    Hi

    I am trying to configure my atheros interface to run at OFDM/6Mbps in 11a
    mode, but somehow the interface automatically selects a higher rate
    (according to wicontrol) Are there any thing more than ifconfig media
    OFDM/6Mbps that I need so set to force the interface to use OFDM/6Mbps.

    (Kernel = 5-20040625-CURRENT )

    ath1# ifconfig ath0 10.10.20.1/24 ssid ath101 media OFDM/6Mbps mode 11a
    mediaopt adhoc
    ath1# ifconfig ath0
    ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
            inet 10.10.20.1 netmask 0xffffff00 broadcast 10.10.20.255
            inet6 fe80::205:5dff:fe97:9801%ath0 prefixlen 64 scopeid 0x4
            ether 00:05:5d:97:98:01
            media: IEEE 802.11 Wireless Ethernet OFDM/6Mbps mode 11a <adhoc>
