Michal Kalderon 0518c12f1f qed*: LL2 callback operations
LL2 today is interrupt driven - when tx/rx completion arrives [or any
other indication], qed needs to operate on the connection and pass
the information to the protocol-driver [or internal qed consumer].
Since we have several flavors of ll2 employeed by the driver,
each handler needs to do an if-else to determine the right functionality
to use based on the connection type.

In order to make things more scalable [given that we're going to add
additional types of ll2 flavors] move the infrastrucutre into using
a callback-based approach - the callbacks would be provided as part
of the connection's initialization parameters.

In order to increase the number of possible Tx connections [queues]

Until now we used to have a single VF legacy compatibility mode,
one that affected the place of the Rx producers of those VFs [mostly].

As PF would soon support allocating CIDs for VFs instead of having
a static CID<->queue configuration for them, we'll need to have
an additional legacy mode since existing VFs would need to continue
on using the older mode of operation.

Change the infrastrucutre so that the legacy would be able to indicate
which of the legacy behaviors is needed for a given VF.

Each PF has a bitmap for its own ranges of CIDs, to allow easy grabbing
of an available CID when such is needed. But VFs are not using the same
mechanism, instead relying on hard-coded CIDs [ queue-index == cid ].

As an infrastructure step toward increasing number of CIDs of VFs,
the PF is going to maintain bitmaps for the VF CIDs as well -
the bitmaps would be per-VF and the ranges would be the same [in HW all
VFs of a given PF have the same mapping of CIDs, and the HW is capable
of distinguishing between those according to the VF index]

Mintz, Yuval ebbdcc669c qed: Reset IGU CAM to default on init
The IGU CAM contains an assocaition between hardware SBs
and interrupt lines, and it can be dynamically configured
to allow more interrupts in one entity over another, specifically
for Re-distibution of SBs between a PF and its child VFs.

While we don't yet use this functionality, there are other
clients that do and as such its possible the information
passed from management firmware during initialization in
regard to the possible number of SBs doesn't accurately reflect
the current HW configuration.

The following changes are going to apply to the driver init sequence:

 a. PF is going to re-configure all entries belonging to itself and
    its child VFs in IGU CAM based on the management firmware info
    regarding the number of SBs that are supposed to exist there.

 b. PF is going to stop using the SB resource [management firmware
    provided information] for anything but the initialization.
    Instead, it would use the live-time counters it maintains for
    the numbers.

Today, driver has a synchronization point while closing
the device which synchronizes its slowpath interrupt line.
However, that's insufficient as that ISR would schedule the
slowpath-tasklet - so even after ISR is over it's possible the
handling of the interrupt has not completed.

By doing a disable/enable on the taskelt we guarantee that all
HW events that should no longer be genereated from that point

However, there are flows where the primary MAC of the device can change
without said NDO being called [bond device in TLB mode configuring

between what's apparent to user [the netdevice's value] and what's
configured in the HW [the private value].

When management firmware declares that the device is WoL-capable,
the default driver behavior would be to allow the management firmware
to take the decision of whether it's actually needed or not.

Problem is ethtool interface doesn't have a 'default' kind
of option, and user would see the interface WoL as disabled,
which doesn't accurately reflect the actual configuration.
More-so, if the user actually wants to explicitly disable WoL he'd have
to first enable it [otherwise ethtool would block the command].

Instead of allowing management to make the decision, enable WoL by
default on all devices capable of it.

Content-wise, the firmware contains fixes to various issues exposed

 - Corrects iSCSI fast retransmit when data digest is enabled.
 - Stop draining packets when receiving several consecutive PFCs.
 - Prevent possible assertion when consecutively opening/closing
   many connections.
 - Prevent possible assertion due to too long BDQ fetch time.

In addition, the new firmware would allow us to later add iWARP support

Mintz, Yuval 07ff2ed03b qed: Prevent warning without CONFIG_RFS_ACCEL
After removing the PTP related initialization from slowpath start,
the remaining PTT entry is required only in case CONFIG_RFS_ACCEL is set.
Otherwise, it leads to a warning due to it being unused.

When calculating doorbell BAR partitioning round up the number of
CPUs to the nearest power of 2 so the size of the DPI (per user

not truncated.

sudarsana.kalluru@cavium.com 035744975a qede: Add support for PTP resource locking.
The patch adds necessary changes to the driver to use qed resource
locking functionality. Currently the ptp initialization is spread
between driver probe/open implementations, associated APIs are
qede_ptp_register_phc()/qede_ptp_start(). Clubbed this functionality
into single API qed_ptp_enable() to simplify the usage of qed resource
locking implementation. The new API will be invoked in the probe path.
Similarly the ptp clean-up code is moved to qede_ptp_disable() which
gets invoked in the driver unload path.

The patch adds support for per-port resource lock in favour of PTP.
PTP module acquires/releases the MFW resource lock while enabling/
disabling the PTP on the interface. The PF instance which has the
ownership of this resource lock will get the exclusive access to the
PTP clock functionality on the port.
