Yes, you are right - now I checked with octe0 connected to 100 megabit
switch and it initializes correctly when booting. When I plug gigabit
card now instead, it does not work - no communication on interface.
Even if I do ifconfig octe down/ifconfig octe up, it does not
transmit/receive packets. So I think problem is phy link speed change
on live system. Reboot in this case is a big hackish 'workaround' for
now - good for tests, not yet fully for real work (but if you know
there will be no link speed change it is OK).
