bnx2x: Spread rx buffers between allocated queues
Default number of rx buffers will be divided equally
between allocated queues. This will decrease amount of
pre-allocated buffers on systems with multiple CPUs.
User can override this behavior with ethtool -G.
Minimum amount of rx buffers per queue set to 128.
