On enslaving event, call mlx5_enslave_rep() API to create, add
this slave representor shadow entry to the slaves list of

its metadata to setup ingress acl metadata header.
On unslaving event, resetting the vport of unslaved representor

When a bond device is created over one or more non uplink representors,

Assuming that this is active-backup lag, the rules should be offloaded

Currently offloading a rule over a tc block shared by multiple
representors fails because an e-switch global hashtable to keep
the mapping from tc cookies to mlx5e flow instances is used, and
tc block sharing offloads the same rule/cookie multiple times,
each time for different representor sharing the tc block.
Changing the implementation and behavior by acknowledging and returning
success if the same rule/cookie is offloaded again to other slave
representor sharing the tc block by setting, checking and comparing
the netdev that added the rule first.

By default, e-switch vport's egress acl just forward packets to its
counterpart NIC vport using existing egress acl table.
During port failover in bonding scenario where two VFs representors
are bonded, the egress acl forward-to-vport rule will be added to
the existing egress acl table of e-switch vport of passive/inactive
slave representor to forward packets to other NIC vport ie. the active
slave representor's NIC vport to handle egress "failover" traffic.
Enable egress acl and have APIs to create and destroy egress acl
forward-to-vport rule and group.

As explained in other commits before (b9cd75e66895 and 87b0f983f66f),
ocelot switches have a single egress-untagged VLAN per port, and the
driver would deny adding a second one while an egress-untagged VLAN
already exists.
But on the CPU port (where the VLAN configuration is implicit, because
there is no net device for the bridge to control), the DSA core attempts
to add a VLAN using the same flags as were used for the front-panel
port. This would make adding any untagged VLAN fail due to the CPU port
rejecting the configuration:
bridge vlan add dev swp0 vid 100 pvid untagged
[ 1865.854253] mscc_felix 0000:00:00.5: Port already has a native VLAN: 1
[ 1865.860824] mscc_felix 0000:00:00.5: Failed to add VLAN 100 to port 5: -16
(note that port 5 is the CPU port and not the front-panel swp0).
So this hardware will send all VLANs as tagged towards the CPU.

The ocelot core library is written with the idea in mind that the VLAN
table is populated by the bridge. Otherwise, not even a sane default
pvid is provided: in standalone mode, the default pvid is 0, and the
core expects the bridge layer to change it to 1.
So without this patch, the VLAN table is completely empty at the end of
the commands below, and traffic is broken as a result:
ip link add dev br0 type bridge vlan_filtering 0 && ip link set dev br0 up
for eth in $(ls /sys/bus/pci/devices/0000\:00\:00.5/net/); do
ip link set dev $eth master br0
