Re: wireless vs. alignment requirements

Then what about hardware that can't dma ethernet to non-aligned address.
Sky2 hardware breaks if DMA is not 8 byte aligned.  IMHO the IP stack should
handle any alignment, and do the appropriate memove if the CPU requires 
alignment.
Wouldn't that better be handled in the driver rather than having the
test in the generic RX path?
