esxi/network-firstboot-mtu

Set the ESXi software install acceptance level.

Sets the MTU frame size ("jumbo" frames) for the installed ESXi instance on first boot for the Management Network vSwitch (typically vSwitch0).

Valid values as defined by VMware for this field are from 1000 to 9999.

Typically the system default is 1500 bytes. This value may be set larger in environments using large frames (aka "jumbo"), which typically are a value close to 9000 bytes. In some virtualized environments where additional layers of overhead for encapsulation are needed, the packet may be larger than 9000 bytes.
