Have you verified that all accesses are __aligned(2) ?

If so, please state that in the patch description.

i.e.: is pattrib->ra __aligned(2) ?


Hi Joe,

I looked at the function comment for is_multicast_ether_addr in etherdevice.h.
There is not mentioned that __aligned(2) is required. If it is, I will check.

So, is it required although it's not mentioned for is_multicast_ether_addr?
