Author: adrian Date: Fri Apr 29 18:53:16 2016 New Revision: 298792 URL: https://svnweb.freebsd.org/changeset/base/298792 Log: [ath] initialise do_ldpc to 0. I .. can't believe I missed this. This showed up because the AP was TX'ing LDPC to an iwm(4) chipset, which didn't advertise LDPC and doesn't /accept/ LDPC. Amusingly, all the two other FreeBSD 11n parts I had tested with (AR9380, Intel 7260) and I completely forgot to test on ye olde hardware. That'll teach me. Tested: * AR9580 (AP) - Intel 7260 (STA), AR9380 (STA), Intel 6205 (STA) Modified: head/sys/dev/ath/if_ath_tx_ht.c Modified: head/sys/dev/ath/if_ath_tx_ht.c ============================================================================== --- head/sys/dev/ath/if_ath_tx_ht.c Fri Apr 29 17:56:16 2016 (r298791) +++ head/sys/dev/ath/if_ath_tx_ht.c Fri Apr 29 18:53:16 2016 (r298792) @@ -237,6 +237,7 @@ ath_tx_rate_fill_rcflags(struct ath_soft * It's a global flag, not a per-try flag, so we clear * it if any of the rate entries aren't 11n. */ + do_ldpc = 0; if ((ni->ni_vap->iv_htcaps & IEEE80211_HTCAP_LDPC) && (ni->ni_htcap & IEEE80211_HTCAP_LDPC)) do_ldpc = 1;
