11 This is the driver for the NXP SJA1105 (5-port) and SJA1110 (10-port)
12 automotive Ethernet switch family. These are managed over an SPI
13 interface. Probing is handled based on OF bindings and so is the
14 linkage to PHYLINK. The driver supports the following revisions:
15 - SJA1105E (Gen. 1, No TT-Ethernet)
16 - SJA1105T (Gen. 1, TT-Ethernet)
17 - SJA1105P (Gen. 2, No SGMII, No TT-Ethernet)
18 - SJA1105Q (Gen. 2, No SGMII, TT-Ethernet)
19 - SJA1105R (Gen. 2, SGMII, No TT-Ethernet)
20 - SJA1105S (Gen. 2, SGMII, TT-Ethernet)
21 - SJA1110A (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 10 ports)
22 - SJA1110B (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 9 ports)
23 - SJA1110C (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 7 ports)
24 - SJA1110D (Gen. 3, SGMII, TT-Ethernet, no 100base-TX PHY, 7 ports)

28 depends on NET_DSA_SJA1105
29 depends on PTP_1588_CLOCK
31 This enables support for timestamping and PTP clock manipulations in
32 the SJA1105 DSA driver.

37 depends on NET_SCH_TAPRIO=y || NET_DSA_SJA1105=m
38 depends on NET_DSA_SJA1105_PTP
40 This enables support for the TTEthernet-based egress scheduling
41 engine in the SJA1105 DSA driver, which is controlled using a
42 hardware offload of the tc-tqprio qdisc.
44 config NET_DSA_SJA1105_VL
45 bool "Support for Virtual Links on NXP SJA1105"
46 depends on NET_DSA_SJA1105_TAS
48 This enables support for flow classification using capable devices
49 (SJA1105T, SJA1105Q, SJA1105S). The following actions are supported:
50 - redirect, trap, drop
51 - time-based ingress policing, via the tc-gate action
