[ath9k-devel] rx status registers for ar9280/ar9825/ar9287
Hallo all, i was playing with STBC functionality and wont to see more statistic about it. If i'm correct Some MACs can report if it got STBC frame or at least report duplicat frames. After greping the source, i'm confused about location of this registers. If i'm correct, STBC and Duplicate status bits loctaed together with GI and 2040. According to the source: ar9003_mac.c: rxs-rs_flags = (rxsp-status4 AR_GI) ? ATH9K_RX_GI : 0; mac.c: (ads.ds_rxstatus3 AR_GI) ? ATH9K_RX_GI : 0; So i it true for ar9280/ar9285/ar9287 and too? Shouldn't that be ds_rxstatus7 or some thing like this? And if it is different where should i add statistic for this chips? -- Regards, Oleksij ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel

Hi, There's no way to know that you received an STBC encoded frame. :( GI is short/long guard interval, not STBC.

I do not mean encoded frame, i mean only status flag. Looks like ar9271 provide it.

There's an STBC received status flag in the RX decriptor? Where? adrian ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel

I went digging through some internal stuff and I found that you're actually right, and right for the AR9280 and later chips. For the AR9280 and later: 3 3 stbcReceive packet STBC indicator. If this value is set then the baseband has received an STBC frames as indicated in the HT_PLCP. So, if you want to patch the pre-AR9380 path in mac80211, you should check that the chip is at least an AR9280. AR9285 and AR9287 is fine. AR5416/AR9130/AR9160 isn't - those chips don't support STBC RX. Grr, another thing to add to FreeBSD today. :-) Adrian ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
