This patch introduces ast2400/2500 phy-handle support with an embedded

with this format on ast2400/2500:

mac {
	phy-handle = <&phy>;
	phy-mode = "rgmii";

	mdio {
		#address-cells = <1>;
		#size-cells = <0>;

		phy: ethernet-phy@0 {
			compatible = "ethernet-phy-idxxxx.yyyy";
			reg = <0>;
		};
	};
};

The patch fixes it and gets possible PHYs and register them with
of_mdiobus_register.

Changes from v3:
   1. add dt-bindings description of MDIO node and phy-handle option
      with example.

Changes from v2:

To allow better problem diagnosis the return codes for SMC-Dv2 are
improved by this patch. A few more CLC DECLINE codes are defined and
sent to the peer when an SMC connection cannot be established.
There are now multiple SMC variations that are offered by the client and
the server may encounter problems to initialize all of them.
Because only one diagnosis code can be sent to the client the decision
was made to send the first code that was encountered. Because the server
tries the variations in the order of importance (SMC-Dv2, SMC-D, SMC-R)
this makes sure that the diagnosis code of the most important variation
is sent.

====================
Support for OcteonTx2 98xx silicon

OcteonTx2 series of silicons have multiple variants, the
98xx variant has two network interface controllers (NIX blocks)
each of which supports upto 100Gbps. Similarly 98xx supports
two crypto blocks (CPT) to double the crypto performance.
The current RVU drivers support a single NIX and
CPT blocks, this patchset adds support for multiple
blocks of same type to be active at the same time.

Also the number of serdes controllers (CGX) have increased
from three to five on 98xx. Each of the CGX block supports
upto 4 physical interfaces depending on the serdes mode ie
upto 20 physical interfaces. At a time each CGX block can
be mapped to a single NIX. The HW configuration to map CGX
and NIX blocks is done by firmware.

NPC has two new interfaces added NIX1_RX and NIX1_TX
similar to NIX0 interfaces. Also MCAM entries is increased
from 4k to 16k. To support the 16k entries extended set
is added in hardware which are at completely different
register offsets. Fortunately new constant registers
can be read to figure out the extended set is present
or not.

This patch set modifies existing AF and PF drivers
in below order to support 98xx:
- Prepare for supporting multiple blocks of same type.
  Functions which operate with block type to get or set
  resources count are modified to operate with block address
- Manage allocating and freeing LFs from new NIX1 and CPT1 RVU blocks.
- NIX block specific initialization and teardown for NIX1
- Based on the mapping set by Firmware, assign the NIX block
  LFs to a PF/VF.
- Multicast entries context is setup for NIX1 along with NIX0
- NPC changes to support extended set of MCAM entries, counters
  and NIX1 interfaces to NPC.
- All the mailbox changes required for the new blocks in 98xx.
- Since there are more CGX links in 98xx the hardcoded LBK
  link value needed by netdev drivers is not sufficient any
  more. Hence AF consumers need to get the number of all links
  and calculate the LBK link.
- Debugfs changes to display NIX1 contexts similar to NIX0
- Debugfs change to display mapping between CGX, NIX and PF.

Unlike earlier silicon variants, OcteonTx2 98xx
silicon has 2 NIX blocks and each of the CGX is
mapped to either of the NIX blocks. Each NIX
block supports 100G. Mapping btw NIX blocks and
CGX is done by firmware based on CGX speed config
to have a maximum possible network bandwidth.
Since the mapping is not fixed, it's difficult
for a user to figure out. Hence added a debugfs
entry which displays mapping between CGX LMAC,
NIX block and RVU PF.

This patch puts together all mailbox changes
for 98xx silicon:

Attach ->
Modify resource attach mailbox handler to
request LFs from a block address out of multiple
blocks of same type. If a PF/VF need LFs from two
blocks of same type then attach mbox should be
called twice.

Example:
        struct rsrc_attach *attach;
        .. Allocate memory for message ..
        attach->cptlfs = 3; /* 3 LFs from CPT0 */
        .. Send message ..
        .. Allocate memory for message ..
        attach->modify = 1;
        attach->cpt_blkaddr = BLKADDR_CPT1;
        attach->cptlfs = 2; /* 2 LFs from CPT1 */
        .. Send message ..

Detach ->
Update detach mailbox and its handler to detach
resources from CPT1 and NIX1 blocks.

MSIX ->
Updated the MSIX mailbox and its handler to return
MSIX offsets for the new block CPT1.

Free resources ->
Update free_rsrc mailbox and its handler to return
the free resources count of new blocks NIX1 and CPT1

Links ->
Number of CGX,LBK and SDP links may vary between
platforms. For example, in 98xx number of CGX and LBK
links are more than 96xx. Hence the info about number
of links present in hardware is useful for consumers to
request link configuration properly. This patch sends
this info in nix_lf_alloc_rsp.

Since multiple blocks of same type are present in
98xx, modify functions which get resource count and
which update resource count to work with individual
block address instead of block type.

Update the axienet driver to properly support the Xilinx PCS/PMA PHY
component which is used for 1000BaseX and SGMII modes, including
properly configuring the auto-negotiation mode of the PHY and reading
the negotiated state from the PHY.

The previous commit added support for IPA having up to six source
and destination resources.  But currently nothing uses more than
four.  (Five of each are used in a newer version of the hardware.)

I find that in one of my build environments the compiler complains
about newly-added code in two spots.  Inspection shows that the
warnings have no merit, but this compiler does not recognize that.

    ipa_main.c:457:39: warning: array index 5 is past the end of the
        array (which contains 4 elements) [-Warray-bounds]
    (and the same warning at line 483)

We can make this warning go away by changing the number of elements
in the source and destination resource limit arrays--now rather than
waiting until we need it to support the newer hardware.  This change
was coming soon anyway; make it now to get rid of the warning.

====================
net: add functionality to net core byte/packet counters and use it in r8169

This series adds missing functionality to the net core handling of
byte/packet counters and statistics. The extensions are then used
to remove private rx/tx byte/packet counters in r8169 driver.

After switching to the net core rx/tx byte/packet counters we can
remove the now unused private version.

Switch to the net core rx/tx byte/packet counter infrastructure.
This simplifies the code, only small drawback is some memory overhead
because we use just one queue, but allocate the counters per cpu.
