An earlier bugfix introduced a dependency on CONFIG_NET_SCH_TAPRIO, but this missed the case of NET_SCH_TAPRIO=m and NET_DSA_SJA1105=y, which still causes a link error: drivers/net/dsa/sja1105/sja1105_tas.o: In function `sja1105_setup_tc_taprio': sja1105_tas.c:(.text+0x5c): undefined reference to `taprio_offload_free' sja1105_tas.c:(.text+0x3b4): undefined reference to `taprio_offload_get' drivers/net/dsa/sja1105/sja1105_tas.o: In function `sja1105_tas_teardown': sja1105_tas.c:(.text+0x6ec): undefined reference to `taprio_offload_free' Change the dependency to only allow selecting the TAS code when it can link against the taprio code.

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.
