ARP stuffing

Anyone know if ARP stuffing is supported in the TI Linux port for Sitara?

I don't think you need to have any sort of special kernel support for
this, other than TCP/IP networking. Just add a static arp entry via
your favorite networking command:

  man arp
  arp -s address hw_address

  ip help neighbor
  ip neighbor add address lladdr hw_address dev eth0

...where "address" is the IP address you're "assigning", and
hw_address is the target MAC address.
