Is recommendable set MPSAFENET to 1 in versions 6.x to improve the 
and POLLING in the following system with 8 interfaces IF_EM ??

CPU: Intel(R) Xeon(TM) CPU 3.20GHz (3200.13-MHz 686-class CPU)
 Logical CPUs per core: 2
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
SMP: AP CPU #1 Launched!

   vendor     = 'Intel Corporation'
