the networking guide is for the legacy network stack. The libbsd has 
some documentation here:

https://git.rtems.org/rtems-libbsd/tree/libbsd.txt

The network buffers are managed by UMA which uses a page allocator. The 
memory area managed by the page allocator is determined during library 
initialization. You can use the "vmstat -z" and "netstat -m" shell 
commands to figure out something about the memory usage of libbsd.
