[lwip-users] lwip packet buffers

[Guillaume Fortaine]

Hello,

Here is an interesting comment :

http://forum.chibios.org/phpbb/viewtopic.php?f=3&t=23&start=50#p2647

"lwIP become much better with 1.4, so many less integration problems.
The problem I see in its architecture is that pbufs are allocated from
and freed to lwIP itself, probably it should be the Ethernet driver
handling pbufs internally and have them returned after use. This would
allows to map pbufs to physical buffers in those architectures
allowing that. Basically would allow the driver to optimize the
exchange of data, the TCP/IP stack should only define the interface
for pbuf chains, implementation would be hidden."


What do you think of it ?

I look forward to your answer,

Best Regards,
