        src/sys/netmpls [netbsd-7]: mpls_ttl.c

Log Message:
Pull up following revision(s) (requested by maxv in ticket #1571):
        sys/net/if_mpls.c: 1.31-1.33 via patch
        sys/netmpls/mpls_ttl.c: 1.9
Style, and fix several bugs:
 - ip4_check(), mpls_unlabel_inet() and mpls_unlabel_inet6() perform
   pullups, so we need to pass the updated pointers back
 - in mpls_lse() the route is not always freed
Looks a little better now.

Kick MPLS packets earlier.

Several changes:
 * Declare TRIM_LABEL as a function.
 * In mpls_unlabel_inet, copy the label locally. It's not incorrect to
   keep a pointer on the mbuf, but it's bug-friendly.
 * In mpls_label_inetX, fix the length check. Meanwhile add an XXX: we
   just want to make sure that m_copydata won't fail, but if we were
   guaranteed that m has M_PKTHDR set, we could simply check the length
   against m->m_pkthdr.len.
