[Click] Queue Memory Allocation: vmalloc or kmalloc

[Latency Buster]

I have a machine with 32GB Ram... I am testing a scenario to find out
how long a burst can click handle based on varying service rate. If I
make the incoming queue length = 1.5 million packets, will click
allocate the memory using kmalloc or vmalloc? Since I have a machine
with large ram (32GB), I was thinking of allocating 2GB for packet
queues. Is that feasible with the current version of Click?

Thanks,
