2018-12-06	net: dsa: Add overhead to tag protocol ops.	Andrew Lunn	1	-0/+1
	Each DSA tag protocol needs to add additional headers to the Ethernet frame in order to direct it towards a specific switch egress port. It must also remove the head from a frame received from a switch. Indicate the maximum size of these headers in the tag protocol ops structure, so the core can take these overheads into account.

2018-09-13	net: dsa: Add Lantiq / Intel GSWIP tag support	Hauke Mehrtens	1	-0/+109
	This handles the tag added by the PMAC on the VRX200 SoC line. The GSWIP uses internally a GSWIP special tag which is located after the Ethernet header. The PMAC which connects the GSWIP to the CPU converts this special tag used by the GSWIP into the PMAC special tag which is added in front of the Ethernet header. This was tested with GSWIP 2.1 found in the VRX200 SoCs, other GSWIP versions use slightly different PMAC special tags.
