Two comments:

1) Never force 10/100 full duplex on the NIC, it is _usually_ wrong.

2) I wonder why tg3 driver isn't being used?  Folks normally report
higher performance with tg3 versus bcm5700.  Our bug reporters are
showing that you simply cannot get wire speed with bcm5700 in many
situations, where tg3 does do wire speed.
