5e7260712b qed: Remove IP services API.
qed_nvmetcp_ip_services.c and its corresponding header file were
introduced in commit 806ee7f81a ("qed: Add IP services APIs support")
but there's still no users for any of the functions they declare.
Since these files are effectively unused, let's just drop them.

Found by code inspection. Compile-tested only.

823163ba6e qed*: esl priv flag support through ethtool
ESL(Enhanced System Lockdown) was designed to lock PCI adapter firmware
images and prevent changes to critical non-volatile configuration data
so that uncontrolled, malicious or unintentional modification to the
adapters are avoided, ensuring it's operational state. Once this feature is
enabled, the device is locked, rejecting any modification to non-volatile
images. Once unlocked, the protection is off such that firmware and
non-volatile configurations may be altered.

Driver just reflects the capability and status of this through
the ethtool private flag.

0cc3a80179 qed*: enhance tx timeout debug info
This patch add some new qed APIs to query status block
info and report various data to MFW on tx timeout event

Along with that it enhances qede to dump more debug logs
(not just specific to the queue which was reported by stack)
on tx timeout which includes various other basic metadata about
all tx queues and other info (like status block etc.)

766607570b ethernet: constify references to netdev->dev_addr in drivers
This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.

Commit 406f42fa0d ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.

No functional changes.

Update TCP silly-window-syndrome timeout, for the cases where
initiator's small TCP window size prevents FW from transmitting
packets on the connection. Timeout causes FW to retransmit
window probes if needed, preventing I/O stall if initiator ignores
first window probe.

fb09a1ed5c qed: Remove e4_ and _e4 from FW HSI
The existing qed/qede/qedr/qedi/qedf code uses chip-specific naming in
structures,  functions, variables and defines in FW HSI (Hardware
Software Interface).

The new FW version introduced a generic naming convention in HSI
in-which the same code will be used across different versions
for simpler maintainability. It also eases in providing support for
new features.

With this patch every "_e4" or "e4_" prefix or suffix is not needed
anymore and it will be removed.

16e7483e6f Merge branch 'dynamic_sg' into rdma.git for-next
From Maor Gottlieb says:

====================
This series extends __sg_alloc_table_from_pages to allow chaining of new
pages to an already initialized SG table.

This allows for drivers to utilize the optimization of merging contiguous
pages without a need to pre allocate all the pages and hold them in a very
large temporary buffer prior to the call to SG table initialization.

The last patch changes the Infiniband core to use the new API. It removes
duplicate functionality from the code and benefits from the optimization
of allocating dynamic SG table from pages.

In huge pages system of 2MB page size, without this change, the SG table
would contain x512 SG entries.
