CONFIG_BOOTP_MASK
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.
