Re: [lwip-users] IP reassembly

[Ed Sutter]

Yea, I have to think about that.  I used this uC/OS-LWIP combination on
a project in the past and quickly moved it over to a new project because
of the success I had with it on the first one.  This new project is quite
different, so it may not be applicable.  The hardware it's on could
support linux (i.e. plenty of memory/horsepower), but I don't need to
go that far, maybe RTEMS/BSD...
Thanks
