This activates the CONFIG_SCHED_STACK_END_CHECK option.
The kernel will check if the kernel stack overflowed in the schedule()
function. This just adds a very small computational overhead.
This option is activated in Debian by default.

This activates some extra checks in SLAB or SLUB to make it harder to
execute kernel heap exploits. This adds a minor performance
degradation which I haven't measured-.
Many mainstream Linux distributions also activate this option.

This activates the following kernel options by default:
* CONFIG_RANDOM_TRUST_CPU
* CONFIG_RANDOM_TRUST_BOOTLOADER
With these option Linux will also use data from the CPU RNG e.g. RDRAND
and the bootloader to initialize the Linux RNG if such sources are
available.
These random bits are used in addition to the other sources, no other
sources are getting deactivated. I read that the Chacha mixer isn't
vulnerable to injected entropy, so this should not be a problem even if
these sources might inject bad random data.
The Linux kernel suggests to activate both options, Debian also
activates them. This does not increase kernel code size.

OpenWrt's developer guide prefers having actual patches so they an be
sent upstream more easily.
However, in the case of hack-5.15 patches which are not meant for
upstream, adding proper fields allows for `git am` to properly function.
This commit tries to rectify that, by digging in the history to find
where and how it was first added.

The previous attempt to replace an open coded paged read in the RealTek
Ethernet PHY driver was too naive and resulted in breaking the r8169
PCIe Ethernet driver which also makes use of the RealTek Ethernet PHY
driver.
Fix this by instead of using the (not yet populated) paged operations
rather use rtl821x_write_page and protect the whole paged read operation
using the MDIO bus mutex.

A patch was added in kernel 5.4 to support the fiber operation of
AR8033 with ramips devices. In kernel 5.18 similar enhancements
were added to the kernel. Those patches are required for other
fiber based devices but when added, build fails for ramips targets.
This commit removes the ramips patch and adds the kernel 5.18 ones.

* use interface mode switching only when operating in C45 mode
Linux prevents switching the interface mode when using C22 MDIO,
hence use rate-adapter mode in case the PHY controlled via C22.
* use phy_read_paged where appropriate
* use existing generic inline functions to handle 10GbE advertisements
instead of redundantly defining register macros in realtek.c which
are not actually vendor-specific.
* make sure 10GbE advertisement is valid, preventing false-positive
warning "Downshift occurred from negotiated speed 2.5Gbps to actual
speed 1Gbps, check cabling!" with some link-partners using 1G mode.
* Support Link Down Power Saving Mode (ALDPS)

MAC drivers don't use SGMII in-band autonegotiation unless told to do so
in device tree using 'managed = "in-band-status"'. When using MDIO to
access a PHY, in-band-status is unneeded as we have link-status via
MDIO. Switch off SGMII in-band autonegotiation using magic values.

Use sfp_quirk_2500basex for this module to allow 2500Base-X mode anyway.
