d121a6b5f7 net/qede: fix VF MTU update
This patch fixes VF MTU update to work without having to restart the
vport and there by not requiring port re-configuration. It adds a
VF MTU Update TLV to achieve the same. Firmware can handle VF MTU update
by just pausing the vport.

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.

c73d7da71c net/qede/base: support mapped doorbell BARs for VF
Determines whether VF utilizes doorbells via limited register bar or via
the doorbell bar and return the size of the HW doorbell bar via acquire
response. By doing that limit the VF CIDs to an amount that would make sure
doorbells for all CIDs fall within the bar.

30ecf67308 net/qede/base: remove unused parameters
This is an attempt to clean up many unused API parameters across the base
code. Most of the changes are related to removing unused p_hwfn or p_ptt
handlers. The warnings are generated using 'unused-parameter' cflags.

6e4fcea92f net/qede/base: interchangeably use SB between PF and VF
Status Block reallocation - allow a PF and its child VF to change SB
between them using new base driver APIs.

The changes that are inside base driver flows are:

New APIs ecore_int_igu_reset_cam() and ecore_int_igu_reset_cam_default()
added to reset IGU CAM.
 a. During hw_prepare(), driver would re-initialize the IGU CAM.
 b. During hw_stop(), driver would initialize the IGU CAM to default.

Use igu_sb_id instead of sb_idx [protocol index] to allow setting of
the timer-resolution in CAU[coalescing algorithm unit] for all SBs,
sb_idx could limit SBs 0-11 only to be able change their timer-resolution.

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.

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].
