my mistake, sorry for that confusion.

the fake hangs on 82562/6 devices occur on 10mbit link only. You can check in the
code for a line that says:

	adapter->tx_timeout_factor = 8;

change that number to 16 to cope with the problem on 10mbit link partners. However
this won't fix the issue on 100mbit partners and we need to investigate that if
that is the case.
