This patch series contains two patches which respectively: 1. factorize the many print_*(PRINT_JSON, ...) and fprintf occurrences in a single print_*(PRINT_ANY, ...) call and fix the signedness while doing that. 2. adds command line support for the TDC in iproute and goes together with below series in the kernel: https://lore.kernel.org/linux-can/20210506111412.1665835-1-mailhol.vincent@xxxxxxxxxx/T/#t For now, I am only sending the kernel mailing list as an RFC. The patch will be sent to iproute maintainers after the kernel patches get accepted. ** Changelog ** >From RFC v1 to RFC v2: * Add an additional patch to the series to fix the issues reported by Stephen Hemminger Ref: https://lore.kernel.org/linux-can/20210506112007.1666738-1-mailhol.vincent@xxxxxxxxxx/T/#t Vincent Mailhol (2): iplink_can: use PRINT_ANY to factorize code and fix signedness iplink_can: add new CAN FD bittiming parameters: Transmitter Delay Compensation (TDC) include/uapi/linux/can/netlink.h | 25 +- ip/iplink_can.c | 402 ++++++++++++++++--------------- 2 files changed, 224 insertions(+), 203 deletions(-) -- 2.26.3
