Re: [lwip-users] ppp-new IP forwarding only works one direction (Ethernet to PPP)

[LMao]

Sylvain,

I applied the new patch, but the following statement always cause Data Abort 
exception run-time error. No matter I set ETH_PAD_SIZE to 0 or 2. The good 
thing is my compiler doesn't generate any error message for the new patch.
*((ppp_pcb**)payload) = pcb;

Another thing I am not so sure is the macro PPP_USE_PBUF_RAM. I always set it 
to 1 in lwipopts.h, but I think the default is set to 0 in opt.h. Am I doing 
the right thing?

Thanks,

Charles

Yeah, happy to hear that.

Here is another patch, which should fix the issue in a way that can be pushed 
to the repository, would you test it ?

Humm, this is strange, using ETH_PAD_SIZE should work.
