Check the right ifnet pointer to see if if_alloc() failed or not in
ef_clone(); we were testing the original ifnet, not the one allocated.
When aborting ef_clone() due to if_alloc() failing, free the allocated
efnet structure rather than leaking it.

When freeing the chain of if_ef devices on an aborted load, use
SLIST_FOREACH_SAFE() rather than SLIST_FOREACH(), as elements are
freed on each iteration of the loop. This prevents use-after-free.

- Move the command setup from amr_start1 into the card specific submit
routines.
- Add or replace cpu_spinwait() with DELAY(1) to a few of the busy
loops when reading from the controller to work around firmware bugs
which can crash the controller.

- Add loader(8) variables for RB_DFLTROOT, RB_MUTE, and RB_PAUSE:
"boot_dfltroot", "boot_mute", and "boot_pause" respectively.
- Cause all flags passed by boot2 to set the respective loader(8)
boot_* variable. The end effect is that all flags from boot2
are now passed to the kernel.

Reuse ktr_unused field in ktr_header structure as ktr_tid; populate
ktr_tid as part of gathering of ktr header data for new ktrace
records. The continued use of intptr_t is required for file layout
reasons, and cannot be changed to lwpid_t at this point.

Modify the IP fragment reassembly code so that it uses a new UMA zone,
ipq_zone, to allocate fragment headers from, rather than using cast mbuf
storage. This was one of the few remaining uses of mbuf storage for
local data structures that relied on dtom(). Implement the resource
limit on ipq's using UMA zone limits, but preserve current sysctl
semantics using a sysctl proc.

Add le(4), a driver for AMD Am7900 LANCE and Am79C9xx PCnet NICs,
ported from NetBSD.
This version differs from HEAD in that if_le_ledma.c inlines
lsi64854_enet_intr() from rev. 1.8 of sys/sparc64/sbus/lsi64854.c
in le_dma_hwintr() in order to not break the API of the LSI64854
driver in RELENG_6.

- Don't shift the clock frequency in MHz left by 8 before assigning it
to sbus_mdvec.dv_clock as sbus_mdvec.dv_clock is meant to be specified
in MHz. While this was a bug it shouldn't have affected FreeBSD/sparc64
as sbus_mdvec.dv_clock is used to limit the clock rate of chips when
a machine isn't able to support them at maximum speed which isn't the
case for sun4u machines.
- Remove the code that checks whether the clock frequency returned by
sbus_get_clockfreq() is 0 and falls back to 25MHz if it is as that's
already done in sbus(4).

there is no need in them doing so.

Avoid creating (and subsequently using) fake opt_*.h files
when the modules are built with the kernel and hence actual
opt_*.h files are available in ${KERNBUILDDIR}. Fix a few
small bugs that would prevent this from working.
At last the build options of the modules become consistent
with those of the kernel unless the MODULES_WITH_WORLD way
still is used.
