Merge branch 'add-multicast-filtering-support-for-vlan-interface'
MD Danish Anwar says: ==================== Add Multicast Filtering support for VLAN interface This series adds Multicast filtering support for VLAN interfaces in dual EMAC and HSR offload mode for ICSSG driver. Patch 1/4 - Adds support for VLAN in dual EMAC mode Patch 2/4 - Adds MC filtering support for VLAN in dual EMAC mode Patch 3/4 - Create and export hsr_get_port_ndev() in hsr_device.c Patch 4/4 - Adds MC filtering support for VLAN in HSR mode [1] https://lore.kernel.org/all/[email protected]/ [2] https://lore.kernel.org/all/[email protected]/#t [3] https://lore.kernel.org/all/[email protected]/ v1 https://lore.kernel.org/all/[email protected]/ v2 https://lore.kernel.org/all/[email protected]/ v3 https://lore.kernel.org/all/[email protected]/ ==================== Link: https://patch.msgid.link/[email protected] Signed-off-by: Paolo Abeni <[email protected]>
