#define DHCP_HTYPE_ETH 1

DHCP hardware type, currently only ethernet is supported

Definition at line 151 of file prot/dhcp.h.

#define DHCP_OPTIONS_LEN DHCP_MIN_OPTIONS_LEN

make sure user does not configure this too small allow this to be configured in lwipopts.h, but not too small set this to be sufficient for your options in outgoing DHCP msgs
