virtual address size configured by the kernel. For example, with a
virtual address size of 48, the PAC is 7 bits wide.
Recent versions of GCC can compile code with APIAKey-based return
address protection when passed the -msign-return-address option. This
uses instructions in the HINT space (unless -march=armv8.3-a or higher
is also passed), and such code can run on systems without the pointer
authentication extension.
When ARM64_PTR_AUTH_KERNEL is selected, the kernel will be compiled
with HINT space pointer authentication instructions protecting
function returns. Kernels built with this option will work on hardware
with or without pointer authentication support.
In addition to exec(), keys can also be reinitialized to random values

NBASE-T Support
---------------
The ixgbe driver supports NBASE-T on some devices. However, the advertisement
of NBASE-T speeds is suppressed by default, to accommodate broken network
switches which cannot cope with advertised NBASE-T speeds. Use the ethtool
command to enable advertising NBASE-T speeds on devices which support it::
