Added some IPv6 protocol fields to the default MKEX profile.
They include everything from the beginning of IP header and up to
source address. The pattern occupies full KW2 in MCAM entry.
Only one out of two LD registers for this protocol is used.

KPU profile interpret Extended DSA and eDSA by looking source dev. This
was incorrect and it restricts to use few source device ids and also
created confusion while parsing regular DSA tag. With below patch lookup
was based on bit 12 of Word0. This is always zero for DSA tag and it
should be one for Extended DSA and eDSA.

Marvell Prestera switches supports distributed switch architecture
by inserting Forward DSA tag of 4 bytes right after ethernet SMAC.
This tag don't have a tpid field.
This patch provides parser and extraction support for the same.
Default ldata extraction profile added for FDSA such that Src_port
is extracted and placed inplace of vlanid field. Like extended DSA
and eDSA tags,a special PKIND of 62 is used for this tag.

Refactor KPU related NPC code gathering all configuration data in a
structured format and putting it in one place (npc_profile.h).
This increases readability and makes it easier to extend the profile
configuration (as opposed to jumping between multiple header and source
files).
To do this:
* Gather all KPU profile related data into a single adapter struct.
* Convert the built-in MKEX definition to a structured one to streamline
the MKEX loading.
* Convert LT default register configuration into a structure, keeping
default protocol settings in same file where identifiers for those
protocols are defined.
* Add a single point for KPU profile loading, so that its source may
change in the future once proper interfaces for loading such config
are in place.

Since LD contains LTYPE definitions tweaked toward efficient
NIX_AF_RX_FLOW_KEY_ALG(0..31)_FIELD(0..4) usage, the original location
of NPC_LT_LD_CUSTOM0/1 was aliased with MPLS_IN_* definitions.
Moving custom frame to value 6 and 7 removes the aliasing at the cost of
custom frames being also considered when TCP/UDP RSS algo is configured.
However since the goal of CUSTOM frames is to classify them to a
separate set of RQs, this cost is acceptable.

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Refactor the code according to the use of a flexible-array member in
struct qed_ll2_tx_packet, instead of a one-element array and use the
struct_size() helper to calculate the size for the allocations. Commit
f5823fe6897c ("qed: Add ll2 option to limit the number of bds per packet")
was used as a reference point for these changes.
Also, it's important to notice that flexible-array members should occur
last in any structure, and structures containing such arrays and that
are members of other structures, must also occur last in the containing
structure. That's why _cur_completing_packet_ is now moved to the bottom
in struct qed_ll2_tx_queue. _descq_mem_ and _cur_send_packet_ are also
moved for unification.

When we set the BASET registers of i225 with a base_time in the
future, i225 will "hold" all packets until that base_time is reached,
causing a lot of TX Hangs.
As this behaviour seems contrary to the expectations of the IEEE
802.1Q standard (section 8.6.9, especially 8.6.9.4.5), let's start by
rejecting these types of schedules. If this is too limiting, we can
for example, setup a timer to configure the BASET registers closer to
the start time, only blocking the packets for a "short" while.

Many TSN features depend on the internal PTP clock, so the internal
PTP jumping when the adapter is reset can cause problems, usually in
the form of "TX Hangs" warnings in the driver.
The solution is to save the PTP time before a reset and restore it
after the reset is done. The value of the PTP time is saved before a
reset and we use the difference from CLOCK_MONOTONIC from reset time
to now, to correct what's going to be the new PTP time.
This is heavily inspired by commit bf4bf09bdd91 ("i40e: save PTP time
before a device reset").

Add XDP support to the IGB driver.
The implementation follows the IXGBE XDP implementation
closely and I used the following patches as basis:
1. commit 924708081629 ("ixgbe: add XDP support for pass and drop actions")
2. commit 33fdc82f0883 ("ixgbe: add support for XDP_TX action")
3. commit ed93a3987128 ("ixgbe: tweak page counting for XDP_REDIRECT")
Due to the hardware constraints of the devices using the
IGB driver we must share the TX queues with XDP which
means locking the TX queue for XDP.
I ran tests on an older device to get better numbers.
Test machine:
Intel(R) Atom(TM) CPU C2338 @ 1.74GHz (2 Cores)
2x Intel I211
Routing Original Driver Network Stack: 382 Kpps
Routing XDP Redirect (xdp_fwd_kern): 1.48 Mpps
XDP Drop: 1.48 Mpps
Using XDP we can achieve line rate forwarding even on
an older Intel Atom CPU.

Make use of the "shared port table" to convert i40e to the new
infra.
i40e did not have any reference tracking, locking is also dodgy
because rtnl gets released while talking to FW, so port may get
removed from the table while it's getting added etc.
On the good side i40e does not seem to be using the ports for
TX so we can remove the table from the driver state completely.

Set the speed optimization bit on the DP83869 PHY.
Speed optimization, also known as link downshift, enables fallback to 100M
operation after multiple consecutive failed attempts at Gigabit link
establishment. Such a case could occur if cabling with only four wires
(two twisted pairs) were connected instead of the standard cabling with
eight wires (four twisted pairs).
The number of failed link attempts before falling back to 100M operation is
configurable. By default, four failed link attempts are required before
falling back to 100M.
