I'm sorry about the world "master". I only wanted to say the interface
which the current BSSID is derived from ;)...

Here is my test bed:

PC1:

ath0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu
1500
        ssid ADHOC nwkey 0xaaaaaaaaaaaaaaaaaaaaaaaaaa
        powersave off
        bssid 02:09:5b:a3:22:c9 chan 36

        media: IEEE802.11 OFDM6 mode 11a adhoc (autoselect mode 11a
adhoc)
        status: active
        inet6 fe80::209:5bff:fea3:22c2%ath0 prefixlen 64 scopeid 0x4
        inet6 2001:660:10c::2 prefixlen 64


PC2:

ath0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu
1500
        ssid ADHOC nwkey 0xaaaaaaaaaaaaaaaaaaaaaaaaaa
        powersave off
        bssid 02:09:5b:a3:22:c9 chan 36
        address: 00:09:5b:a3:22:c9
        media: IEEE802.11 OFDM6 mode 11a adhoc (autoselect mode 11a
adhoc)
        status: active
        inet6 fe80::209:5bff:fea3:22c9%ath0 prefixlen 64 scopeid 0x9
        inet6 2001:660:10c::3 prefixlen 64


I've called "master" PC2 because the actual bssid was derived from its
mac address... 

So here is the "wiconfig ath0" result just after a reboot...

You can see that the TX rate (actual speed) is different for both PCs
(24 vs 54).

When in debug mode, I can even see "ath0: bugus xmit rate 0x0" on PC2

If I do "ifconfig ath0 down" and "ifconfig ath0 up" on PC2 I get the
following "wiconfig ath0" on PC2:

The TX rate (actual speed) is now the same as on the first PC (24). It
is however strange that media OFDM6 uses 24Mbps rate, but both PCs are
able to ping each other :).

I'm still investigating about "no buffer space". I'll keep you in touch
when I discover something...
