Hi all,
I try to figure out something simple like the ARP retransmission timeout
to populate the ipv4InterfaceRetransmitTime in the RFC4293 MIB. In line
357 of netinet/if_ether.c it says:
/*
* Return EWOULDBLOCK if we have tried less than arp_maxtries. It
* will be masked by ether_output(). Return EHOSTDOWN/EHOSTUNREACH
* if we have already sent arp_maxtries ARP requests. Retransmit
the
* ARP request, but not faster than one request per second.
*/
Unfortunately the comment about the 1s minimum retransmit interval is
there, but the code not. A simple ping -f shows the code transmitting ARP
requests every 30 milliseconds, which is not good in my opinion. releng-7
(with the old L2 code) works correctly.
BTW, what means the comment on line 282 in the same file?
/* XXXXX
