2025-01-29sflow: replace VAPI with DLAPIPim van Pelt1-5/+0
Remove the requirement to coordinate between linux-cp and sflow at build time via cmake. Also, remove 350 lines of awkward thread-forking VAPI code. Replace it with a dynamically retrieved function from the linux-cp plugin, called lcp_itf_pair_get_vif_index_by_phy(). Remove build inhibit based on Netlink headers, and only inhibit the build for FreeBSD. This plugin can now run regardless of Linux CP being built or loaded, and then return VPP ifIndex numbers instead. Also, fix a flaky test where non-ephemeral source ports throw off packet captures.

2025-01-20sflow: initial checkinPim van Pelt1-0/+523
This is an sFlow dataplane plugin that can sample 1-in-N packets from device-input, copying them to a FIFO queue and servicing that queue from a main process which formats them as Netlink PSAMPLEs, to be picked up by a popular sidecar agent called host-sflow.
