2022-01-18virtio: remove admin-up flag during interface creationMohsin Kazmi1-3/+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.

2020-09-28virtio: add packet buffering on txMohsin Kazmi1-0/+13
Type: feature This patch adds packet buffering on tx for slow backend which have some jitter/delays in freeing the vrings. There are some limitations to the current design: 1) It only works in poll mode. 2) Atleast 1 rx queue of an interface (with buffering enabled) should be placed on each worker and main thread.

Indirect buffers are used to store indirect descriptors to xmit big packets. This patch moves the indirect buffer allocation from interface creation to device node. Now it allocates or deallocates buffers during tx for chained buffers.
