Re: [lwip-users] LLDP Implementation for 1.4.1

[Amit Ashara]

Hello Simon,

Thanks for the list of to-do items. How do I open a patch tracker?

1. As for the heap allocation, it is being released after the packet is
transmitted.
2. Should I remove the opt.h and stats.h defines being integrated in the
lldp.c file?
3. The protocol values are required for LLDP and I checked the other file
for protocol definition and it was kept in ethernetif.h and hence I
followed the same structure. Where do you suggest I move the same?

[lwip-users] How to Free PBUF_POOL or initialize lwIP

[Seongung Yun]

i'm currently developing a tcp based client/server function.

Everytime I make a connection and disconnection to a server, PBUF_POOL uses
more memory and the 

monitoring counter increases as well.

Once, it reaches to the number of "avail", I can not make a connection any
more, because of there's any more pbuf_pool to allow.

I'd like to empty and free the pbuf_pool memory so it can connect/disconnect
no matter how many times i try do.

I tried 

pbuf_free
mem_free
memp_free

tcp_close and initlwip again (but it doesn't proceed from tcp_bind (ERR_USE 
  
-8/* Address in use.)

Was there anything I missed?

Thank you.
