[PATCH iproute2 5.11 2/2] iplink_can: fix format output for details with statistics

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In commit 36e584ad8af6 ("iplink_can: fix format output of clock with
flag -details") from Antonio Borneo a single space has been added to
separate the CAN controller clock value from the numtxqueues value
which is printed in ipaddress.c directly after the CAN info output.

To maintain a common indention every line in the CAN info output now
ends with eight spaces on the next line. While commit 36e584ad8af6
fixed the '-details' option, the '-statistics' option now works too.
