ipv6/exthdrs: strict Pad1 and PadN check
The following tightens the padding check from commit c1412fce7eccae62b4de22494f6ab3ff8a90c0c6 : * Take into account combinations of consecutive Pad1 and PadN. * Catch the corner case of when only padding is present in the header, when the extention header length is 0 (i.e., 8 bytes). In this case, the header would have exactly 6 bytes of padding: +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ : Next Header : Hdr Ext Len=0 : : +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + : Padding (Pad1 or PadN) : +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Signed-off-by: Eldad Zack <eldad@fogrefinery.com> Signed-off-by: David S.
