3  * lwIP internal memory pools (do not use in application code)
4  * This file is deliberately included multiple times: once with empty
5  * definition of LWIP_MEMPOOL() to handle all includes and multiple times
6  * to build up various lists of mem pools.

10  * SETUP: Make sure we define everything we will need.
11  *
12  * We have create three types of pools:
13  *   1) MEMPOOL - standard pools
14  *   2) MALLOC_MEMPOOL - to be used by mem_malloc in mem.c
15  *   3) PBUF_MEMPOOL - a mempool of pbuf's, so include space for the pbuf struct
16  *
17  * If the include'r doesn't require any special treatment of each of the types
18  * above, then will declare #2 & #3 to be just standard mempools.
