.SH "DESCRIPTION"
.PP
This initalises the on-card and driver datastructures to
the point where \fBmc32_start_transceiver\fR can be called.
.PP
The card sets up the receive ring for us. We are required to use the
ring it provides, although the size of the ring is configurable.
.PP
We allocate an sk_buff for each ring entry in turn and
initalise its house-keeping info. At the same time, we read
each 'next' pointer in our rx_ring array. This reduces slow
shared-memory reads and makes it easy to access predecessor
descriptors.
.PP
We then set the end-of-list bit for the last entry so that the
card will know when it has run out of buffers.
