	select VLAN_8021Q
	help
	  Unlike the other tagging protocols, the 802.1Q config option simply
	  provides helpers for other tagging implementations that might rely on
	  VLAN in one way or another. It is not a complete solution.

	  Drivers which use these helpers should select this as dependency.

	  Say Y or M if you want to enable NPI tagging for the Ocelot switches
	  (VSC7511, VSC7512, VSC7513, VSC7514, VSC9953, VSC9959). In this mode,
	  the frames over the Ethernet CPU port are prepended with a
	  hardware-defined injection/extraction frame header.  Flow control
	  (PAUSE frames) over the CPU port is not supported when operating in
	  this mode.

	help
	  Say Y or M if you want to enable support for tagging frames with a
	  custom VLAN-based header. Frames that require timestamping, such as
	  PTP, are not delivered over Ethernet but over register-based MMIO.
	  Flow control over the CPU port is functional in this mode. When using
	  this mode, less TCAM resources (VCAP IS1, IS2, ES0) are available for
	  use with tc-flower.

config NET_DSA_TAG_QCA
	tristate "Tag driver for Qualcomm Atheros QCA8K switches"

	  is only for link-local traffic) as well as non-native tagging (based
	  on a custom 802.1Q VLAN header) are available.

config NET_DSA_TAG_TRAILER
	tristate "Tag driver for switches using a trailer tag"
	help
	  Say Y or M if you want to enable support for tagging frames at
