Bug description:
SRU Justification
[Impact]
* Microsoft requested MANA patches for the following:
* Adding device statistics support
* Support for reporting additional hardware counters for drop and TC
using the ethtool -S interface
* Action on receiving the special EQE notification
* Allow separate mana_ib for each mana client
[Fix]
* 5 clean cherry-picks from upstream:
* 9c32c12: "RDMA/mana_ib: Fix error code in probe()"
* 01857af: "RDMA/mana_ib: Add support of mana_ib for RNIC and ETH nic"
* 6e5c9aa: "RDMA/mana_ib: unify mana_ib functions to support any gdma device"
* 2d4af40: "net: mana: use ethtool string helpers"
* 3 backports from upstream:
* efe5a82: "net: mana: Probe rdma device in mana driver"
* 35f3c35: "RDMA/mana_ib: Add support of 4M, 1G, and 2G pages"
* de9368f: "net: mana: Add support for auxiliary device servicing events"
* 1 backport from linux-next:
* 0969d0e: "net: mana: Expose additional hardware counters for drop and TC
via ethtool."
* 1 backport from net-next:
* 1b31168: "net: mana: Add handler for hardware servicing events"
* 1 clean ch erry-pick from rdma-next:
* e114daa: "RDMA/mana_ib: Add device statistics support"
[Test Plan]
* Compile tested
* Microsoft to test further
[Regression potential]
* Changes are largely localized to MANA, and either already upstream
or queued for upstream in the next merge window or maintainer trees.
Possible regressions could result in unexpected behavior of MANA
driver.
