- 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!
