Unlike bwi(4), bwn(4) does not rely on ic_headroom (despite having it
set) but splits the bwn_txhdr (first) segment into its own transaction.
Remove ic_headroom to avoid net80211 troubles with not enough space in
the mbuf around ieee80211_mbuf_adjust().

(cherry picked from commit 59dba901f227420647e4856f03cb782a3375c220)
Fix defines and structures to use proper types.
Bring in basic ni->sta synchronization, some channel width handling,
and overload the net80211 functions so that we can talk to
driver/firmware to setup parameters. We will likely not need one
or two of those but it is good for tracing currently.
Cover HT and bits of VHT code in LinuxKPI behind apropriate #ifdef
which are currently not enabled (like LKPI_80211_HW_CRYPTO) until
confirmed to work.
Last, IEEE80211_AMPDU_RX_START made some firmware unhappy.
This will allow others to work on it and test as well.

Move the net_epoch into net80211 around the if_input calls and out of
the driver (in this first case LinuxKPI). This reduces coverage but
also allows us to alloc in calls like (*ampdu_rx_start) which do not
actually pass data up the stack.

21c4082de9,

Both drivers are not yet attached to the build so this change is
for people currently trying them out.
In 96ab16ebab6319dce9b3041961b0ab6e20a4fecc the sys/rman.h include
was removed. In various wireless drivers we prefer to directly use
bus_dma functions rather than io* LinuxKPI once. In order to cast
the pointer we need sys/rman.h back for our native 'struct resource'
in their pci.c implementations.
Long-term we should consider providing some lkpi_-FreeBSD-specific
wrapper functions to avoid this problem.

Start scaling arrays dynamically instead of using MAXCPU, resulting in
extra allocations on startup but reducing the overall memory footprint.
For the static single CPU mask we provide two versions to further save
memory depending on a low or high CPU count system. The threshold to
switch is currently at 128 CPUs on 64bit platforms.
More detailed comments on the implementations can be found in the code.
If I am not wrong on a MAXCPU=65536 system the memory footprint should
roughly go down from 512M to 1.5M for the static single CPU mask.

Amdgpu driver does a lot of memory allocations in FPU-protected sections
of code for certain display cores, e.g. for DCN30. This does not work
on FreeBSD as its malloc function can not be run within a critical
section. Check this condition and temporally exit from FPU-protected
context to workaround issue and reduce source code patching.
