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.

select NET_DSA_TAG_8021Q
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.

Say Y or M if you want to enable support for tagging frames with the
NXP SJA1105 switch family. Both the native tagging protocol (which
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

Say Y or M if you want to enable support for tagging frames at

Arrow SpeedChips XRS700x switches that use a single byte tag trailer.
