From: David Ahern Date: Wed, 30 Sep 2015 03:07:13 +0000 (-0700) Subject: net: Replace vrf_master_ifindex{, _rcu} with l3mdev equivalents X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=385add906b6155e8bc64035ad56fb8ccfef925f7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git net: Replace vrf_master_ifindex{, _rcu} with l3mdev equivalents Replace calls to vrf_master_ifindex_rcu and vrf_master_ifindex with either l3mdev_master_ifindex_rcu or l3mdev_master_ifindex. The pattern: oif = vrf_master_ifindex(dev) ? : dev->ifindex; is replaced with oif = l3mdev_fib_oif(dev); And remove the now unused vrf macros. Signed-off-by: David Ahern Signed-off-by: David S.
