man igb contains the section
kern.ipc.nmbclusters
The maximum number of mbuf clusters allowed. If the system has
more than one igb card or jumbo frames are enabled, this value
will need to be increased.
Given that I'm in the process of setting up a new server with two igb
interfaces, is there a suggestion for what I should set it to?
My current value is
root at arthur:4# sysctl kern.ipc.nmbclusters
kern.ipc.nmbclusters: 2020126
