Network won't initialize

[Steve Hunt]

I had a problem (perhaps the same) with a realtek chip, I reported it to
the mailing list some time ago.  It was a problem with IP checksum not
being calculated correctly (have a look with etherreal)- strangely a
delay in the code calling the checksum routine made it work! - but then
(in cpukit/libnetworking/netinet/ip_output.c) I changed the calls to ip-
>ip_sum = in_cksum_hdr(ip); into ip->ip_sum = in_cksum(m, hlen); and it
works.

More recently there was a long discussion on checksums ... indicating
problems due to compiler optimizations, so maybe it has now been
fixed.
