[Click] Help with Click HashMap

[Swati Sinha Deb]

Hi Eddie,

Sending the copy of packet does work. I was getting error "LinearIPLookup: 
no gw for 90000e0" because I was calling _pkt_map.remove(pktid_) in my 
callback. I thought that "remove" simply removes the entry from HashMap but 
looking at the code seems it destroys the Key and the Value. If I don't 
remove the entry can HashMap handle very very large number of entries? 
Another question, clone won't help me to change the packet. I would like to 
change the packet in my callback and send the packet from there to 
downstream element. Please advice. Thanks.

regards,
Swati
