Yes, this is "netdemo" in network-demos.

I thought that was this: "CONFIGURE_MESSAGE_BUFFER_MEMORY".

There's a function to do it manually but I don't see how that's 
different than the call the bsp makes.

Tracing the source code, I see this error message "Can't get network 
memory" is generated right after
a "malloc()" call:

//**************************
  in "rtems_glue.c"


  /*
  * Do the initializations required by the BSD code
  */
static int
bsd_init (void)
{
         int i;
         char *p;
.
.
.

         p = rtems_bsdnet_malloc_mbuf(nmbuf * MSIZE + MSIZE - 
1,MBUF_MALLOC_MBUF);
         p = (char *)(((uintptr_t)p + MSIZE - 1) & ~(MSIZE - 1));
         if (p == NULL) {
                 printf ("Can't get network memory.\n");
                 return -1;
         }
.
.
.
}

//***********************
and in:  "rtems_malloc_mbuf.c"


void* rtems_bsdnet_malloc_mbuf(size_t size, int type)
{
    return malloc(size);
}


So I'm wondering if I've over allocated or something.

One issue on the "CONIGURE" items is what units the memory size is in. 
Someplace I saw that it was
in *kbytes* but elsewhere it appears to be in *bytes*. If it's in 
*kbytes* I could easily have over allocated
elsewhere and not allowed anything for networking.
