Scatter-gather should not be enabled if TG3_FLAG_BROKEN_CHECKSUMS is set.  I
would do the following instead:

	if (!(tp->tg3_flags & TG3_FLAG_BROKEN_CHECKSUMS))
		dev->hw_features |= NETIF_F_SG;

TG3_FLAG_BROKEN_CHECKSUMS is set in tg3_get_invariants(), so this code
would need to be placed later than that function call.
