Re: [lwip-users] LWIP -> Microblaze

Hi Lachlan,
Xilinx provides different ethernet MAC hardware configurations and
hence you will find different xemacif_*.c file under
contrib/ports/v2pro area.  As of fixing the file, I will take a
stab at this one and get back to you. 

I have always see that RAW API performs much better than the Sockets
API mode. However, writing a program using the RAW API takes quite a
bit of time. It is always performance vs ease-of-use in programming
which is what the RAW vs Sockets mode offers. Depending on the
requirement you could choose to use one vs the other.

Ah, I was wondering where to look.
The line number you mentioned was beyond EOF.

Well, the raw-API is a little more difficult to use since
it has an event driven nature. You need to create your
own thread and timers for handling these events.
You can read more about this in lwip/doc/rawapi.txt
This code is currently maintained by about 3 to 4
project members.

The socket + sequential API is easier to use but is pretty
much unmaintained nowadays. I was lost trying
to fix some TCP problems and some other users
only came up with useless quick-and-dirty hacks.

Note the example http server uses the sequential API.

It is really up to you. We (Axon) use the raw-API
(the files in lwip/src/core/) and forget about
the files in lwip/src/api.
