* So considering the packet counter to be a 32 bit one, we have a

* processed is rounded off to the next power of 2 and put in the
* approriate "bin" the value in the bin gets incremented.
* For example, assume that in CPU 1 if NAPI Rx runs 3 times
* and the packet count processed is as follows (assume the bin counters are 0)
* iteration 1 - 10 (the bin counter 2^4 increments to 1)
* iteration 2 - 30 (the bin counter 2^5 increments to 1)
* iteration 3 - 15 (the bin counter 2^4 increments by 1 to become 2)

/*
* The CPU Candidacy Algorithm
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~
* The available CPUs for selection are divided into two groups
* Primary Set - A CPU mask that carries the First Choice CPUs
* Secondary Set - A CPU mask that carries the Second Choice CPUs.
*
* There are two types of Job, that needs to be assigned to
* the CPUs, from one of the above mentioned CPU group. The Jobs are
* 1) Rx Packet Processing - napi_cpu
* 2) Completion Processiong (Tx, RX) - compl_cpu
*
* To begin with both napi_cpu and compl_cpu are on CPU0. Whenever a CPU goes
* on-line/off-line the CPU candidacy algorithm is triggerd. The candidacy
* algo tries to pickup the first available non boot CPU (CPU0) for napi_cpu.
* If there are more processors free, it assigns one to compl_cpu.
* It also tries to ensure that both napi_cpu and compl_cpu are not on the same
* CPU, as much as possible.
*
* By design, both Tx and Rx completion jobs are run on the same CPU core, as it
* would allow Tx completion skb's to be released into a local free pool from
* which the rx buffer posts could have been serviced. it is important to note
* that a Tx packet may not have a large enough buffer for rx posting.

* If the hotplug worker is already running, no worries because the
* candidacy algo would then reflect the same in dhd->rx_napi_cpu.
