This is the driver for the NXP SJA1105 (5-port) and SJA1110 (10-port)
|
||
|
|
automotive Ethernet switch family. These 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)
|
||
|
|
- SJA1110A (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 10 ports)
|
||
|
|
- SJA1110B (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 9 ports)
|
||
|
|
- SJA1110C (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 7 ports)
|

|
- SJA1110D (Gen. 3, SGMII, TT-Ethernet, no 100base-TX PHY, 7 ports)

(SJA1105T, SJA1105Q, SJA1105S). The following actions are supported:
|
||
|
|
- redirect, trap, drop
|

|
|
- time-based ingress policing, via the tc-gate action
