+ Some DHCP servers are capable to do a dynamic update of a

Selecting this will allow the Ethernet interface to function
even when the ethaddr variable for that interface is unset.
Support the 'nc' input/output device for networked console.
See README.NetConsole for details.

- If set, allows controlling the TFTP timeout through the

- timeout count through the variable tftptimeoutcountmax.
- If unset, timeout and maximum are hard-defined as 1 second
