The revival of the learning-sync bridgeport flag

on YouTube ↗28m

" summary

A converged interface merges an external Ethernet segment with a high‑performance in‑machine hypersockets fabric by running a local Linux bridge, using learning_sync via the switchdev notifiers to mirror firmware FDB events into the bridge FDB, and marking ports as isolated bridgeports with STP off and selective flooding. Implementation adds a small hypersockets driver glue and one generic bridge notification patch, supports many LPARs (86+), preserves performance, learns from firmware, and works with virtualized guests.
