Re: Self Communication for Self Test
It is possible but there are conditions, for example if you have two
interfaces each configured with an IP address that happen to be on the
same subnet, while you will be able to receive communication on both
interfaces transmission will work from only one interface since as you
can't have duplicate entries in the routing table. In such a case, you
would need an instance of io-pkt per interface so you have two routing
tables.
You could get away with creating an alias, so giving an interface a
second IP address and this can be on the same subnet. When you transmit
the packets aren't going to get sent over the wire (so layer 2) they get
forwarded from one queue to the next within the stack. Depending on your
requirements though this might not be sufficient for a self test.
Wouldn't pinging another host on the network be a sufficient test to
demonstrate connectivity?
