Hello all,
I'd like to point out that (at least) the network driver sundance.c has weird
flaws when trying to use more than MAX_UNITS (8) cards at the same time. Since
this driver can be used for DFE-580TX 4 port network card it is really easy to
get more than 8 ports :-)
In fact the driver does check against MAX_UNITS, but does _not_ fail if you go
through the roof. Instead you can expect really interesting ifconfig-outputs
;-)
IMHO it should check and fail. I wonder what other card drivers do in such a
case ...

Stephan

... and to have even more fun:
"ifconfig" coming with SuSE 8.1 produces broken output list if there is ethX
with X>9.
(just in case someone is listening ... ;-)

Please define "weird flaws"... explicitly.

Other card drivers handle this case just fine. The expected behavior is
that module options will only support up to MAX_UNITS of certain
arguments, but beyond that nothing is affected at all.

I am experiencing dropped packets as sundance RX side when simple nfs copying
takes places. These are at a rate of about 1-2% of RX packets. I call it
"weird" because I cannot see a definitive problem location in the driver
source. fact stays one simple copy drops packets, something I never saw in the
same setup (same cabling, same mainboard) with tulip cards.
I know that this is a hell of a "bug-report", but I really want to point out
only a strange difference between tulip-setup and sundance-setup.
