01491d291e net/qede/base: introduce HW/SW channel
Introduce 2 new API functions, one for the VF and the other for
PF [per-VF] which allows to decide whether to use HW/SW channel
for PF<->VF communication(a per-VF configuration). A HyperV might
have different VMs with different requirements.

4be18885d1 net/qede/base: avoid possible race condition
There's a possible race in multiple VF scenarios for base driver users
that use the optional APIs ecore_iov_pf_get_and_clear_pending_events,
ecore_iov_pf_add_pending_events. If the client doesn't synchronize the two
calls, it's possible for the PF to clear a VF pending message indication
without ever getting it [as 'get & clear' isn't atomic], leading to VF
timeout on the command.

The solution is to switch into a per-VF indication rather than having a
bitfield for the various VFs with pending events. As part of the solution,
the setting/clearing of the indications is done internally by base driver.
As a result, ecore_iov_pf_add_pending_events is no longer needed and
ecore_iov_pf_get_and_clear_pending_events loses the 'and_clear' from its
name as its now a proper getter.

A VF would be considered 'pending' [I.e., get_pending_events() should
have '1' for it in its bitfield] beginning with the PF's base driver
recognizing a message sent by that VF [in SP_DPC] and ending only when
that VF message is processed.

a90c566f43 net/qede/base: changes for VF queue zone
Allow opening Multiple Tx queues on a single qzone for VFs.
This is supported by Rx/Tx TLVs now having an additional extended TLV that
passes the `qid_usage_idx', a unique number per each queue-cid that was
opened for a given queue-zone.

Fix to overcome TX timeout issue due to more than 16 CIDs by adding an
additional VF legacy mode. This will detach the CIDs from the original
only-existing legacy mode suited for older releases.
Following this change, only VFs that would publish VFPF_ACQUIRE_CAP_QIDS
would have the new CIDs scheme applied. I.e., the new 'legacy' mode is
actually whether this capability is published or not.

Changed the logic to clear doorbells for legacy and non-legacy VFs, so
the PF is cleaning the doorbells for both cases.

eb8e81ad0d net/qede/base: multi-Txq support on same queue-zone for VFs
A step toward having multi-Txq support on same queue-zone for VFs.

This change takes care of:

 - VFs assume a single CID per-queue, where queue X receives CID X.
   Switch to a model similar to that of PF - I.e., Use different CIDs
   for Rx/Tx, and use mapping to acquire/release those. Each VF
   currently will have 32 CIDs available for it [for its possible 16
   Rx & 16 Tx queues].

 - To retain the same interface for PFs/VFs when initializing queues,
   the base driver would have to retain a unique number per-each queue
   that would be communicated in some extended TLV [current TLV
   interface allows the PF to send only the queue-id]. The new TLV isn't
   part of the current change but base driver would now start adding
   such unique keys internally to queue_cids. This would also force
   us to start having alloc/setup/free for L2 [we've refrained from
   doing so until now]
   The limit would be no-more than 64 queues per qzone [This could be
   changed if needed, but hopefully no one needs so many queues]

 - In IOV, Add infrastructure for up to 64 qids per-qzone, although
   at the moment hard-code '0' for Rx and '1' for Tx [Since VF still
   isn't communicating via new TLV which index to associate with a
   given queue in its queue-zone].

a55e422e4e net/qede/base: make L2 queues handle based
L2 handler changes:

This is change to remove the queue-id/qzone difference for Tx queues.

It does that by mainly doing:

a. VFs queues are no longer determined by the SBs they're using.
Instead, the ecore-client needs to maintain those and choose the values
to be used by VF when initializing it.

b. Eliminate the HW-cid array in the hw-function.
To do that, have all the rx/tx functionality turn into 'handle' base -
when queue would be started the caller would get a (void*) handle,
which it would later use with ecore for configuring various
queue-related stop [update, close].
