… neighbors missing on swss restart (sonic-net#1894) Fixes "No buffer space available" issue in lldp during swss restart that casues neighbors to disappear in lldp. #### Why I did it When enough neighbors exit for a switch (>211), LLDP will stop reporting the last few neighbors after swss restarts. This happens even though the tcp packets from those neighbors are still arriving over the ports. This is because the netlink buffer is filled up when the restart occurs and the netlink delete messages are not received by lldp, this leads to the service not including the new neighbors over those ports, which will persist until lldp is restarted: root@sonic:/home/admin# docker exec -it lldp lldpcli show interfaces | grep -A 5 Ethernet520 Interface: Ethernet520 Administrative status: RX and TX Chassis: ChassisID: mac SysName: sonic SysDescr: SONiC Software Version: SONiC.202412_RC Interface: Ethernet520 Administrative status: RX and TX Chassis: ChassisID: mac SysName: sonic SysDescr: SONiC Software Version: SONiC.202412_RC root@sonic:/home/admin# show lldp table | grep "Ethernet520" root@sonic:/home/admin# LLDP buffer errors: syslog.1:2025 Dec 4 14:39:20.084820 sonic WARNING lldp#lldpd[30]: unable to receive netlink answer: No buffer space available syslog.1:2025 Dec 4 14:39:20.0850sonic INFO lldp#supervisord: lldpd 2025-12-04T14:39:20 [WARN/netlink] unable to receive netlink answer: No buffer space available #### How I did it By increasing both the minimum and maximum netlink receive buffer in LLDP I was able to fix this issue #### How to verify it Run: show lldp table systemctl restart swss Check without the change to see if the lldp buffer cannot handle all of the neighbors, then install a version of Sonic with the change to check that the larger buffer fixes this issue. #### Which release branch to backport (provide reason below if selected) - [x] 202412 - [x] 202505 #### Description for the changelog <!-- Write a short (one line) summary that describes the changes in this pull request for inclusion in the changelog: --> Increase lldp netlink buffer limits to fix neighbors missing on swss restart #### A picture of a cute animal (not mandatory but encouraged)

- What I did
The work on Arista 7170 was originally submitted under platform/p4.
Since the platform/barefoot was recently introduced, this is where this platform support needs to go.
For some reasons
sfputilandsensorsnow have wrappers under/usr/local/binthat don't work.The ones under
/usr/binwork properly like on broadcom images.Signed-off-by: Samuel Angebault staphylo@arista.com
- How I did it
Mostly git mv and few edits
- How to verify it
Build and boot the image on a 7170C-64 switch
- Description for the changelog
