[PATCH net-next 1/6] uapi: if_ether: add ETH_P_RTAG for IEEE 802.1CB R-TAG

[Xiaoliang Yang]

The IEEE 802.1CB-2017 standard defines the Redundancy Tag (R-TAG) with
EtherType 0xF1C1. Add ETH_P_RTAG to the kernel's EtherType definitions
so that it can be used by tc classifiers (e.g. cls_flower) and the FRER
tc action for stream identification on the ingress path.
