I guess you won't get too many really neutral answers on this
list, but I'll reply anyway... Only my opinions of course!
Altera first used lwIP since they needed an inexpensive (or free)
TCPIP stack for their users (many TCPIP stacks are quite
expensive...). They don't seem to have worked too much on this as
they did not even fix the multithreading bug in ARP present in
lwIP 1.2.0 (which they used for NIOS II 5.x, I think - the last
version they suggested lwIP).
Of course they realized it's cheaper for them to get a partner
shipping a TCPIP stack is cheaper than having their own developers
working on lwIP - and the Interniche license isn't too expensive
for their users (I think 250 EUR per developer license).
The pros for Interniche are the better integration into the NIOS
suite and the support for IPv6 (although this seems to cost extra)
as well as some extra modules (that although cost extra) and the
possiblity of getting a support contract from Interniche.
The pros for lwIP are it is free (and free to be modified) and
there might be more additional software available for free (e.g.
SNMP server included, many in the contrib module).
Of course I have to admit lwIP isn't bug-free, but I'll bet my a**
that the Interniche stack isn't, either...

PS: We decided for lwIP, which is what me got here :-) But then
again, we don't use the OS environment provided by Altera...

Interestingly - because Interniche has come up on this list
before - my new project utilizes the NIOS II which recommends
the Interniche TCP/IP stack while essentially denouncing lwIP.
Does anyone have Interniche experience and lwIP experience to
be able share any pros and cons or comparisons between
Interniche and lwIP? I'm leaning towards lwIP because of the
lesser learning curve. I don't have much else to go on at this
point so any feedback would be greatly appreciated.
Thank you,
Bill
