Support 5787 hardware TSO using a new flag TG3_FLG2_HW_TSO_2.
Since the TSO interface is slightly different and these chips have
finally fixed the 4GB DMA problem and do not have the 40-bit DMA
problem, a new hard_start_xmit is used for these chips. All previous

Or did you take care of that and I missed it somehow?
The 40-bit stuff is handled in another patch, probably still in your

Actually, no I didn't, it's still in my queue sorry.

Ok, so the 40-bit capable chips won't hit the 5780 class code path?
The mask will be set to 40-bit for 5780 class only. In
tg3_start_xmit_dma_bug(), there is a 40-bit DMA address check for 5780
class only and will return 0 for all
