* This module contains the implementation of the OS Services buffer pool
* management service. This module provides routines for creating pools
* of buffers for exchange of network data, getting and returning buffers
* from and to the pool, and some other utility functions.
* <P>
* Currently, the pool has 2 underlying implementations - one for the vxWorks
* OS, and another which attempts to be OS-agnostic so that it can be used on
* other OS's such as Linux. The API is largely the same for all OS's,
* but there are some differences to be aware of. These are documented
* in the API descriptions below.
* <P>
* The most significant difference is this: when this module is used with
* the WindRiver VxWorks OS, it will create a pool of vxWorks "MBufs".
* These can be used directly with the vxWorks "netBufLib" OS Library.
* For other OS's, it will create a pool of generic buffers. These may need
* to be converted into other buffer types (sk_buff's in Linux, for example)
* before being used with any built-in OS routines available for
* manipulating network data buffers.
