You can fine tune the DHCP functionality by adding

these flags to the CONFIG_BOOTP_MASK define:
|

|

CONFIG_BOOTP_DNS2 - If a DHCP client requests the DNS
|
||||
serverip from a DHCP server, it is possible that more
|
||||
than one DNS serverip is offered to the client.
|
||||
If CONFIG_BOOTP_DNS2 is enabled, the secondary DNS
|
||||
serverip will be stored in the additional environment
|
||||
variable "dnsip2". The first DNS serverip is always
|
||||
stored in the variable "dnsip", when CONFIG_BOOTP_DNS
|
||||
is added to the CONFIG_BOOTP_MASK.
|
||||
|
||||
CONFIG_BOOTP_SEND_HOSTNAME - Some DHCP servers are capable
|
||||
to do a dynamic update of a DNS server. To do this, they
|
||||
need the hostname of the DHCP requester.
|
||||
If CONFIG_BOOP_SEND_HOSTNAME is added to the
|
||||
CONFIG_BOOTP_MASK, the content of the "hostname"
|
||||
environment variable is passed as option 12 to
|
||||
the DHCP server.
