A (so far out-of-tree) driver update needs
request_partial_firmware_into_buf(). Given we load the full .ko file
using firmware(9) just do that and copy the requeste data into the
buffer (rather than poissibly only reading portions of the firmware
file).

Going through the Frame (Sub)types the "QOS Data" being called "QOS"
scheme leads to a naming conflict for QOS_CFPOLL and QOS_CFACKPOLL
(if added). Rename QOS* to QOS_DATA* to avoid the conflict and
to also better match the standards name.
No functional changes intended.

LinuxKPI: 802.11: add missing linuxkpi_cfg80211_bss_flush()
While working on new and updates to drivers more structs, fields,
functions, .. were found, had to be shuffled around, ..
Some of these are (so far still dummy) functions or not properly
typed fields. The IEEE80211_HE_ constants are all still dummy.
This was msotly as a start to make new (out-of-tree) things compile.

Add the missing implementation of linuxkpi_cfg80211_bss_flush().
without this we get unresolved symbols and drivers won't load.

RB_ROTATE_LEFT (and it symmetric twin) modify the rb-tree, adjusting
pointers so that what started as a proper tree ends up a proper
tree. When two consecutive rotations move the same node up the tree,
some of the pointers changed in the first rotation are immediately
changed again in the second - namely, the pointer from the rising node
to its new parent, and the pointer from that parent back to the rising
node. This change removes from RB_ROTATE macros the responsibility for
managing those two pointers, and leaves it to the code that calls for
rotations to fix up those pointers afterward. That drops a comparison
and a pair of assignments from every INSERT_COLOR or REMOVE_COLOR call
that ends in a double rotation.
A side-effect of this change is that the SWAP_CHILD macro must take as
a parameter a pointer to the node that is changing children, where it
is now computed from the old child. Since this macro is called in a
couple of places besides the RB_ROTATE macros, those calls are also
affected.

This is a joint work with manu.
- fixed conditions in do_i2c_transfer and i2c_transfer as linux_i2cbb
does not set adapter->algo->master_xfer but does set
adapter->algo_data;
- fixed parent bus specification for linux_i2cbb driver module;
- actually implemented iicbb_transfer method;
- added iicbb_pre_xfer and iicbb_post_xfer methods;
- removed unnecessary and harmful delays (and other extra logic) from
iicbb methods as iicbb driver already has them;
- added setting of iicbb speed based on algo_data->udelay, so that iicbb
uses correct delays;

Add i2c support to linuxkpi. 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).
