2026-10-01llc: move the type 2 sockets out of treeJakub Kicinski
802.2 LLC is only used in tree by protocols which need the connectionless type 1 subset: STP, which carries the bridge's BPDUs, GARP, which sends its own UI PDUs, and SNAP. The llc2 module on top of the core - the type 2 connection state machine, the type 1 SAP state machine, the station component and the PF_LLC socket family - has no in-kernel users and nobody who can test it; what we get instead is a slow trickle of drive-by fixes. There was a recent patch from Ernestas Kulik indicating potential real life use, but it was new/experimental and that person is not responding to off-list pings. Let LLC2 follow AX.25, hamradio and AppleTalk out of the Linux tree. We will maintain the code at: github.com/linux-netdev/mod-orphan for anyone interested in playing with it. PF_LLC goes in full, both the class two SOCK_STREAM and the class one SOCK_DGRAM half, and so do /proc/net/llc/ and /proc/sys/net/llc/. Note that the kernel also stops answering XID and TEST commands, addressed to a SAP or to the station - those are type 1, but they lived in the module, and they got answered whether or not any socket was open. Nothing in tree asks for them; what the core keeps is SAP registration and the UI path the in-tree users need. Retain the uAPI for now, like we did for AppleTalk. Only the socket ABI half of it is vestigial: STP, GARP, the bridge and openvswitch use the SAP numbers it defines. Cleaning up what the core no longer needs follows in the next patch.

2026-05-26llc: Add SPDX id lines to some llc source filesTim Bird
Most of the lls source files are missing SPDX-License-Identifier lines. Add appropriate IDs to these files, and remove other license info from the header. In once case, leave the existing id line and just remove the license reference text.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
