This is needed if the client uses 61 option and the DHCP server applies strict rules
on assigning addresses.
Set this to 'n' if you don't need DHCP or you're using simplified DHCP workflow
without HW address options in DHCP messages.

bool "Enable promiscuous mode on Ethernet interface"
default n
help
Enable promiscuous mode on the Ethernet interface.
Note: Enabling promiscuous mode results in better throughput as MAC addresses
in frames are not rewritten with the Ethernet interface's actual MAC address.
Note: Enabling promiscuous mode may cause ARP conflicts if the PC
is also connected to the same network with another NIC.
