Maybe i don't understand what you are saying, but if there is no ARP
entry, the IP packet which needs to be sent is normally queued and an
ARP request is sent out. Once an ARP reply is received the queues
packet is then sent. Is this not happening?
ARP will only que one mbuf, then drops it if more come in If a
coldstart and 2 link-up traps occur at powerup, and if we have 2
trapsinks, for example, that's 6 msgs of which 4-5 are dropped. I need
to update the ipdropped snmp stats counter too, cause it took awhile to
figure out where the missing packets were going. Looked tricky to use
arpresolve? without dropping any mbuf queued there also.
