| 18 | bool "Send hostname to DNS server" | |
| 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. | |

| 29 | help | |
| 30 | Selecting this will allow the Ethernet interface to function | |
| 31 | even when the ethaddr variable for that interface is unset. | |
| 32 | A new MAC address will be generated on every boot and it will | |
| 33 | not be added to the environment. | |

| 62 | Default TFTP block size. | |
| 421de7fe PD |
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. | |

| 71 | help | |
| 72 | Default TFTP window size. | |
| 73 | RFC7440 defines an optional window size of transmits, | |
| 74 | before an ack response is required. | |
| 75 | The default TFTP implementation implies a window size of 1. | |
