Yes... did you have a chance to test the vlan stuff on LE machines (x86) ? did it work with the BE swapping you were doing ? I've purposedly removed in my patches the hardware side swapping of the descriptors, as I explained, thus making the hardware react the same on ppc and x86. Thus we need the exact same swapping macros on both platforms). I know pretty much nothing about vlan so I'm not too much about trying to check that right now :) Also, there is still the hw checksum issue .... I need to verify what's up there, it might be a swapping problem as well... or not. Can you send me your latest patch set so I can work from there ? Cheers, Ben
