retransmitted without suppression, while there is demand for
such ARP entry. As before, retransmission is rate limited to
one packet per second. Details:
- Remove net.link.ether.inet.host_down_time
- Do not set/clear RTF_REJECT flag on route, to
avoid rt_check() returning error. We will generate error
ourselves.
- Return EWOULDBLOCK on first arp_maxtries failed
requests , and return EHOSTDOWN/EHOSTUNREACH
on further requests.
- Retransmit ARP request always, independently from return
code. Ratelimit to 1 pps.
