Subject: [PATCH] ether: add IEEE 1722 ethertype - TSN

IEEE 1722 describes AVB (later renamed to TSN - Time Sensitive
Networking), a protocol, encapsualtion and synchronization to utilize
standard networks for audio/video (and later other time-sensitive)
streams.

This standard uses ethertype 0x22F0.

This is a respin of a previous patch ("ether: add AVB frame type
ETH_P_AVB")
