0011 This is the driver for the NXP SJA1105 (5-port) and SJA1110 (10-port)
0012 automotive Ethernet switch family. These are managed over an SPI
0013 interface. Probing is handled based on OF bindings and so is the
0014 linkage to PHYLINK. The driver supports the following revisions:
0015 - SJA1105E (Gen. 1, No TT-Ethernet)
0016 - SJA1105T (Gen. 1, TT-Ethernet)
0017 - SJA1105P (Gen. 2, No SGMII, No TT-Ethernet)
0018 - SJA1105Q (Gen. 2, No SGMII, TT-Ethernet)
0019 - SJA1105R (Gen. 2, SGMII, No TT-Ethernet)
0020 - SJA1105S (Gen. 2, SGMII, TT-Ethernet)
0021 - SJA1110A (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 10 ports)
0022 - SJA1110B (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 9 ports)
0023 - SJA1110C (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 7 ports)
0024 - SJA1110D (Gen. 3, SGMII, TT-Ethernet, no 100base-TX PHY, 7 ports)

0048 This enables support for flow classification using capable devices
0049 (SJA1105T, SJA1105Q, SJA1105S). The following actions are supported:
0050 - redirect, trap, drop
0051 - time-based ingress policing, via the tc-gate action
