[PATCH net-next 1/1] driver: ipvlan: Use NF_IP_PRI_LAST as hook priority instead of INT_MAX

[PATCH net-next 1/1] driver: ipvlan: Use NF_IP_PRI_LAST as hook priority instead of INT_MAX

[fgao]

From: Gao Feng <fgao@ikuai8.com>

It is better to use NF_IP_PRI_LAST instead of INT_MAX as hook priority.
The former is good at readability and easier to maintain.

Sorry, it broke the build.
I add the header file, but forget to commit, so that this patch does
not contain header file

Now I have sent the v2 patch.
