Subject: [PATCH net-next 0/2] net: airoha: Allow mapping out-of-order DMA
 tx descriptors

Add the capability to consume out-of-order DMA tx descriptors. This
feature is useful when multiple flows are queued on the same hw tx queue
since it allows to fully utilize the available tx DMA descriptors and to
avoid the starvation of high-priority flow we have in the current
codebase due to head-of-line blocking introduced by low-priority flows.
Reorganize airoha_queue struct.
