    _______________________________________________________

Details:

The following patch allows the LWIP data structures (contents of memp_memory)
to be stored in external memory by #defining LWIP_EXT_RAM_PREFIX and/or
LWIP_EXT_RAM_SUFFIX.

For example, when using the IAR compiler, the following would result in the
memory being allocated in external memory:

#define LWIP_EXT_RAM_SUFFIX '@ "<section name>"'

where <section name> is the name on the section for external memory created
in the linker script. The same can be done for gcc:

#define LWIP_EXT_RAM_SUFFIX __attribute__ ((section ("<section name>")))
