H A D | sja1105.h | diff 994d2cbb08ca05e3c1af954ec63a3ae32a862ac5 Tue Aug 17 09:58:47 CDT 2021 Vladimir Oltean <vladimir.oltean@nxp.com> net: dsa: tag_sja1105: be dsa_loop-safe
Add support for tag_sja1105 running on non-sja1105 DSA ports, by making sure that every time we dereference dp->priv, we check the switch's dsa_switch_ops (otherwise we access a struct sja1105_port structure that is in fact something else).
This adds an unconditional build-time dependency between sja1105 being built as module => tag_sja1105 must also be built as module. This was there only for PTP before.
Some sane defaults must also take place when not running on sja1105 hardware. These are:
- sja1105_xmit_tpid: the sja1105 driver uses different VLAN protocols depending on VLAN awareness and switch revision (when an encapsulated VLAN must be sent). Default to 0x8100.
- sja1105_rcv_meta_state_machine: this aggregates PTP frames with their metadata timestamp frames. When running on non-sja1105 hardware, don't do that and accept all frames unmodified.
- sja1105_defer_xmit: calls sja1105_port_deferred_xmit in sja1105_main.c which writes a management route over SPI. When not running on sja1105 hardware, bypass the SPI write and send the frame as-is.
