- * 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)

- * 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

- * 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
