 * List of RPS CPU maps for different rx queues registered by WLAN driver
 * Ref - Kernel/Documentation/networking/scaling.txt
 * RPS CPU map for a particular RX queue, selects CPU(s) for bottom half
 * processing of RX packets. For example, for a system with 4 CPUs,
 * 0xe: Use CPU1 - CPU3 and donot use CPU0.
 * 0x0: RPS is disabled, packets are processed on the interrupting CPU.
.*
 * WLAN driver registers NUM_TX_QUEUES queues for tx and rx each during
 * alloc_netdev_mq. Hence, we need to have a cpu mask for each of the rx queues.
 *
 * For example, if the NUM_TX_QUEUES is 4, a sample WLAN ini entry may look like
 * rpsRxQueueCpuMapList=a b c d
 * For a 4 CPU system (CPU0 - CPU3), this implies:
 * 0xa - (1010) use CPU1, CPU3 for rx queue 0
 * 0xb - (1011) use CPU0, CPU1 and CPU3 for rx queue 1
 * 0xc - (1100) use CPU2, CPU3 for rx queue 2
 * 0xd - (1101) use CPU0, CPU2 and CPU3 for rx queue 3

 * In practice, we may want to avoid the cores which are heavily loaded.
 *
 * Default value of rpsRxQueueCpuMapList. Different platforms may have
 * different configurations for NUM_TX_QUEUES and # of cpus, and will need to
 * configure an appropriate value via ini file. Setting default value to 'e' to
 * avoid use of CPU0 (since its heavily used by other system processes) by rx
 * queue 0, which is currently being used for rx packet processing.
 *
 * Maximum length of string used to hold a list of cpu maps for various rx
 * queues. Considering a 16 core system with 5 rx queues, a RPS CPU map
 * list may look like -
 * rpsRxQueueCpuMapList = ffff ffff ffff ffff ffff
 * (all 5 rx queues can be processed on all 16 cores)
