[netdrivers] RE: D-Link DFE-580TX

[Peter Schobel]

Hi,

we are using the sundance.c driver with Fedora Core 2 kernel 2.6.8-1.521

some modifications that we made to the driver greatly reduced the number
of transmit timed out errors although these errors still occur when
traffic levels get high - but its almost tolerable

The modification:

diff 268sundance.c sundance.c

> #define TX_RING_SIZE  64  // lxin: increase tx ring size, may
decrease/waste available memory
