Issue

When looking at network port show output, we can see flowcontrol-admin is set to none on all cluster ports, but some have flowcontrol-oper set to full:

cluster::*> net port show -ipspace Cluster -field flowcontrol-admin,flowcontrol-oper (network port show)              

node       port flowcontrol-admin flowcontrol-oper

This can cause some packet discards on the cluster network:
