[lwip-devel] etharp_XX_input questions

[Jani Monoses]

Hello

I see that etharp_ip_input() and etharp_arp_input() both return only
NULL and that is stated in their javadoc too. However the ethernet
drivers still check in their input routine whether the returned pbuf is
non NULL and send that pbuf out if that's the case. Is that old code
that can be deleted? Leon?Or is there something in the etharp TODO list
which will make the above mentioned functions return valid pbufs
sometime?

thanks
Jani
