>Description:
Running ifconfig -v wlan1 makes:
        sturbo  ucast NONE    mgmt  6 Mb/s mcast  6 Mb/s maxretry 6
        11na    ucast NONE    mgmt 12 MCS  mcast 12 MCS  maxretry 6
        11ng    ucast NONE    mgmt  2 MCS  mcast  2 MCS  maxretry 6

I think that it's incorrect. 12MCS needs 2 spatial stream and what is with cards which support only one?

Something in this subject is mentioned in line 1608 sys/net80211/ieee80211.c
   1608 >.......>......./* NB: 12 is ambiguous, it will be treated as an MCS */
