[lwip-devel] [task #6827] etharp could need some tuning

[Frédéric Bernon]

Follow-up Comment #30, task #6827 (project lwip):

Put "in head" the last entry used is not a real sort (2 pointers to change),
and should be faster than pass an address inside all the stack. If you want
an ARP cache with 20 entries, an send to 5 dest,  with a such feature, you
never compare more than the 5 first entries. But I will read all others
comments to have a better point of view...
