Just to say: this is good news for 8.x, particularly for VIMAGE.

Losing the Giant lock from the network drivers will resolve the 
possibility of a number of race conditions occurring in the network 
stack, which are particularly noticeable with VIMAGE, due to how 
protocol domains attach within vimages..

I'd expect that ongoing work could benefit by eliminating some use of 
netisrs, however, it might be a good idea to retain those for a little 
longer to make backporting to 7.x easier.

thanks,
BMS
