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. config NET_DSA_TAG_OCELOT_8021Q tristate "Tag driver for Ocelot family of switches, using VLAN" 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" help Say Y or M if you want to enable support for tagging frames for the Qualcomm Atheros QCA8K switches. config NET_DSA_TAG_LAN9303 tristate "Tag driver for SMSC/Microchip LAN9303 family of switches" help Say Y or M if you want to enable support for tagging frames for the SMSC/Microchip LAN9303 family of switches. config NET_DSA_TAG_SJA1105 tristate "Tag driver for NXP SJA1105 switches" select PACKING help 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 tristate "Tag driver for switches using a trailer tag" help Say Y or M if you want to enable support for tagging frames at with a trailed. e.g. Marvell 88E6060. config NET_DSA_TAG_XRS700X tristate "Tag driver for XRS700x switches" help Say Y or M if you want to enable support for tagging frames for Arrow SpeedChips XRS700x switches that use a single byte tag trailer. endif
