Align the use of local PTT to propagate through the qed_mcp* API's.
Global ptt should not be used.
Register access should be done through layers. Register address is
mapped into a PTT, PF translation table. Several interface functions
require a PTT to direct read/write into register. There is a pool of
PTT maintained, and several PTT are used simultaneously to access
device registers in different flows. Same PTT should not be used in
flows that can run concurrently.
To avoid running out of PTT resources, too many PTT should not be
acquired without releasing them. Every PF has a global PTT, which is
used throughout the life of PF, in most important flows for register
access. Generic functions acquire the PTT locally and release after
the use. This patch aligns the use of Global PTT and Local PTT
accordingly.

Currently driver registers to physical link notifications (of the device)
from Management firmware (MFW). Driver doesn't get notified if there's a
change in the virtual link e.g., link-flap on the peer PF interface.
Virtual link indication from MFW reflects the per PF link status instead
of the physical link.
The patch adds driver support for,
- Advertising the virtual link support to MFW.
- Handling the virtual link notification from MFW.
Please consider applying it to 'net-next'.

Fix this by using a switch statement to convert between the enumerated
values since they are not 1 to 1, which matches how the rest of the
driver handles this conversion.

The structure shared between driver and the management FW (mfw) differ in
sizes. This would lead to issues when driver try to access the structure
members which are not-aligned with the mfw copy e.g., data_ptr usage in the
case of mfw_tlv request.
Align the driver structure with mfw copy, add reserved field(s) to driver
structure for the members not used by the driver.

In multi-function mode, driver receives the stag value (outer vlan)
for a PF from management FW (MFW). If the stag value is negotiated prior to
the driver load, then the stag is not notified to the driver and hence
driver will have the invalid stag value.
The fix is to request the MFW for STAG value during the driver load time.

Keep sending mailbox commands to the MFW when it is not responsive ends up
with a redundant amount of timeout expiries.
This patch prints the MCP status on the first command which is not
responded, and blocks the following commands.
Since the (un)load request commands might be not responded due to other
PFs, the patch also adds the option to skip the blocking upon a failure.

The MFW manages an internal lock to prevent concurrent hardware

This, together with the busy-waiting for the MFW's responses for commands,
might lead to a deadlock during concurrent load or unload of PFs.
This patch adds the option to sleep within the busy-waiting, and uses it
for the (un)load requests (which are not sent from an interrupt context) to
prevent the possible deadlock.

RoCE qps use a pair of physical queues (pq) received from the Queue Manager
(QM) - an offload queue (OFLD) and a low latency queue (LLT). The QM block
creates a pq for each TC, and allows RoCE qps to ask for a pq with a
specific TC. As a result, qps with different VLAN priorities can be mapped
to different TCs, and employ features such as PFC and ETS.

Apparently, MFW publishes EEE capabilities even for Fiber-boards that don't

to be enabled.

By default, driver sets the eswitch mode incorrectly as VEB (virtual
Ethernet bridging).
Need to set VEB eswitch mode only when sriov is enabled, and it should be
to set NONE by default. The patch incorporates this change.

Memory size is limited in the kdump kernel environment. Allocation of more
msix-vectors (or queues) consumes few tens of MBs of memory, which might
lead to the kdump kernel failure.
This patch adds changes to limit the number of MSI-X vectors in kdump
kernel to minimum required value (i.e., 2 per engine).

Do not advertise DCBX_LLD_MANAGED capability i.e., do not allow
external agent to manage the dcbx/lldp negotiation. MFW acts as lldp agent
for qed* devices, and no other lldp agent is allowed to coexist with mfw.
Also updated a debug print, to not to display the redundant info.
