Stephen,

Perhaps it is time to fix iproute2 interpretation of kbit/mbit/gbit.

Currently, they are interpreted as powers of 2 (i.e. 10mbit = 
10*1024*1024), which is absolutely incorrect when dealing with networking, 
as line speeds are always interpreted in decimal.

Example: 10Mbit ethernet is 10 000 000 bits/second. Someone who may be 
trying to rate-limit outbound traffic is bound for a surprise when tc's 
10mbit does not match physical line characteristic.

Other examples: 28k modem is 28000 bit/s, 56k is 56000, OC-3 SONET 
(155Mbit) is 155000000 bit/s, etc.  There isn't a technology that is 
quoted with kbits meaning 1024bit/s.
