This series adds VLAN support to HSR framework. This series also adds VLAN support to HSR mode of ICSSG Ethernet driver.
Changes from v2 to v3: *) Modified hsr_ndo_vlan_rx_add_vid() to handle arbitrary HSR_PT_SLAVE_A, HSR_PT_SLAVE_B order and skip INTERLINK port in patch 2/4 as suggested by Paolo Abeni pabeni@redhat.com *) Removed handling of HSR_PT_MASTER in hsr_ndo_vlan_rx_kill_vid() as MASTER and INTERLINK port will be ignored anyway in the default switch case as suggested by Paolo Abeni pabeni@redhat.com *) Modified the selftest in patch 4/4 to use vlan by default. The test will check the exposed feature `vlan-challenged` and if vlan is not supported, skip the vlan test as suggested by Paolo Abeni pabeni@redhat.com. Test logs can be found at [1]
Changes from v1 to v2: *) Added patch 4/4 to add test script related to VLAN in HSR as asked by Lukasz Majewski lukma@denx.de

This patch adds support for VLAN ctag based filtering at slave devices. The slave ethernet device may be capable of filtering ethernet packets based on VLAN ID. This requires that when the VLAN interface is created over an HSR/PRP interface, it passes the VID information to the associated slave ethernet devices so that it updates the hardware filters to filter ethernet frames based on VID. This patch adds the required functions to propagate the vid information to the slave devices.

Add support for VLAN addition/deletion in HSR mode. In HSR mode, even if the host port is not a member of the VLAN domain, the slave ports should simply forward the frames. So allow forwarding of all VLAN frames in HSR mode.
