ipv6/send/patches/003-keysig_8bytes_alignment.patch

   1 This patch aligns the structure describing the RSA signature
   2 option to 8 bytes. Before that, send was padding with N bytes
   3 (4 on 32-bits architectures) using a cast in sendd/proto_sig.c :
   4
   5         so = (struct snd_opt_sig *)(nd_so);
   6
   7 which would align to the number of bytes representing a pointer
   8 on your architecture.
