Subject: fib: Change data type of fib oifname to "ifname"
X-Git-Tag: v1.1.2~79
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=316d99246644268e5e0453afa3ade163fda21d7f;p=thirdparty%2Fnftables.git

fib: Change data type of fib oifname to "ifname"

Change data type of fib oifname from "string" to "ifname", so that it
can be matched against a set of ifnames:

    set x {
            type ifname
    }
    chain y {
            fib saddr oifname @x drop
    }
