[lwip-devel] Re: lwIP on RTLinux-GPL

[Sergio PérezAlcañiz]

Hello again. If the other -devel subscribers have no objection in including the
porting to RTLinux in the CVS... 
How do I do that????
The porting is based on the 0.6.1 lwIP version.
I've no objection in porting the last one, but... should I update all files to
comply with the last version everytime a new release appears???

Regards.
Sergio.
