[lwip-users] Cannot connect to Windows 7 ethernet interface directly or through a hub

[William McKinney]

I am running lwip with a micrel ksz8851snl driver on a SiliconLabs gecko (ARM 
CortexM3) processor.  lwip is acting as a TCP server.  If I connect to the 
server from a PC running Windows 7 through an ethernet switch everything works 
fine.  If I connect directly to the PC via a crossover cable or connect through 
an ethernet hub I see lots of dropped packets are retransmissions.  Linux PCs 
work fine regardless of how they are connected to the lwip server.  

I am at having a great deal of trouble figuring out why Windows behaves so 
differently from linux.  If someone out there has any ideas I would appreciate 
the help.

Thank you.
