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] [1] https://lore.kernel.org/netdev/CACRpkdYQthFgjwVzHyK3DeYUOdcYyWmdjDPG=Rf9B3VrJ12Rzg@mail.gmail.com/ (local) [2] https://www.wireshark.org/lists/ethereal-dev/200409/msg00090.html [3] https://lore.kernel.org/netdev/20210822193145.1312668-4-alvin@pqrs.dk/ (local) [4] https://lore.kernel.org/netdev/20200708122537.1341307-2-linus.walleij@linaro.org/ (local) Suggested-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Alvin Šipraga <alsi@bang-olufsen.dk> Reviewed-by: Vladimir Oltean <olteanv@gmail.com>
