net: ipv6: fix return value of ip6_skb_dst_mtu
Commit 628a5c56 ("[INET]: Add IP(V6)_PMTUDISC_RPOBE") introduced ip6_skb_dst_mtu with return value of signed int which is inconsistent with actually returned values. Also 2 users of this function actually assign its value to unsigned int variable and only __xfrm6_output assigns result of this function to signed variable but actually uses as unsigned in further comparisons and calls. Change this function to return unsigned int value. Fixes: 628a5c56 ("[INET]: Add IP(V6)_PMTUDISC_RPOBE") Reviewed-by:David Ahern <dsahern@kernel.org> Signed-off-by:
