---help---
Dynamic memory allocations for TCP/IP.
When set to 0 all dynamic allocations are disabled.
When set to 1 a new connection will be allocated every time,
and it will be free'd when no longer needed.
Setting this to 2 or more will allocate the connections in
batches (with batch size equal to this config). When a
connection is no longer needed, it will be returned to the
free connections pool, and it will never be deallocated!

---help---
If dynamic connections allocation is selected (NET_TCP_ALLOC_CONNS > 0)
this will limit the number of connections that can be allocated.
This is useful in case the system is under very heavy load (or
under attack), ensuring that the heap will not be exhausted.
