Subject: net: mana: Export Work Queue functions for use by RDMA driver
Patch-mainline: v6.2-rc1
Git-commit: 4c0ff7a106e16ab63e0b597557255c012f179578
References: bsc#1210741 jsc#PED-4022

RDMA device may need to create Ethernet device queues for use by Queue
Pair type RAW. This allows a user-mode context accesses Ethernet hardware
queues. Export the supporting functions for use by the RDMA driver.
