qed: FW 8.42.2.0 Additional ll2 type
LL2 queues were a limited resource due to FW constraints. This FW introduced a new resource which is a context based ll2 queue (memory on host). The additional ll2 queues are required for RDMA SRIOV. The code refers to the previous ll2 queues as ram-based or legacy, and the new queues as ctx-based. This change decreased the "legacy" ram-based queues therefore the first ll2 queue used for iWARP was converted to the ctx-based ll2 queue. This feature also exposed a bug in the DIRECT_REG_WR64 macro implementation which didn't have an effect in other use cases.
