sometimes packets like this one are sent and
cause change speed and break IrLAP link.
They are not seen by irdadump.
There is "SMB%" and Samba domain names in them.

in toshoboe_hard_xmit, I have done this:

if (!cb->magic) {
  _dumpbufs(skb->data,skb->len,'>');
  cb->magic = LAP_MAGIC;
  cb->speed = self->speed;
  }

with this, the SMB broadcast is transmitted with the current speed,
and no mtt required. Connection is not broken. I am satisfied.
I have found a better solution tothis, adding in the /etc/smb.conf :
    interfaces = lo eth0
 bind interfaces only = True

But are there any other packets that may break IrLAP link?
Is it good to do speed changes that are not cotrolled by IrLAP?
