I have only x86 boxes currently so didn't try to test others. I hope
upstreaming the series through net-next will allow us to find any
fallouts, if any. The changes are very simple, though: they move
code around (the "splitting" part) and eventually change a vlan_present
flag's position in a skbuff structure. Dependency on CPU endianness is
removed by using byte loads for the flag.
