| 13 | help |
| 14 | Some DHCP servers are capable to do a dynamic update of a |
| 15 | DNS server. To do this, they need the hostname of the DHCP |
| 16 | requester. |
| 17 | If CONFIG_BOOTP_SEND_HOSTNAME is defined, the content |
| 18 | of the "hostname" environment variable is passed as |
| 19 | option 12 to the DHCP server. |

| 24 | Selecting this will allow the Ethernet interface to function |
| 25 | even when the ethaddr variable for that interface is unset. |
| 26 | A new MAC address will be generated on every boot and it will |
| 27 | not be added to the environment. |

| 58 | 1468 (MTU minus eth.hdrs) provides a good throughput with |
| 59 | almost-MTU block sizes. |
| 60 | You can also activate CONFIG_IP_DEFRAG to set a larger block. |
