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

[Simon Goldschmidt]

Follow-up Comment #3, task #6827 (project lwip):

I also think this should be an option as it definitively increases code size,
yes.

>I've implemented a simple one-entry cache to find_entry() (the actual code
was suggested by somebody else).

That's what I have also thought of as a simple implementation...

Swapping the array entries could be a good idea, but a) you copy 2 whole
entries every time sending a packet and b) you could end up switching there
and back again using 2 simultaneous connections!
