1262 * The CPU Candidacy Algorithm

1264 * The available CPUs for selection are divided into two groups
1265 * Primary Set - A CPU mask that carries the First Choice CPUs
1266 * Secondary Set - A CPU mask that carries the Second Choice CPUs.
1267 *
1268 * There are two types of Job, that needs to be assigned to
1269 * the CPUs, from one of the above mentioned CPU group. The Jobs are
1270 * 1) Rx Packet Processing - napi_cpu
1271 * 2) Completion Processiong (Tx, RX) - compl_cpu
1272 *
1273 * To begin with both napi_cpu and compl_cpu are on CPU0. Whenever a CPU goes
1274 * on-line/off-line the CPU candidacy algorithm is triggerd. The candidacy
1275 * algo tries to pickup the first available non boot CPU (CPU0) for napi_cpu.
1276 * If there are more processors free, it assigns one to compl_cpu.
1277 * It also tries to ensure that both napi_cpu and compl_cpu are not on the same
1278 * CPU, as much as possible.
1279 *
1280 * By design, both Tx and Rx completion jobs are run on the same CPU core, as it
1281 * would allow Tx completion skb's to be released into a local free pool from
1282 * which the rx buffer posts could have been serviced. it is important to note
1283 * that a Tx packet may not have a large enough buffer for rx posting.

3052 * This function call ensures that hotplug mechanism does not kick-in
