Description:
For DLink Fiber NIC, Linux 2.4.22 ships with driver version 1.19,
whereas, Linux 2.6.x ship with driver version 1.17.
The following patch upgrades the 2.6.x driver to include changes (and
bug fixes done until 1.19b).
These fixes are (copied from the driver):
1.18 2002/11/07 New tx scheme, adaptive tx_coalesce.
Remove tx_coalesce option.
1.19 2003/12/16 Fix problem parsing the eeprom on big endian
systems. ([email protected])
Disclaimer:
Since I returned my DLink NIC to the store I couldn't test it
thoroughly. It seemed to work just as well as v1.17. However, both
version made the NIC hang after a few minutes.
