Add a 64-byte interface "tag" for vhost and tap interfaces
This patch should dispose of spurious objections around interface tag requirements, currently in use as excuses not to support the vpp ML2 plugin. Add "u8 tag[64];" to the sw_interface_details message sent by vpp to control-plane clients. Add u8 tag[64] to the create_vhost_user_if and tap_connect APIs. Added debug CLI to set/show/clear the interface tag on any vnet sw interface. Added the sw_interface_tag_add_del API to set/clear tags on any vnet sw interface. There can be no expectation of "tag atomicity" with respect to physical hardware. Vpp discovers devices before establishing a control-plane connection. This patch upload verifies using the csit oper-161128 branch Change-Id: If8520119e7a586c5ccf0fdda82484ac205622855 Signed-off-by: Dave Barach <dave@barachs.net>
