Comment 8 for bug 1288923

Hi Ed, I believe you are talking about multiple dhcp agents for the same network,
I'm talking about different dhcp agents, for different networks,
 imagine you have networks

A,B,C,D with agents a,b,c,d

then you remove a from a,b,c,d from their serving hosts (H1)

then you add them to serve on a different host (H2), but in different order b,c,a,d ... or a,b,c,d again...

Wouldn't you end with mixed ports for different networks?, or the net/subnet is used here when you lookup
for the port at re-association time?,

re-reading the code in a minute.
