[ns] How to reduce IFQ packet drop

[Shanshan Song]

Hi,

I am running wireless network simulation with DSR as
routing protocol. I find there are large amount of
packet drop due to IFQ full. I increased the
IFQ_MAXLEN in dsr-prequeue.h but nothing is improved.
Could anybody tell me how to reduce the IFQ packet
drop thereby improve the throughput?

Thanks.
Shanshan
