Sounds good, I'm squashing this patch:

Did you try to compile?

Not before sending that mail :)

I am not sure if bittiming.h is able to see struct can_priv which is
defined in dev.h.

Nope it doesn't, I moved the can_tdc_is_enabled() to
include/linux/can/dev.h

Ack. It seems to be the only solution…

Moving forward, I will do one more round of tests and send the
patch for iproute2-next (warning, the RFC I sent last month has
some issues, if you wish to test it on your side, please wait).

I will also apply can_tdc_is_enabled() to the etas_es58x driver.

Could you push the recent changes on the testing branch of linux-can-next? It
would be really helpful for me!


Yours sincerely,
Vincent
