- 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 defined.
