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

[Simon Goldschmidt]

Follow-up Comment #50, task #6827 (project lwip):

> I wonder how much the extra calls to ip_route will affect your
performance.

I'd guess they won't! The old way was to call ip_output which then calls
ip_route and ip_output_if. If ip_route is called from tcp_output directly,
that doesn't change. You can say I'm moving the ip_output functionality into
tcp_output. The only effect is the code gets a little bigger (but really only
a little!). Regarding performance, one function call is saved, so it could
indeed be faster...
