Back in 2021, support for CAN TDC was added to the kernel in series [1]
and in iproute2 in series [2]. However, the documentation was never
updated.

Hi Vincent

I also don't see anything in man ip-link, nor ip link help. Maybe you
can add this documentation as well?

The help is indeed not directly visible. But I think this is intended
because can is a sub type. The can is simply listed in man ip-link
under the Link types enumeration.

The can help then be obtain by providing that can type:

  $ ip link help can
  Usage: ip link set DEVICE type can
  	[ bitrate BITRATE [ sample-point SAMPLE-POINT] ] |
  	[ tq TQ prop-seg PROP_SEG phase-seg1 PHASE-SEG1
   	  phase-seg2 PHASE-SEG2 [ sjw SJW ] ]
  	[ dbitrate BITRATE [ dsample-point SAMPLE-POINT] ] |
  	[ dtq TQ dprop-seg PROP_SEG dphase-seg1 PHASE-SEG1
   	  dphase-seg2 PHASE-SEG2 [ dsjw SJW ] ]
  	[ tdcv TDCV tdco TDCO tdcf TDCF ]

O.K. Great, thanks for pointing this out.
