little more.. :) Adrian On 5 September 2011 21:11, Berislav Purgar <bpurgar@gmail.com> wrote: > On Sun, Sep 4, 2011 at 11:06 PM, Adrian Chadd <adrian@freebsd.org> wrote: > >> On 5 September 2011 02:27, Berislav Purgar <bpurgar@gmail.com> wrote: >> > I am interested in the progress of the implementation code for the >> AMPD-TX ? >> >> Hi! >> >> My atheros work is in SVN - svn:// >> svn.freebsd.org/base/user/adrian/if_ath_tx . >> iwn, mwl and ral already support AMPDU-TX. >> >> >> adrian >> > > ok tnx. i tried and it works but i have bunch of error in log : > > <snip>ath0: ath_tx_default_comp: dobaw should've been cleared! > ath0: ath_tx_tid_drain: wasn't added: seqno 3328 > ath0: ath_tx_default_comp: dobaw should've been cleared! > ath0: ath_tx_tid_drain: wasn't added: seqno 3329 > ath0: ath_tx_default_comp: dobaw should've been cleared! > ath0: ath_tx_tid_drain: wasn't added: seqno 3330 > ath0: ath_tx_default_comp: dobaw should've been cleared! > ath0: ath_tx_tid_drain: wasn't added: seqno 3341 > ath0: ath_tx_default_comp: dobaw should've been cleared! > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=120, head=120, > tail=8) > ath0: ath_tx_tid_drain: wasn't added: seqno 3359 > ath0: ath_tx_default_comp: dobaw should've been cleared! > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=125, head=125, > tail=26) > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=126, head=126, > tail=30) > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=3, head=3, tail=30) > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=4, head=4, tail=30) > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=7, head=7, tail=30) > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=8, head=8, tail=30) > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=17, head=17, tail=30) > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=18, head=18, tail=30) > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=25, head=25, tail=30) > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=26, head=26, tail=30) > ath0: ath_tx_addto_baw: ba packet dup (index=0, cindex=29, head=29, tail=30) > ath0: device timeout > ath0: ath_tx_tid_drain: wasn't added: seqno 3302 > ath0: ath_tx_default_comp: dobaw should've been cleared! > ath0: ath_tx_tid_drain: wasn't added: seqno 3303 > ath0: ath_tx_default_comp: dobaw should've been cleared! > ath0: ath_tx_tid_drain: wasn't added: seqno 3304 > ath0: ath_tx_default_comp: dobaw should've been cleared! > <snip> > > card is linksys WPC-300N ver2 - AR5008/5416 .. freebsd-9-beta2 > i managed to get speed on TCP 120Mbits/s - UDP 170Mbits/s (tested with > iperf) .. > > Beri > _______________________________________________ > freebsd-wireless@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-wireless > To unsubscribe, send any mail to "freebsd-wireless-unsubscribe@freebsd.org" >
