Subject: [PATCH net-next 1/6] ether: add EtherType for proprietary Realtek protocols
Date: Tue, 12 Oct 2021 14:35:50 +0200 [thread overview]
Message-ID: <20211012123557.3547280-2-alvin@pqrs.dk> (raw)
In-Reply-To: <20211012123557.3547280-1-alvin@pqrs.dk>
From: Alvin Šipraga <alsi@bang-olufsen.dk>
Add a new EtherType ETH_P_REALTEK to the if_ether.h uapi header. The
EtherType 0x8899 is used in a number of different protocols from Realtek
Semiconductor Corp [1], so no general assumptions should be made when
trying to decode such packets. Observed protocols include:
0x1 - Realtek Remote Control protocol [2]
0x2 - Echo protocol [2]
0x3 - Loop detection protocol [2]
0x4 - RTL8365MB 4- and 8-byte switch CPU tag protocols [3]
0x9 - RTL8306 switch CPU tag protocol [4]
0xA - RTL8366RB switch CPU tag protocol [4]
