| 19 | help |
| 20 | Some DHCP servers are capable to do a dynamic update of a |
| 21 | DNS server. To do this, they need the hostname of the DHCP |
| 22 | requester. |
| 23 | If CONFIG_BOOTP_SEND_HOSTNAME is defined, the content |
| 24 | of the "hostname" environment variable is passed as |
| 25 | option 12 to the DHCP server. |

| 33 | not be added to the environment. |

| Patrick Delaunay | 421de7f | 2020-04-22 14:18:25 +0200 | [diff] [blame] | 63 | The MTU is typically 1500 for ethernet, so a TFTP block of |
| 64 | 1468 (MTU minus eth.hdrs) provides a good throughput with |
| 65 | almost-MTU block sizes. |
| 66 | You can also activate CONFIG_IP_DEFRAG to set a larger block. |
