testing required: ti(4) NIC

[Gleb Smirnoff]

  Dear colleagues,

  together with Pyun we have prepared a patch, that should make
ti(4) interface announce its link status to upper network
layers. This is important for some network protocols, e.g.
routing daemons and CARP. The patch also fixes driver to
change if_baudrate status when link speed changes. This is important
for correct operation of bsnmpd.

  We need to find a volunteer, who can spend some time and test the
patch. If you can help, please reply. The patch is attached to
this message.
