Subject: [PATCH net-next 10/12] ice: implement bridge port vlan
From: Michal Swiatkowski <michal.swiatkowski@...ux.intel.com>
Port VLAN in this case means push and pop VLAN action on specific vid.
There are a few limitation in hardware:
- push and pop can't be used separately
- if port VLAN is used there can't be any trunk VLANs, because pop
action is done on all traffic received by VSI in port VLAN mode
- port VLAN mode on uplink port isn't supported
Reflect these limitations in code using dev_info to inform the user
about unsupported configuration.
In bridge mode there is a need to configure port vlan without resetting
VFs. To do that implement ice_port_vlan_on/off() functions. They are
only configuring correct vlan_ops to allow setting port vlan.
We also need to clear port vlan without resetting the VF which is not
supported right now. Change it by implementing clear_port_vlan ops.
As previous VLAN configuration isn't always the same, store current
config while creating port vlan and restore it in clear function.
Configuration steps:
- configure switchdev with bridge
- #bridge vlan add dev eth0 vid 120 pvid untagged
- #bridge vlan add dev eth1 vid 120 pvid untagged
- ping from VF0 to VF1
