The UDP reuseport conflict was a little bit tricky.
The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.
At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.
This requires moving the reuseport_has_conns() logic into the callers.

After the patch below, the iteration through the available MMDs is
completely short-circuited, and devs_in_pkg remains set to the initial
value of zero.
Due to devs_in_pkg being zero, the rest of get_phy_c45_ids() is
short-circuited too: the following loop never reaches below this point
either (it executes "continue" for every device in package, failing to
retrieve PHY ID for any of them):
/* Now probe Device Identifiers for each device present. */
for (i = 1; i < num_ids; i++) {
if (!(devs_in_pkg & (1 << i)))
continue;
So c45_ids->device_ids remains populated with zeroes. This causes an
Aquantia AQR412 PHY (same as any C45 PHY would, in fact) to be probed by
the Generic PHY driver.
The issue seems to be a case of submitting partially committed work (and
therefore testing something other than was submitted).
The intention of the patch was to delay exiting the loop until one more
condition is reached (the devs_in_pkg read from hardware is either 0, OR
mostly f's). So fix the patch to reflect that.
Tested with traffic on a LS1028A-QDS, the PHY is now probed correctly
using the Aquantia driver. The devs_in_pkg bit field is set to
0xe000009a, and the MMDs that are present have the following IDs:

With PCS support, how we implement interface reconfiguration (or other
major reconfiguration) is not up to the job; we end up reconfiguring
the PCS for an interface change while the link could potentially be up.
In order to solve this, add two additional MAC methods for major
configuration, one to prepare for the change, and one to finish the
change.
This allows mvneta and mvpp2 to shutdown what they require prior to the
MAC and PCS configuration calls, and then restart as appropriate.
This impacts ksettings_set(), which now needs to identify whether the
change is a minor tweak to the advertisement masks or whether the
interface mode has changed, and call the appropriate function for that
update.

Comparing the ethtool output from phylink and non-phylink fixed-link
setups shows that we have some differences:
- The "auto-negotiation" fields are different; phylink reports these
as "No", non-phylink reports these as "Yes" for the supported and
advertising masks.
- The link partner advertisement is set to the link speed with non-
phylink, but phylink leaves this unset, causing all link partner
fields to be omitted.
The phylink ethtool output also disagrees with the software emulated
PHY dump via the MII registers.
Update the phylink fixed-link parsing code so that we better reflect
the behaviour of the non-phylink code that this facility replaces, and
bring the ethtool interface more into line with the report from via the

At the time of introduction, in commit bdeced75b1 ("net: dsa: felix:
Add PCS operations for PHYLINK"), support for the Lynx PCS inside Felix
was relying, for USXGMII support, on the fact that get_phy_device() is
able to parse the Lynx PCS "device-in-package" registers for this C45
MDIO device and identify it correctly.
However, this was actually working somewhat by mistake (in the sense
that, even though it was detected, it was detected for the wrong
reasons).
The get_phy_c45_ids() function works by iterating through all MMDs
starting from 1 (MDIO_MMD_PMAPMD) and stops at the first one which
returns a non-zero value in the "device-in-package" register pair,
proceeding to see what that non-zero value is.
For the Felix PCS, the first MMD (1, for the PMA/PMD) returns a non-zero
value of 0xffffffff in the "device-in-package" registers. There is a
code branch which is supposed to treat this case and flag it as wrong,
and normally, this would have caught my attention when adding initial
support for this PCS:
if ((devs_in_pkg & 0x1fffffff) == 0x1fffffff) {
/* If mostly Fs, there is no device there, then let's probe
* MMD 0, as some 10G PHYs have zero Devices In package,
* e.g. Cortina CS4315/CS4340 PHY.
*/
However, this code never actually kicked in, it seems, because this
snippet from get_phy_c45_devs_in_pkg() was basically sabotaging itself,
by returning 0xfffffffe instead of 0xffffffff:
/* Bit 0 doesn't represent a device, it indicates c22 regs presence */
*devices_in_package &= ~BIT(0);
Then the rest of the code just carried on thinking "ok, MMD 1 (PMA/PMD)
says that there are 31 devices in that package, each having a device id
of ffff:ffff, that's perfectly fine, let's go ahead and probe this PHY
device".
But after cleanup commit 320ed3bf90 ("net: phy: split
devices_in_package"), this got "fixed", and now devs_in_pkg is no longer
0xfffffffe, but 0xffffffff. So now, get_phy_device is returning -ENODEV
for the Lynx PCS, because the semantics have remained mostly unchanged:
the loop stops at the first MMD that returns a non-zero value, and that
is MMD 1.
But the Lynx PCS is simply a clause 37 PCS which implements the required
MAC-side functionality for USXGMII (when operated in C45 mode, which is
where C45 devices-in-package detection is relevant to). Of course it
will fail the PMD/PMA test (MMD 1), since it is not a PHY. But it does
implement detection for MDIO_MMD_PCS (3):
- MDIO_DEVS1=0x008a, MDIO_DEVS2=0x0000,
- MDIO_DEVID1=0x0083, MDIO_DEVID2=0xe400
Let get_phy_c45_ids() continue searching for valid MMDs, and don't
assume that every phy_device has a PMA/PMD MMD implemented.

To ensure that the octeon MDIO driver has been loaded, the Cavium
ethernet drivers reference a dummy symbol in the MDIO driver. This
forces it to be loaded first. And this symbol has not been cleanly
implemented, resulting in warnings when build W=1 C=1.
Since device tree is being used, and a phandle points to the PHY on
the MDIO bus, we can make use of deferred probing. If the PHY fails to
connect, it should be because the MDIO bus driver has not loaded
yet. Return -EPROBE_DEFER so it will be tried again later.
Additionally, add a MODULE_SOFTDEP() to give user space a hint as to
what order it should load the modules.
v2:
s/octoen/octeon/
Add MODULE_SOFTDEP()

The MIPS low level register access functions seem to be missing
__iomem annotation. This causes lots of sparse warnings, when code
casts off the __iomem. Make the Cavium MDIO drivers cleaner by pushing
the casts lower down into the helpers, allow the drivers to work as
normal, with __iomem.
bus->register_base is now an void *, rather than a u64. So forming the
mii_bus->id string cannot use %llx any more. Use %px, so this kernel
address is still exposed to user space, as it was before.

Avoid the W=1 warning that symbol 'genphy_c45_driver' was not
declared. Should it be static?
Declare it on the phy header file.

By placing the GENMASK value into an unsigned int and then passing it
to PREF_FIELD, the type is reduces down from ULL. Given the reduced
size of the type, the range checks in PREP_FAIL() are always true, and
-Wtype-limits then gives a warning.
By skipping the intermediate variable, the warning can be avoided.

Dynamically generate a unique GPIO interrupt name, based on the
device name and the GPIO name. For example:
103: 0 sx1503q 12 Edge sff2-los
104: 0 sx1503q 13 Edge sff2-tx-fault
The sffX indicates the SFP the los and tx-fault are associated with.
v3:
- reverse Christmas tree new variable
- fix spaces vs tabs
v2:
- added net-next to PATCH part of subject line
- switched to devm_kasprintf()

Implement a managed variant of of_mdiobus_register(). We need to make
mdio_devres into its own module because otherwise we'd hit circular
sumbol dependencies between phylib and of_mdio.
