2022-01-11linux-cp: Add VPP->Linux synchronizationPim van Pelt1-156/+106
Part 1 -- notes in https://ipng.ch/s/articles/2021/08/13/vpp-2.html Add the ability for VPP to copy out (sync) its state from the dataplane to Linux Interface Pairs, when they exist. Gated by a configuration flag (linux-cp { lcp-sync }), and by a CLI option to toggle on/off, synchronize the following events: - Interface state changes - Interface MTU changes - Interface IPv4/IPv6 address add/deletion In VPP, subints can have any link state and MTU, orthogonal to their phy. In Linux, setting admin-down on a phy forces its children to be down as well. Also, in Linux, MTU of children must not exceed that of the phy. Add a state synchronizer which walks over phy+subints to ensure Linux and VPP end up in the same consistent state. Part 2 -- notes in https://ipng.ch/s/articles/2021/08/15/vpp-3.html Add the ability for VPP to autocreate sub-interfaces of existing Linux Interface pairs. Gated by a configuration flag (linux-cp { lcp-auto-subint }), and by a CLI option to toggle on/off, synchronize the following event: - Sub-interface creation (dot1q, dot1ad, QinQ and QinAD) A few other changes: - Add two functions into netlink.[ch] to delete ip4 and ip6 addresses. - Remove a spurious logline (printing MTU) in netlink.c. - Resolve a TODO around vnet_sw_interface_supports_addressing() Type: improvement Signed-off-by: Pim van Pelt <pim@ipng.nl> Change-Id: I34fc070e80af4013be58d7a8cbf64296cc760e4e Signed-off-by: Pim van Pelt <pim@ipng.nl>
2022-01-06tap: add num_tx_queues APINathan Skrzypczak1-0/+1
This adds a create_tap_v3 api that has a num_tx_queues parameter allowing to create more than num_workers queues, following on multi TX support Type: feature Change-Id: Idce433147e8dd165f842241d6c76e041e1b1c9b8 Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>
2021-11-03linux-cp: Cleanup any existing pairs when an interface is deletedNeale Ranns1-0/+17
Type: fix This only happens when the user deletes the physical before they delete the pair, that's not supoosed to be the case, but don't crash if it is. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I8c2317b360d897775dde23833d04430f88531cbd

2021-09-09linux-cp: Complete interface creation logicPim van Pelt1-44/+243
Linux Control Plane interface creation logic is currently only able to create untagged interfaces, and dot1q VLAN sub-interfaces. This change makes it possible to create dot1ad VLAN sub-ints, and Q-in-AD as well as Q-in-Q sub-interfaces as well. It makes the plugin a bit more robust by catching a few common errors, such as creating an lcp on a sub-interface without its parent having one, and creating an lcp on a sub-interface that is not exact-match. This change has a bunch of smaller improvemnets as well. I documented my work in this post: https://ipng.ch/s/articles/2021/08/12/vpp-1.html It shows that after the change is merged, all VPP interface types now create and operate cleanly as LCP interfaces as well.
