Hello all

For those of you who have a Broadcom 4401 10/100 Ethernet (not gigabit) can
you please try the driver at
http://people.freebsd.org/~dmlb/bcm-0306291936.tar.gz. Untar it, and you
should have sys/dev/bcm/* and
sys/modules/bcm/Makefile. Put these into /sys then
    cd /sys/modules/bcm
    make
    make test
then use the interface.

If you encounter wierdness, please reboot with -v, and reload the module and
recreate the wierdness. Then send me the dmesg output.

The driver is sub-optimal:
    - only a small % of the TX and RX buffers are used. This can be changed
in if_bcmreg.h.
    - RX DMAs into fixed buffers and then these are copied to mbufs.
    - the device stats aren't read
    - I don't know what to add into some of the timer and media routines, if
anyone can suggest what's
needed then I would be grateful.
    - LOR on unload.

I will be trying to fix these over the next couple of days.

I will be on holiday 5th July to 13th July, so please forgive any delay in
replying to problems.

Enjoy

Duncan
