ether_addr_equal_unaligned is only useful for
code symmetry when some uses are known to be
ether_addr_equal.

At least one of these conversions could/should be
ether_addr_equal.

Have you checked or did you just do a global
s/memcpy/ether_addr_equal_unaligned/ ?

I looked at this one, both are __aligned(2)
I didn't look at any others.
