      qed*: LL2 callback operations · 0518c12f
      由 Michal Kalderon 提交于 
      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.

      qed: Hold a single array for SBs · 50a20714
      由 Mintz, Yuval 提交于 
      A PF today holds 2 different arrays - one holding information
about the HW configuration and one holding information about
the SBs that are used by the protocol drivers.
These arrays aren't really connected - e.g., protocol driver
initializing a given SB would not mark the same SB as occupied
in the HW shadow array.

Move into a single array [at least for PFs] - hold the mapping
of the driver-protocol SBs on the HW entry which they configure.

      qed: Use BDQ resource for storage protocols · d0d40a73
      由 Mintz, Yuval 提交于 
      Until now, qed used some port-defined value as BDQ index for both iSCSI
and FCoE.

As management firmware now treats BDQ as a resource and tells each PF
its BDQ-range, start using a valure from that range instead.

      qed: Utilize resource-lock based scheme · 9c8517c4
      由 Tomer Tayar 提交于 
      Management firmware is used as an arbiter between the various PFs
in matters of resources, but some of the resources that need to
be divided are dependent on the non-management firmware used,
so management firmware first needs to be told how many resources
there are before trying to divide them.

As part of the initialization sequence, driver would first inform
the management firmware of the available resources under
a dedicated resource lock, and afterwards request for various
resources which might be based on the previous set values.

      qed: Move to new load request scheme · 5d24bcf1
      由 Tomer Tayar 提交于 
      Management firmware is used as an arbiter between the various PFs
in regard to loading - it causes the various PFs to load/unload
sequentially and informs each of its appropriate rule in the init.

But the existing flow is too weak to handle some scenarios where
PFs aren't properly cleaned prior to loading.
The significant scenarios falling under this criteria:
  a. Preboot drivers in some environment can't properly unload.
  b. Unexpected driver replacement [kdump, PDA].

Modern management firmware supports a more intricate loading flow,
where the driver has the ability to overcome previous limitations.
This moves qed into using this newer scheme.

Notice new scheme is backward compatible, so new drivers would
still be able to load properly on top of older management firmwares
and vice versa.

      qed: Correct HW stop flow · 1226337a
      由 Tomer Tayar 提交于 
      Management firmware is used as arbiter between different PFs
which are loading/unloading, but in order to use the synchronization
it offers the contending configurations need to be applied either
between their LOAD_REQ <-> LOAD_DONE or UNLOAD_REQ <-> UNLOAD_DONE
management firmware commands.

Existing HW stop flow utilizes 2 different functions: qed_hw_stop() and
qed_hw_reset() which don't abide this requirement; Most of the closure
is doing outside the scope of the unload request.

This patch removes qed_hw_reset() and places the relevant stop
functionality underneath the management firmware protection.
