| * Now its difficult to capture the "exact" number of packets processed. |
| * 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 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. |
