lwip: Allow up to 20 byte hardware address to support infiniband.

Infiniband has a positively crazy mapping of ip to it's infiniband
form, and that crazy mapping leads to a 20 byte hardware address
used for ip (despite really only having a 8 byte hardware address).
Infiniband routers such a crazy idea.
