[strongSwan-dev] [PATCH net-next 1/2] include/uapi/linux/xfrm.h: Pack struct xfrm_userpolicy_info

[Fan Du]

Otherwise 64bits kernel has sizeof(struct xfrm_userpolicy_info) 168 bytes,
while 32bits compiled iproute2 see the same structure as 164 bytes, which
leading deficit xfrm policy, in turn broken IPsec connectivity.

Fix this by packing the structure.
