Re: [PATCH] cangen: Support RTR frames with random or increment CAN IDs

[Oliver Hartkopp <oliver.hartkopp@volkswagen.de>]

Hello Alexander,

just yesterday evening i was pondering about making the canfd branch of the
can-utils the master branch ...

Due to added the CAN FD possibilities is also cleaned up the RTR sending
which can be done randomly now too.

See the commit log at
https://gitorious.org/linux-can/can-utils/commit/51c57c8445d5a0faef73f32fc9f5b772d4fde939

Please check out the canfd branch and see if cangen meets your requirements.

The same with 'candump' ...
There's a new '-x' option which prints extra message infos: RX/TX BRS ESI

Best regards,
Oliver
