These simple attributes are an essential component for compiling drm-kmod with CONFIG_DEBUG_FS enabled. This will allow for easier graphics driver debugging using Intel's igt-gpu-tools.

In order for the include list to be expanded more easily in the future, e.g., adding the "dummy" includes (for all) and to harmonize code, duplicate LINUXKPI_INCLUDES to kmod.mk and use it for all module Makefiles.

This is needed by drm-kmod. For every i2c_adapter added by i2c_add_adapter we add a child to the device named "lkpi_iic". This child handle the conversion between Linux i2c_msgs to FreeBSD iic_msgs. For every i2c_adapter added by i2c_bit_add_bus we add a child to the device named "lkpi_iicbb". This child handle the conversion between Linux i2c_msgs to FreeBSD iic_msgs. With the help of iic(4), this expose the i2c controller to userspace allowing a user to query DDC information from a monitor. e.g.: i2c -f /dev/iic0 -a 0x28 -c 128 -d r will query the standard EDID from the monitor if plugged. The bitbang part (lkpi_iicbb) isn't tested at all for now as I don't have compatible hardware (all my hardware have native i2c controller).

Along add a (for now) task based NAPI implementation. This is the minimal set of chnages which are needed for the initial support of wireless drivers. The NAPI implementation has an option to still switch to "direct dispatch" as it had been used by these drivers before not relying on a deferred context along with some printf tracing. This has been helpful in the last weeks for debugging and will be cleaned once we have had broader testing and are sure this is fine as-is. Should we need a more time-sensitive or load-sensitive response in the future we can always switch to something more sophisticated.

Bring in this version of the code as it has proven to be good enough to have packets going for a few months. The current implementation has several drawbacks including the need for us to copy data between sk_buffs and mbufs. Do not rely on the internals of this implementation. They are highly likely to change as we will improve the integration to FreeBSD mbufs.

Part of the framework replicates the consumed KPI, while others are internal helper functions. In addition the simple devm_k*malloc() consumers were implemented and kvasprintf() was enhanced to also work for the devm_kasprintf() case. Addmittingly lkpi_devm_kmalloc_release() could be avoided but for the overall understanding of the code and possible memory tracing it may still be helpful. Further devsres consumer are implemented for iwlwifi but will follow later as the main reason for this change is to sort out overlap with DRM.
