int "Maximum number of TCP/IP connections"
default 0
depends on NET_TCP_ALLOC_CONNS > 0
---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.
