Subject: ipv6: use SKB_DROP_REASON_IP_OUTNOROUTES in inet6_csk_xmit()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4a64f97325776cdab5ec35c0e78b2bdd1468d90a;p=thirdparty%2Flinux.git

ipv6: use SKB_DROP_REASON_IP_OUTNOROUTES in inet6_csk_xmit()

Replace a bare kfree_skb() with a modern sk_skb_reason_drop() call,
and provide IP_OUTNOROUTES drop reason.
