Duplexing

Linux Advanced Routing and Traffic Control

The recent thread titled:
working ftp shaping, i think
provided a script example where 100Mbps was specified as the rate for a typical NIC.


If that NIC is connected to a switch, chances are that it runs at 100Mbps in each direction concurrently - duplexed Writing a rule that specifies a 100Mbps rate and thereby a 100Mbps ceil, limits the connection to half the available bandwidth.

I haven't seen anything in tc (not iptables) that addresses direction - inbound or outbound.
Is there a way of writing rules that take duplexing into account so that you end up with 2 virtual devices, each capable of 100Mbps, but the traffic is direction specific?
