[ECOS] FreeBSD-Stack not responding

Hello,
I recently switched from the Open- to the FreeBSD stack (latest CVS
version)
When i try to send Data to my target (e.g. ascii strings via a telnet
client on Linux and/or Windows), the data is lost in the stack (the
"read" call in my application never returns) - even when a connection
could be established and my application could send a "Prompt" to the
telnet client! With the OpenBSD Stack this works fine.
I figured out that packets are dropped in the cyg_tcp_input function
because of a bad checksum.
I got some warnings during the eCos-built:
implicit declarations of function 'cyg_in_cksum_hdr' in ip_input.c:332
implicit declarations of function 'cyg_in_cksum_hdr' and
'cyg_in_cksum_skip'
in ip_output and
implicit declarations of function 'cyg_in_pseudo' in tcp_input:405
(among some others)
Has anybode experienced similar problems with the FreeBSD stack?
Any ideas?
Thanks in advance
Wolfgang
PS: I built the eCos library with the new_net template and removed libm
and dns support.
