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)

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
