2025-02-26linux-cp: Add support for LACP packetsAkeel Ali1-0/+13
This patch adds support to mirror LACP packets between host and phy. It is needed for the Sonic-VPP project to support LAG and allow Sonic to run LACP in the control plane. The change has 3 parts: (1) Converted lip_punt_node to lip_punt_xc_inline, which now supports the creation of two distinct nodes: lip_punt_node and lip_punt_xc_node. lip_punt_node retains its original punt functionality. lip_punt_xc_node supports both punt and x-connect between host & phy. (2) Add 2 new API (and corresponding CLI) to the linux-cp plugin: (A) lcp_ethertype_enable ("lcp ethertype enable <ethertype>") (B) lcp_ethertype_get ("show lcp ethertype") (3) Add UT to test the new functionality and API/CLI for LACP and LLDP.

2022-01-11linux-cp: Add VPP->Linux synchronizationPim van Pelt1-8/+46
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>
