Not easily I think. You'd have to get something that has a well-defined
result and see whether padding is present or not. The MAC address might
be good enough (due to len being 24 instead of the expected 20) though.
Thing is that it's really hard to figure out (even at runtime) whether
the kernel and machine are 64 or 32-bits.
I'd think this is a kernel bug and 32-bit userspace should rightfully be
able to expect 32-bit aligned structs, no? Actually fixing it in the
kernel would not be trivial though.
