This patch dissociates single-queue indirection tables and hash QP objects from Rx queue structures to relinquish their control to users through the RSS flow rule action, while simultaneously allowing multiple queues to be associated with RSS contexts. Flow rules share identical RSS contexts (hashed fields, hash key, target queues) to save on memory and other resources. The trade-off is some added complexity due to reference counters management on RSS contexts. The QUEUE action is re-implemented on top of an automatically-generated single-queue RSS context. The following hardware limitations apply to RSS contexts: - The number of queues in a group must be a power of two. - Queue indices must be consecutive, for instance the [0 1 2 3] set is allowed, however [3 2 1 0], [0 2 1 3] and [0 0 1 1 2 3 3 3] are not. - The first queue of a group must be aligned to a multiple of the context size, e.g. if queues [0 1 2 3 4] are defined globally, allowed group combinations are [0 1] and [2 3]; groups [1 2] and [3 4] are not supported. - RSS hash key, while configurable per context, must be exactly 40 bytes long. - The only supported hash algorithm is Toeplitz.
