Description (partial)

Syslog message seen:

%KERN-6-SYSTEM_MSG: [2067550.480638] linux-bcm-knet (0): No Rx API buffers - kernel

These FXOS syslog messages are due to packets destined to the Supervisor CPU that do not hit any of the pre-determined filters which causes them to hit the default one. This filter directs the packet to a destination that is not used and hence dropped. 

This is expected behavior and is should not be a cause for concern.
