Subject: [PATCH iproute2 3/3] xfrm_{state,policy}: Allow to deleteall
 polices/states with marks

Using 'ip deleteall' with policies that have marks, fails unless you
eplicitely specify the mark values. This is very uncomfortable when
bulk-deleting policies and states. With this patch all relevant states
and policies are wiped by 'ip deleteall' regardless of their mark
values.
