[tulip] MX98715 AEC Problems

[David Ogborn]

Hello,

   I'm having some problems getting an MX98715-AEC based NIC to work with
kernel version 2.2.16 and tulip driver version 0.92k (from the .../test/
directory at the scyld.com website).  Looking back through the archives of
this list, I see that similar problems were encountered by a few back in
October/November of 1999, but the thread seems to have dissappeared.  Any
help people can offer to the problem described below would be greatly
appreciated!

   In brief, when hooked to a 10Mbaud hub, I have no problems with the
card.  When I instead connect it to my Terayon cable modem (connected to
the Internet), which I gather is some sort of 100MBaud device, it has
trouble receiving packets.  

   In more detail:
