There is now in-kernel support for the EA412/4/9 scsi ethernet adaptors.

Unfortunately, a small bug was introduced when Jason "sanitized" my code
(removed a reliance on a gcc extension), resulting in the stack being
corrupted.

You can apply the small patch attached if you want to give it a try.

The in kernel support has some advantages. There is a noticable
performance improvement, and the bpf code works, which gives you rarp
and tcpdump, for example. The driver supports /dev/se as well as a
network interface.  That means you can use the old etherd program with
se0 instead of uk0.  Don't use it both ways simultaneously though! The
idea of this is to facilitate printing statistics and downloading code
--- functions which are not supported via the ifconfig interface.

Here are some performance figures. Performance may have been limited
by the other end, a sun3 not known as a speed deamon!

Running on pc532:

  spray sun3

    10% dropped packets, 145 pps tx, 130 pps rx 10.9 kB/s

    I presume the dropped packets are the fault of the sun.


  spray -l 1500 sun3

    254.8 kB/sec no dropped packets


  ftp: get /usr/share/misc/termcap /dev/null

    203.2 kB/sec

  ftp: put /usr/share/misc/termcap /dev/null

    227.3 kB/sec


Running on sun3:

  spray pc532

    27.5 kB/s no dropped packets

  spray -l 1500 pc532

    243.0 kB/s no dropped packets


  ftp: get /usr/share/misc/termcap /dev/null

    256.4 kB/s

  ftp: put /usr/share/misc/termcap /dev/null

    184.0 kB/s


Enjoy!

Ian
