This is the driver for the NXP SJA1105 automotive Ethernet switch
|
family. These are 5-port devices and are managed over an SPI
|
interface. Probing is handled based on OF bindings and so is the
|
linkage to PHYLINK. The driver supports the following revisions:
|
- SJA1105E (Gen. 1, No TT-Ethernet)
|
- SJA1105T (Gen. 1, TT-Ethernet)
|
- SJA1105P (Gen. 2, No SGMII, No TT-Ethernet)
|
- SJA1105Q (Gen. 2, No SGMII, TT-Ethernet)
|
- SJA1105R (Gen. 2, SGMII, No TT-Ethernet)
|
- SJA1105S (Gen. 2, SGMII, TT-Ethernet)

This enables support for the TTEthernet-based egress scheduling
|
engine in the SJA1105 DSA driver, which is controlled using a
|
hardware offload of the tc-tqprio qdisc.

This enables support for flow classification using capable devices
|
(SJA1105T, SJA1105Q, SJA1105S). The following actions are supported:
|
- redirect, trap, drop
|
- time-based ingress policing, via the tc-gate action
|
