Subject: net: Replace calls to vrf_dev_get_rth
X-Git-Tag: MMI-PSA29.97-13-9~9125^2~248^2~3
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8e1ed7058b3c79b085cf5b1529698a157499074c;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

net: Replace calls to vrf_dev_get_rth

Replace calls to vrf_dev_get_rth with l3mdev_get_rtable.
The check on the flow flags is handled in the l3mdev operation.
