Hi, first of all - thank you for your work, i found your project when tried to find why my switch sends 0x8899 packets every second or so. So i found that it is RRCP broadcast message and very intestested if i can convert this switch to the managed one. I already removed cooling plate from the chip and found that it is RTL8370N inside, which seems to be not supported. Some other interesting info:
[root@bunny /home/samm/OpenRRCP/bin]# tcpdump -n -x -vvv -i bce0 broadcast
tcpdump: listening on bce0, link-type EN10MB (Ethernet), capture size 65535 bytes
