net 02/05: fib_rules: rename ifindex/ifname/FRA_IFNAME to iifindex/iifname/FRA_IIFNAME

commit 229e77eec406ad68662f18e49fda8b5d366768c5
Author: Patrick McHardy <kaber@trash.net>
Date:   Thu Dec 3 12:05:23 2009 +0100

    net: fib_rules: rename ifindex/ifname/FRA_IFNAME to iifindex/iifname/FRA_IIFNAME

    The next patch will add oif classification, rename interface related members
    and attributes to reflect that they're used for iif classification.
