Bjoern A. Zeeb a4c69b8bc0 Make arp code return (more) errors. ... arprequest() is a void function and in case of error we simply return without any feedback. In case of any local operation or *if_output() failing no feedback is send up the stack for the packet which triggered the arp request to be sent. arpresolve_full() has three pre-canned possible errors returned (if we have not yet sent enough arp requests or if we tried often enough without success) otherwise "no error" is returned. Make arprequest() an "internal" function arprequest_internal() which does return a possible error to the caller. Preserve arprequest() as a void wrapper function for external consumers. In arpresolve_full() add an extra error checking. Use the arprequest_internal() function and only return an error if non of the three ones (mentioend above) are already set. This will return possible errors all the way up the stack and allows functions and programs to react on the send errors rather than leaving them in the dark. Also they might get more detailed feedback of why packets cannot be sent and they will receive it quicker.
