9 tristate "Distributed Switch Architecture"
10 depends on HAVE_NET_DSA
11 depends on BRIDGE || BRIDGE=n
17 Say Y if you want to enable support for the hardware switches supported
18 by the Distributed Switch Architecture.
23 config NET_DSA_TAG_8021Q
27 Unlike the other tagging protocols, the 802.1Q config option simply
28 provides helpers for other tagging implementations that might rely on
29 VLAN in one way or another. It is not a complete solution.
31 Drivers which use these helpers should select this as dependency.
33 config NET_DSA_TAG_AR9331
34 tristate "Tag driver for Atheros AR9331 SoC with built-in switch"
36 Say Y or M if you want to enable support for tagging frames for
37 the Atheros AR9331 SoC with built-in switch.

43 config NET_DSA_TAG_BRCM
44 tristate "Tag driver for Broadcom switches using in-frame headers"
45 select NET_DSA_TAG_BRCM_COMMON
47 Say Y if you want to enable support for tagging frames for the
48 Broadcom switches which place the tag after the MAC source address.
51 config NET_DSA_TAG_BRCM_PREPEND
52 tristate "Tag driver for Broadcom switches using prepended headers"
53 select NET_DSA_TAG_BRCM_COMMON
55 Say Y if you want to enable support for tagging frames for the
56 Broadcom switches which places the tag before the Ethernet header
59 config NET_DSA_TAG_HELLCREEK
60 tristate "Tag driver for Hirschmann Hellcreek TSN switches"
62 Say Y or M if you want to enable support for tagging frames
63 for the Hirschmann Hellcreek TSN switches.
65 config NET_DSA_TAG_GSWIP
66 tristate "Tag driver for Lantiq / Intel GSWIP switches"
68 Say Y or M if you want to enable support for tagging frames for the
69 Lantiq / Intel GSWIP switches.
71 config NET_DSA_TAG_DSA_COMMON
74 config NET_DSA_TAG_DSA
75 tristate "Tag driver for Marvell switches using DSA headers"
76 select NET_DSA_TAG_DSA_COMMON
78 Say Y or M if you want to enable support for tagging frames for the
79 Marvell switches which use DSA headers.
81 config NET_DSA_TAG_EDSA
82 tristate "Tag driver for Marvell switches using EtherType DSA headers"
83 select NET_DSA_TAG_DSA_COMMON
85 Say Y or M if you want to enable support for tagging frames for the
86 Marvell switches which use EtherType DSA headers.

97 Say Y if you want to enable support for tagging frames for the
98 Microchip 8795/9477/9893 families of switches.
100 config NET_DSA_TAG_RTL4_A
101 tristate "Tag driver for Realtek 4 byte protocol A tags"
103 Say Y or M if you want to enable support for tagging frames for the
104 Realtek switches with 4 byte protocol A tags, sich as found in
105 the Realtek RTL8366RB.
107 config NET_DSA_TAG_OCELOT
108 tristate "Tag driver for Ocelot family of switches, using NPI port"
111 Say Y or M if you want to enable NPI tagging for the Ocelot switches
112 (VSC7511, VSC7512, VSC7513, VSC7514, VSC9953, VSC9959). In this mode,
113 the frames over the Ethernet CPU port are prepended with a
114 hardware-defined injection/extraction frame header. Flow control
115 (PAUSE frames) over the CPU port is not supported when operating in
118 config NET_DSA_TAG_OCELOT_8021Q
119 tristate "Tag driver for Ocelot family of switches, using VLAN"
120 select NET_DSA_TAG_8021Q
122 Say Y or M if you want to enable support for tagging frames with a
123 custom VLAN-based header. Frames that require timestamping, such as
124 PTP, are not delivered over Ethernet but over register-based MMIO.
125 Flow control over the CPU port is functional in this mode. When using
126 this mode, less TCAM resources (VCAP IS1, IS2, ES0) are available for
129 config NET_DSA_TAG_QCA
130 tristate "Tag driver for Qualcomm Atheros QCA8K switches"
132 Say Y or M if you want to enable support for tagging frames for
133 the Qualcomm Atheros QCA8K switches.

138 Say Y or M if you want to enable support for tagging frames for the
139 SMSC/Microchip LAN9303 family of switches.
141 config NET_DSA_TAG_SJA1105
142 tristate "Tag driver for NXP SJA1105 switches"
143 select NET_DSA_TAG_8021Q
146 Say Y or M if you want to enable support for tagging frames with the
147 NXP SJA1105 switch family. Both the native tagging protocol (which
148 is only for link-local traffic) as well as non-native tagging (based
149 on a custom 802.1Q VLAN header) are available.
151 config NET_DSA_TAG_TRAILER
152 tristate "Tag driver for switches using a trailer tag"
154 Say Y or M if you want to enable support for tagging frames at
155 with a trailed. e.g. Marvell 88E6060.
157 config NET_DSA_TAG_XRS700X
158 tristate "Tag driver for XRS700x switches"
160 Say Y or M if you want to enable support for tagging frames for
161 Arrow SpeedChips XRS700x switches that use a single byte tag trailer.
