2023-06-27virtio: use fast-path for ethernet-input if possibleStanislav Zaikin1-1/+26
If a frame should be sent to 'ethernet-input' set the ETH_INPUT_FRAME_F_SINGLE_SW_IF_IDX flag. It will force 'ethernet-input' to use a fast-path for such frames. This patch also aligns the behaviour with other input nodes. Type: improvement Change-Id: Icff0fa31204d5304a2ea0a4f4e7bc418dedbfe32 Signed-off-by: Stanislav Zaikin <zstaseg@gmail.com>

2022-01-18virtio: remove admin-up flag during interface creationMohsin Kazmi2-4/+0
Type: fix During the interface creation time, (by default) admin-up flag is locally set for tap and virtio interfaces. While, in VPP the state of these interfaces are still admin-down. User needs to explicitly call 'set interface state <interface-name> up' to admin-up the newly created tap or virtio interface(s) in VPP. So, this behavior is inconsistent. This patch fixes the issue to have consistent behavior for given interface between local and global administration state.
