- Configuring the switch over SPI cannot apparently be done from this ndo_setup_tc callback because it runs in atomic context. I also have some downstream patches to offload tc clsact matchall with mirred action, but in that case it looks like the atomic context restriction does not apply.There have been similar problems in the past. We can probably have the DSA layer turn it into a notifier. Look at the dsa_port_mdb_* functions for example. Andrew
Ok, thanks. I thought the dsa_port_notify functions are just to be called from switchdev. I'm still not sure I fully understand, but I'll try to switch to that in v2 and see what happens. -Vladimir
