The PPE driver registers its DSA switch, and with it attaches every user
port's PHY, before the root filesystem is mounted. A PHY driver that is
only available as a module therefore always loses the race:
phy_attach_direct() finds no matching driver, falls back to genphy_c45
and binds it with device_bind_driver(), and nothing rebinds the PHY when
the real driver shows up later.
On the boards with an Aquantia 10G PHY that leaves the AQR running under
the generic Clause 45 driver. It never loads its firmware, from the nvmem
cell or otherwise, and its system interface is never configured, so the
10G port does not pass traffic. Boards that provision the firmware from
flash have therefore never had that path execute at all.
The driver was built in until commit 8c3bcc198936 ("ipq807x: move AQR
driver from built-in to kmod"), which made it a module so that
IS_REACHABLE(CONFIG_HWMON) would evaluate true and the temperature
sensors in the AQR would be usable as thermal zones. That was correct at
the time: the ethernet driver then attached PHYs from userspace, so a
module was in place early enough, and hwmon was not built in.
Neither still holds. HWMON is compiled in on this target, so building the
PHY driver in keeps its hwmon support, and the PPE driver attaches PHYs
from its own probe. Build it in, as is already done for the AT803X and
QCA807X PHYs here.
CRC_ITU_T, which the driver selects for the firmware image
checksum, follows it from module to built-in.
Both symbols go in the ipq807x and ipq60xx config-default rather than
the target's per-kernel config. Every board with an AQR is on one of
those two subtargets and ipq50xx has none, and a subtarget's
config-default is merged for whichever kernel version the target
builds, so the 6.18 kernel picks them up as well.
kmod-phy-aquantia goes with it. The package builds empty once the symbol
is built in, because KernelPackage/install skips a module listed in
modules.builtin, but ModuleAutoLoad still runs and would ship
/etc/modules.d/18-phy-aquantia naming a module that no longer exists.
Drop it from the subtarget defaults and from the one ipq60xx device
that listed it, matching AT803X_PHY and QCA807X_PHY which carry no
kmod on this target.
