[aprssig] UIFLOOD dual-dupes?

[Bob Bruninga]

Has anyone seen double packets from digipeaters?

I'm testing two digipeaters set to support UIFLOOS of HOPn-N.

When the digipeater originates its own packet as 7-7, the other digi does
digipeat as HOP6-7, but then the sending digi sees that copy and digipeats
it again as HOP5-7.

It appears that these digipeaters are not recognizing their OWN originated
packets as a "dupe" when they see them again, digipeted by another UIFLOOD
digi.  They should ignore their own packets always.

Both of these digis are kenwoods, a D700 and a D72.  Also the D72 throws out
a totally useless CALLSIGN/R ID packet too.
