success and a good value. Only then try to use it and set the MSIX_ENABLE
bit.
With the current em(4) driver we have observed failures in this case in a
specific environment when pci_find_cap() would not return the assumed
value, which meant we ended up writing to PCI register 2 (PCI_DEVICE_ID)
which is read-only.

This commit introduces following changes in order to get rid of
ifdef's from all around the driver.
* Introduce sc_soc_id field in cesa_softc structure - this value is
obtained in cesa_attach() anyway, so make use of it.
* Replace ifdefs with SoC ID checks.
* Perform PM control status only for relevant SoC's.

HWPMC_HOOKS is enabled in GENERIC and triggers some work avoidable in the
common (module not loaded) case.
In particular this avoids permission checks + lock downgrade
singlethreaded and in cases were an executable mapping is found the pmc
sx lock is no longer bounced.
Note this is a band aid.

Add additionally safety and overflow checks to clock_ts_to_ct and the

Perform a safety check in sys_clock_settime() first to avoid easy local

Add internal tracking of smp startup status to reliably figure out
what methods are to be used to get gtaskqueue up and running.
e1000:
Calculating this pointer gives undefined behaviour when (last == -1)
(it is before the buffer). The pointer is always followed. Panics
occurred when it points to an unmapped page. Otherwise, the pointed-to
garbage tends to not have the E1000_TXD_STAT_DD bit set in it, so in the
broken case the loop was usually null and the function just returned, and
this was acidentally correct.

If "capacity" LU option is set, ramdisk backend now implements featured
thin provisioned disk, storing data in malloc(9) allocated memory blocks
of pblocksize bytes (default PAGE_SIZE or 4KB). Additionally ~0.2% of LU
size is used for indirection tree (bigger pblocksize reduce the overhead).
Backend supports all unmap and anchor operations. If configured capacity
is overflowed, proper error conditions are reported.
If "capacity" LU option is not set, the backend operates mostly the same
as before without allocating real storage: writes go to nowhere, reads
return zeroes, reporting that all LBAs are unmapped.
This backend is still mostly oriented on testing and benchmarking (it is
still a volatile RAM disk), but now it should allow to run real FS tests,
not only simple dumb dd.

Hyper-V's NIC SR-IOV implementation needs a Hyper-V synthetic NIC and
a VF NIC to work together (both NICs have the same MAC address), mainly to
support seamless live migration.
When the VF device becomes UP (or DOWN), the synthetic NIC driver needs
to switch the data path from the synthetic NIC to the VF (or the opposite).
Note: multicast/broadcast packets are still received through the synthetic
NIC and we need to inject the packets through the VF interface (if the VF is
UP), even if the synthetic NIC is DOWN (so we need to force the rxfilter
to be NDIS_PACKET_TYPE_PROMISCUOUS, when the VF is UP).

It's unnecessary because the upper nework stack does the same checking.
In the case of Hyper-V SR-IOV, we need to remove the checking because
1) multicast/broadcast packets are still received through the synthetic
NIC and we need to inject the packets through the VF interface;
2) we must inject the packets even if the synthetic NIC is down, or has
a different MTU from the VF device.

Variables "fast" and "active" are both constant in lacp_port_create(), but
comments mispleadingly suggest that "fast" can be changed via ioctl. The
constant values control the value of "lp->lp_state", so it too is constant,
and the code for assigning different value to it is essentially dead.
Remove both "fast" and "active", and set "lp->lp_state" unconditionally;
that gets rid of the dead code and misleading comments.
