This seems rather obscure - I mean, it's not obvious to driver authors that should be the case. Would it not be better to make this a little more obvious somehow? Maybe __aligned(2) against mac_addr? Or maybe have a debugging check for it?That'd be for David Miller (cc'd). I believe he's argued in the past that any alignment check for mac addresses was unnecessary. For all I know it really might not matter because pasemi can successfully dereference a ushort against an odd char pointer. I just noticed it and thought it'd be better moved.As can ARM too for years now - either in hardware or via fixup for kernel code.
But probably not a good idea if it's done in a fast path.
