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.

That looks bogus.  If this is about 'speed' attribute
consider removing fmt_udec and replace the printf specifier
of speed_show with fmt_dec instead.
