From: Todd Fujinaka <todd.fujinaka@intel.com>
A customer was chain-booting to provision his systems and one of the steps was setting MFS. MFS isn't cleared by normal warm reboots (clearing requires a GLOBR) and there was no indication of why Jumbo Frame receives were failing.
Add a warning if MFS is set to anything lower than the default.
