i386/70832: [re] serious problems with RealTek NIC using re0 driver on Evo N1015v

[Marian Cerny]

I tried to reproduce those problems on FreeBSD 6.2R.

1. I was not able to reproduce the first problem with sporadic hangs at
   boot. However I have not tested the laptop for long enough period.

2. I was not able to reproduce the panic on 'halt -p'. This problem
   seems to be fixed.

3. I WAS able to reproduce the last problem with cvsup & "re0: watchdog
   timeout". But there is a difference in the behaviour. Now when
   watchdog timeouts appear on the screen, the network is still usable.
   The cvsup does not finish successfully. When I tried csup, there also
   was a problem with watchdog timeouts, however the csup doesn't seem
   to block itself and it finishes its job successfully.

The problems are definitely less serious than in FreeBSD 5.2.1R.
