>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
