When using the ethernet port rate limiting (via the swicth chip)
/int eth set name=ether1 bandwidth=
It only offers rates up to 10M, which is a bit limiting 
The hardware on at least some of the models supports a wider range, it according to the datasheet.
“The AR8327 can limit all frames and support rate limits from 32 Kbps to 1 Gbps at 32 Kbps granularity.”
Are there any plans to extend this on the 1G ports ?
