Multichannel support

Hey,

I was wondering if this implementation supports multi-channeling?
When only one channel is used, everything works fine.
I have tried this with two PCs :
One mesh-point mode wireless card on each of the PCs and everything is
working as it should. The stations see each other and I can ping them. When
I set up a new wireless card on one of the PCs also in mesh-point mode but
using a different channel then I cannot ping the PCs any more.
Therefore, it seems to me that multichannel is not yet supported. Am I right
or am I doing something wrong?

Also another interesting thing is that although I patched my Wireshark
(1.3.2 with patch from http://www.o11s.org site ). I can not see the new IEs
in the captured frames. I have downloaded a sample mesh capture file from
wireshark website and there I can see beacon frames, so I guess that
Wireshark was pathced and built correctly. (no errors during build))
But when I capture my ping I do not see the PREQ and PREP parts for
instance. In fact I do not see any mesh specific fields in the frames. Am am
expecting to see the PREQ and PREP frames before the pings ICMP frames are
actually transmitted since the forwarding table is empty (checked with mpath
dump). The only thing I see are regular ARP frames used to match IPs to MAC
addresses.
Do you have any ideas what am I doing wrong?

Thanks a lot,
  Attila
