[Click] cpucycles in allocationg buffers and pushing

[Shilpi Agarwal]

Hi!!

The PollDevice statistics give 4 cycles...
cycles poll, cycles refill , cycles allocskb, cycles pushing..but the paper
"Programming language techniques ..." considers only polling and refilling ? why ?

Also in polling device interaction even if we do not receive packets it will
keep polling so how do we measure exact number of cpucyles per packet in polling ?


Thanks
Shilpi
