This new network driver update includes the contents of the previous one (i.e. QNX4-network_20050408.tar.gz). It provides an update to the Intel 82540 Ethernet driver (i.e. Net.i82540) in order to support newer device IDs. The complete list of supported device IDs can be found in the technote located in /etc/readme/technotes/Net.etheri82540.

Known issues

When Full-Duplex mode is selected (-F) for the Net.via driver, the Media Rate always detects as 0Mb/s FDX.
Workaround: You will have to use the speed option (-s) explicitly. To do this run one of the following commands:
```
Net.via -F -s10
Net.via -F -s100
```
When Full-Duplex mode is selected (-F) for either the Net.ether905 and Net.i82540 drivers, the Media Rate always detects as 100Mb/s FDX.
Workaround: When attached to a 10 Base-T or a 1000 Base-T (Net.i82540 driver only) network, you'll have to use the speed option (-s) explicitly. To do this run one of the following commands:
```
Net.ether905 -F -s10
Net.i82540 -F -s1000
```
