drivers/net/vsc9953: Add commands for VLAN ingress filtering
The command: ethsw [port <port_no>] ingress filtering { [help] | show | enable | disable } - enable/disable VLAN ingress filtering on port can be used to enable/disable/show VLAN ingress filtering on a port. This command has also been added to the ethsw generic parser from common/cmd_ethsw.c Signed-off-by: Johnson Leung <johnson.leung@freescale.com> Signed-off-by: Codrin Ciubotariu <codrin.ciubotariu@freescale.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: York Sun <yorksun@freescale.com>
