/**
* @page mem_err Debugging memory pool sizes
* If you have issues with lwIP and you are using memory pools, check that your pools
* are correctly sized.\n
* To debug pool sizes, \#define LWIP_STATS and MEMP_STATS to 1. Check the global variable
* lwip_stats.memp[] using a debugger. If the "err" member of a pool is > 0, the pool
* may be too small for your application and you need to increase its size.
