@subsection Optional Endian Conversion Routines
In a networked environment, each program communicating must agree on the
format of data passed between the various systems in the networked
application. Routines such as @code{ntohl()}
and @code{htonl()} are used to convert
between the common network format and the native format used on this
particular host system. Although RTEMS has a portable implementation of
these endian conversion routines, it is often possible to implement these
routines more efficiently in a processor specific fashion.
The @code{CPU_HAS_OWN_HOST_TO_NETWORK_ROUTINES} is set to TRUE when the port
provides its own implementation of the network to host and host to network
family of routines. This set of routines include the following:
@itemize @bullet
@item @code{ntohl()}
@item @code{ntohs()}
@item @code{htonl()}
@item @code{htons()}
@end itemize
The following example illustrates how this macro should be set when the
generic, portable implementation of this family of routines is to be used
by this port:
@example
#define CPU_HAS_OWN_HOST_TO_NETWORK_ROUTINES FALSE
@end example
@section Extra Stack for MPCI Receive Thread
The @code{CPU_MPCI_RECEIVE_SERVER_EXTRA_STACK} macro is set to the amount of
stack space above the minimum thread stack space required by the MPCI
Receive Server Thread. This macro is needed because in a multiprocessor
