| |
Otherwise 4294967295 (MBit/s) (-1) will be printed when there is no link. Documentation/ABI/testing/sysfs-class-net does not state if this shall be signed or unsigned. Also remove the now unused variable fmt_udec.
Signed-off-by: Alexander Stein <alexander.stein@systec-electronic.com> --- Changes in v2: * Switch the format specifier instead of changing it * Remove the now unused variable
