Use our ifm_list of supported media types rather than nested switch
statements to find the current media type. Find a supported type that
matches the current speed.
Remove all workarounds while updating ifmr->ifm_active.
For BNXT_IFMEDIA_ADD, added Three more speeds IFM_10G_T, IFM_2500_T & IFM_2500_KX.

Preserve packet order between tcp_lro_rx() and if_input() to avoid
creating extra corner cases. If no packets can be LROed, combine them
into one chain for submission via if_input(). If any packet can
potentially be LROed however, retain old behaviour and call if_input()
for each packet.
This should keep the 12% improvement for small packet forwarding intact,
but mostly avoids impacting the LRO case.

Final sweep to prefer bsd.init.mk to src.opts.mk everywhere as a
design pattern. The rule is that all Makefiles in this subtree should
start with .include <bsd.init.mk> so that we properly include
../Makefile.inc and defs.mk before anything else.

Steal the code from kmod.mk and use it to automatically create
links. Modify it a little for the needs of the loader (no need to
guess the OBJS dependency, and we have 32-on-64 cases to contend
with). Remove 15 redundant implementations (which were mostly
different, but kinda the same).
A future commit should factor out this code and that of kmod.mk so we
have only one copy of it in the tree.

Stop building libsa32 on powerpc. Build everything on powerpc64
-m32. Transition to using LIBSA from LIBSA32. This elimiantes the
useless build of libsa on powerpc64 (nothing used to use it) and
should be a more direct way of saying this.

Since the case of an empty chain was already covered, it si very likely
that the existing entry is matching. Skipping readlocking saves on lock
upgrade.
When the segment count is > 16 it spills into an 'indirect descriptor list',
which immediately follows the main table, but the indirect list is entry 15, so
needs to be skipped for the general list.
Failure modes of the modern (that is, produced in the last 25 years)
hard drives and SSDs made the utility outdated. Since the kernel
interface to support it was removed in r324853, cut the userspace
remnants as well.

Otherwise an orderly shutdown will initiate a watchdog that will cause
a 7 minute delayed reboot *by default*, In the freebsd.org cluster's case
this often worked out be a surprise reboot a minute or two after the
machine came back up.
The Freescale SATA controller has many similarities to AHCI controllers, so
this driver is a heavily modified AHCI driver. Currently it seems to only
do SATA 1.0 speeds (~100-150MB/s), so there is still room for improvement.
Still to be done:
* Address erratum SATA-A-006187 -- Spread Spectrum Support (intermittent
non-recoverable transient data integrity error seen when SSC enabled).
* Linux doesn't read the log page as it hangs on the P1022. See if that's
applicable to this, and address accordingly.
* Try to determine what's holding back performance, and address it.

Under certain traffic pattern awg driver does not recover from TX queue
full condition. The actual source of the problem is not identified yet
but jmcneill@ agreed that bumping TX_MAX_SEGS to 20 is OK as a workaround
for the problem (NetBSD has it set to 128).
Also add some diagnostic printfs to prevent silent failure of bus_dma
functions in the future
PR will be kept open until root cause of the issue is identified and fixed

We already pass -many to the assembler, and -me500 drops 64-bit instruction
handling, for some reason only breaking module building for 64-bit kernels.
Additionally, build with CTF for dtrace.
NO_OBJ has a very specific meaning in sub-directories in that no object
directory will be made. If a user wanted to skip the 'make obj' phase then
passing -DNO_OBJ would break all sub-directories from building properly. Using
NO_OBJ internally also causes issue with NO_OBJ handling being added in
share/mk/bsd.init.mk soon.

If _mapping_process_dpm_pg0 detects inconsistencies in the drive
mapping table (stored in the HBA's NVRAM), abort reading it and

instead of malloc(). The SWAP objects are automagically freed when there are no
more consumers. This greatly simplifies the mmap logic inside CUSE(3) in the
kernel. This change fixes an issue where mmapped memory can accumulate and never
get freed, if many different mmap sizes are needed over time. Further this
change fixes memory leaks when the CUSE(3) kernel module is unloaded.
While at it make sure the CUSE_ALLOC_PAGES_MAX limit is treated as an exclusive
limit. CUSE(3) memory maps must be less than CUSE_ALLOC_PAGES_MAX number of pages.

This pointer is checked during the linux_dev_open() callback and does
not need to be NULL checked again. It should always be set for
character devices belonging to the "linuxcdevsw" and technically
there is no need to NULL check this pointer at all.
