Haven't tried jumbos but with the default 1500 MTU this diff breaks

- approx 50% packet loss on Rx, even with simple small pings.
The brgphy diff by itself (i.e. revert the if_bnx.c part) works ok on this
machine but obviously it also needs testing on other nics with jumbo support
using the brgphy, e.g. bge(4) BCM570[0134], I might be able to try it on a
BCM5704C in a bit.
