Allows ingress packages on port `p` only when `t`agged, `u`ntagged or `a`ny.
Multiple ports can be given at once as in vlan. When `p` is missing, all ports
are assigned the same mode. CPU port can not be changed.
Use `vlan show` to see current configuration.
Example:
`ingress 1t 2a` -> Set port 1 as tagged input only, set port 2 accepting any frames.
`ingress a` -> Set all ports to accept both tagged and untagged frames (default behaviour).
