cdd30ebb1b module: Convert symbol namespace to string literal
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

1df03a4b44 RDMA/mana_ib: Set correct device into ib
Add mana_get_primary_netdev_rcu helper to get a primary
netdevice for a given port. When mana is used with
netvsc, the VF netdev is controlled by an upper netvsc
device. In a baremetal case, the VF netdev is the
primary device.

Use the mana_get_primary_netdev_rcu() helper in the mana_ib
to get the correct device for querying network states.

2a1251e3db RDMA/mana_ib: Process QP error events in mana_ib
Process QP fatal events from the error event queue.
For that, find the QP, using QPN from the event, and then call its
event_handler. To find the QPs, store created RC QPs in an xarray.
