The de425/de434/de435 driver in this distribution is designed to work with the Digital Equipment Corporation series of PCI/EISA ethernet cards (DE425, DE434, DE435) and with all kernels that support PCI. Auto media detection is provided so that the media choice isn't compiled in and is flexible enough to be able to reconfigure on-the-fly. The ability to load this driver as a loadable module has been included, although I don't recommend its use with PCI, since PCI dynamically allocates where the card will go at boot time. The performance we've achieved so far has been measured through the 'ttcp' tool at 1.08MB/s. This measures the total tcp stack performance which includes the card, so don't expect to get much nearer the 1.25MB/s theoretical ethernet rate. ************************************************************************ However there is still a known bug which causes ttcp to hang on transmit (receive is OK), although the adapter/driver continues to function normally for other applications e.g. nfs mounting disks, pinging etc. The cause is under investigation. ************************************************************************ ZYNX cards, which use the PCI DECchip DC21040, are not specifically supported in this driver because a) I have no information on them. b) I cannot test them with the driver. c) Donald Becker's 'tulip.c' driver works with them....well one person says they do and another doesn't, so take your pick! This driver can be made to work with the ZYNX (and may be the SMC) card by setting a compile time flag in linux/drivers/net/CONFIG Enjoy! Dave
