canbusload and canfd

[Sven Schuchmann <schuchmann@xxxxxxxxxxxxxxxxx>]

Hi,
I am trying to use the canbusload utility for the first time - ashes on my head :-)

I have an canfd interface configured like this with some traffic:
$ ip -det a s canfd0
3: canfd0: <NOARP,UP,LOWER_UP,ECHO> mtu 72 qdisc pfifo_fast state UP group default qlen 4096
    link/can  promiscuity 0  allmulti 0 minmtu 0 maxmtu 0
    can <BERR-REPORTING,FD> state ERROR-ACTIVE (berr-counter tx 0 rx 0) restart-ms 500
          bitrate 500000 sample-point 0.800
          tq 25 prop-seg 31 phase-seg1 32 phase-seg2 16 sjw 3 brp 1
          mcp251xfd: tseg1 2..256 tseg2 1..128 sjw 1..128 brp 1..256 brp_inc 1
          dbitrate 2000000 dsample-point 0.700
          dtq 25 dprop-seg 6 dphase-seg1 7 dphase-seg2 6 dsjw 4 dbrp 1
          mcp251xfd: dtseg1 1..32 dtseg2 1..16 dsjw 1..16 dbrp 1..256 dbrp_inc 1
          clock 40000000 numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 tso_max_size 65536 tso_max_segs 65535 gro_max_size 65536 parentbus spi parentdev spi0.0

If I do "canbusload canfd0@500000" the output is nothing.
If I do "canbusload canfd0@500000 -r" the output is "canfd0@500000     0       0      0   0%"

Do I need to give a special bitrate for canfd to work?

Regards,

   Sven
