Prevent integer overflow in kernel and userland when checking mbuf
limits. Convert kernel variables and calculations for mbuf memory
into long to allow larger values on 64 bit machines. Put a range
check into the kernel sysctl. For the interface itself int is still
sufficient. In netstat -m cast all multiplications to unsigned
long to hold the product of two unsigned int.
