Yes in my port it's enabled. Should I disable it?

Actually yes it is. However, I tried disabling it in my port while I'm
in the process of transmitting. I have not seen any enhancement. I'm
thinking if I should remove this or not...
I've read one of your posts about this issue on the list. ( December
2006, I guess). When do you think this will cause problems to me? For
example, if I disable etharp_ip_input before calling tcp_output and
re-enable it after tcp_sent, is it an enough protection? I really don't
care answering arp requests for a short period of time as long as it is
not a very very wrong move.
