- Change to the same transmit scheme as the PNIC driver. - Dynamically set the cache alignment, and set burst size the same as the PNIC driver in mx_init(). - Enable 'store and forward' mode by default. This is the slowest option and it does reduce 100Mbps performance somewhat, but it's the most reliable setting I can find. I'm more interested in having the driver work reliably than trying to squeeze the best performance out of it. The reason I'm doing this is that on *some* systems you may see a lot of transmit underruns (which I can't explain: these are *fast* test systems) and these errors seem to cause unusual and decidedly non-tulip-like behavior. In normal 10Mbps mode, performance is fine (you can easily saturate a 10Mbps link). Also tweak some of the other drivers: - Increase the size of the TX ring for the Winbond, ASIX, VIA Rhine and PNIC drivers. - Set a larger value for ifq_maxlen in the ThunderLAN driver. The setting of TL_TX_LIST_CNT - 1 is too low (the ThunderLAN driver only allocates 20 transmit descriptors, and I don't want to fiddle with that now because the ThunderLAN's descriptor structure is an oddball size compared to the others).
