Subject: openvswitch: Pass net into ovs_vport_output
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=188515fbc6b18e6bc6f2fa4629f1a77308197371;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

openvswitch: Pass net into ovs_vport_output

When struct net starts being passed through the ipv4 and ipv6 fragment
routines ovs_vport_output will need to take a net parameter.
Prepare ovs_vport_output before that is needed and introduce
ovs_vport_output_skk for the call sites that still need the old
calling conventions.
