This driver has been upgraded to include generic DECchip support through the
use of the on-board SROM that is found on all DECchip cards except for the
DC21040. The driver will work with the following set of cards and probably
more:
KINGSTON
Linksys
ZNYX342
SMC8432
SMC9332 (w/new SROM)
ZNYX31[45]
DIGITAL EtherWORKS PCI/EISA (DE425, DE434, DE435, DE450, DE500)
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 and
will now load (and unload) as many DECchip cards as it can find and
configure with just one invocation of 'insmod'.
The performance we've achieved so far has been measured through the 'ttcp'
tool at 1.06MB/s for TCP and 1.17MB/s for UDP. This measures the total
stack performance which includes the card, so don't expect to get much
nearer the 1.25MB/s theoretical ethernet rate.
TCP UDP
TX RX TX RX
DE425 1030k 997k 1170k 1128k (EISA on a Dell 433DE)
DE434 1063k 995k 1170k 1125k (PCI: DECpc XL 466d2)
DE435 1063k 995k 1170k 1125k (PCI: DECpc XL 466d2)
DE500 1063k 998k 1170k 1125k in 10Mb/s mode (PCI: DECpc XL 466d2)
All values are typical (in kBytes/sec) from a sample of 4 for each
measurement. Their error is approx +/-20k on a quiet (private) network and
also depend on what load the CPU has, CPU speed etc.
I've had reports that Alphas can get 80+Mb/s when using 100BASE-TX and
similar figures for 133MHz Pentium Pros.
Enjoy!
