Fix returned tc and hoplimit values for route with IPv6 encapsulation
For a route with IPv6 encapsulation, the traffic class and hop limit
values are interchanged when returned to userspace by the kernel.
For example, see below.
># ip route add 192.168.0.1 dev eth0.2 encap ip6 dst 0x50 tc 0x50 hoplimit 100 table 1000
># ip route show table 1000
192.168.0.1 encap ip6 id 0 src :: dst fe83::1 hoplimit 80 tc 100 dev eth0.2 scope link
