RDMA/ocrdma: Query and initalize the PFC SL
This patch implements routine to query the PFC priority from the
adapter port.
Following are the changes implemented:
* A new FW command is implemented to query the operational/admin DCBX
configuration from the FW and obtain active priority(service
level).
* Adds support for the async event reported by FW when the PFC
priority changes. Service level is re-initialized during modify_qp
or create_ah, based on this event.
* Maintain SL value in ocrdma_dev structure and refer that as and
when needed.

Changes to inet4 and inet6 addresses for the host are monitored and if
the address is associated with an ocrdma device then a gid is added or
deleted from the device's gid table. The gid format will be a IPv4 to
IPv6 mapped or the IPv6 address.

RDMA/ocrdma: Dont use PD 0 for userpace CQ DB
Create_CQ verb doesn't provide a PD pointer. So, until now we are
creating all (both userspace and kernel) CQ DB regions from PD0. This
will result in mmapping PD0 to applications. A rogue userspace
application can mess things up.
Also more serious issues is even the be2net NIC uses PD0.
This patch addresses this problem by:
1) Create a PD page for every userspace application when the
alloc_ucontext is called. This will be destroyed in
dealloc_ucontext.
2) All CQs for that context will use the PD allocated in ucontext.
3) The first create_PD call from application will result in returning
the PD address from its ucontext (no new PD will be created).
4) For subsecquent create_pd calls from application, we create new PDs for
the application.

Fix this by wrapping the inet6 calls in #ifdef IPV6. Also make the

RDMA/ocrdma: Don't sleep in atomic notifier handler
Events sent to ocrdma_inet6addr_event() are sent from an atomic context,
therefore we can't try to lock a mutex within the notifier callback.
We could just switch the mutex to a spinlock since all it does it
protect a list, but I've gone ahead and switched the list to use RCU
instead. I couldn't fully test it since I don't have IB hardware, so
if it doesn't fully work for some reason let me know and I'll switch
it back to using a spinlock.
