FP context statistics

---------------------

FP average context/sec 1min

FP context utilization 1min

The show pxf cpu context command displays more useful information on the processor's performance

than the show processor cpu command that is used on other platforms.

This display shows statistics that are based on three counters on the PXF processors:

feed_back—Incremented each time the processor requires another processor cycle to process a

packet. Each PXF processor contains 8 columns that perform different packet header processing

tasks, such as ACL processing or QoS processing. A typical IP packet passes through all 8 columns
