[ECOS] Ethernet reception error

[Leandro Fanzone]

Hello, I'm using eCos under x86, and using an ethernet onboard card. If 
I setup a simple TCP connection (eCos = server, Windows = client), and I 
send something from the client to the server, with asserts on I have the 
following:

     CYG_ASSERT( rxd + DS_BUFP + MAX_RX_PACKET_SIZE >= from_p,
                "from_p overflow in rx" );

within if_r6040.c, in r6040_recv(...). That only happens when I send() 
packets roughly larger than MAX_RX_PACKET_SIZE (1536 bytes); below that 
value there's no problem. On the other hand, if I turn off asserts, that 
seems to produce no side effects whatsoever, but I'm never really sure. 
Any insights? Thank you in advance.
