.SH "DESCRIPTION"
.PP
The user is trying to bring the card into ready state. This requires
a brief dialogue with the card. Firstly we enable interrupts and then
'indications'. Without these enabled the card doesn't bother telling
us what it has done. This had me puzzled for a week.
.PP
We configure the number of card descriptors, then load the network
address and multicast filters. Turn on the workaround mode. This
works around a bug in the 82586 - it asks the firmware to do
so. It has a performance (latency) hit but is needed on busy
[read most] lans. We load the ring with buffers then we kick it
all off.
