b23896a221 if_ntb: Don't roundup MW size to full BAR size unnecessarily
Note that the MW allocation still must be BAR *aligned*.  So, this only
loosens the constraints on MW allocation slightly.  BAR-aligned does not
play well with large (GB+) BAR sizes.

Going forward, if anyone cares about if_ntb on very large BARs, I
suggest they add functionality to allocate a smaller window than the BAR
size, and set the BAR range to cover a window much larger than the
allocated window.  This will require negotiating a window offset and
limit for protocol traffic.  None of this is implemented in this
revision.

4cc8daf782 Pull vm_object_scan_all_shadowed out of vm_object_backing_scan
These two functions were largely unrelated, they just used the same same
loop logic to walk through a backing object's memq.  Pull out the
all_shadowed test as its own function and eliminate
OBSC_TEST_ALL_SHADOWED.  Rename vm_object_backing_scan to
vm_object_collapse_scan.

No functional change.

bde2a921d4 In assembler mode, clang defaulted to DWARF3, if only -g was specified.
Change this to DWARF2, in the simplest way possible.  (Upstream, this
was fixed in clang trunk r250173, but this was done along with a lot of
shuffling around of debug option handling, so it cannot be applied
as-is.)

484df459f0 newvers: Honour SOURCE_DATE_EPOCH as a build reproducibility measure
One reason the kernel does not build reproducibly is that it includes
a timestamp in the version string. SOURCE_DATE_EPOCH provides a standard
method to address this: it should be set to the last modification time
of the source, and build processes use the specified timestamp instead
of the "current" date and time.

This change uses SOURCE_DATE_EPOCH if it is set; how it gets set needs
to be addressed elsewhere.

14df39ad40 Add support for a generic AHCI attachment. This allows us to attach to a
typically memory mapped bus, for example on the AMD Opteron A1100 the AHCI
device is mapped in the CPUs address space, and not through a PCI
controller.

Further work is needed for this to work with ACPI as this is expected to be
common on ARMv8 servers.

27691a24ab For amd64 non-PCID machines, and for i386 machines with support for
the PG_G global pte flag, pmap_invalidate_all() fails to flush global
TLB entries [*].  This is because TLB shootdown handler for such
configs reloads CR3, and on i386 pmap_invalidate_all() does the same
for the initiating CPU.  Note that current code does not issue total
invalidation requests for the kernel_pmap.

Rename amd64 function invltlb_globpcid() to invltlb_glob(), it is not
specific for PCID for quite some time, and implement the same
functionality for i386.  Use the function instead of invltlb() in
shootdown handlers and in i386 pmap_invalidate_all(), but only for the
kernel pmap (which maps pages with the PG_G attribute set), which
takes care of PG_G TLB entries on flush.

To detect the affected pmap in i386 TLB shootdown handler, pmap should
be passed to the smp_masked_invltlb() function, which makes amd64 and
i386 TLB shootdown code almost identical.  Merge the code under x86/.

7aa69e3107 Disable EEE(Energy Efficient Ethernet) for RTL8211F PHY.
It seems the EEE made RX MAC enter LPI(Low Power Idle) mode such
that dwc(4) was not able to receive packets.  Ideally dwc(4) should
be able to use EEE to save power during periods of low link
utilization(i.e. gating off clock).  Due to lack of dwc(4)
datasheet it's not easy to take required steps for EEE on LPI
enter/exit events.  Disabling EEE in PHY seems to be easy
workaround until dwc(4) supports EEE.

Updating EEE advertisement register on RTL8211F seems to have no
effect until reprogramming MII_ANAR, MII_100T2CR and MII_BMCR
with auto-negotiation. It's not clear whether it's related with
mii_phy_reset()'s BMCR_ISO handling for RTL8211F though.
It seems rgephy_reset() needs careful investigation for newer
RealTek PHYs.

Ganbold submitted working version based on NetBSD change and
tested lots of changes I made. Thanks a lot!

fe2ebb7644 Add support for configuring additional virtual interfaces (VIs) on a port.
Each virtual interface has its own MAC address, queues, and statistics.
The dedicated netmap interfaces (ncxgbeX / ncxlX) were already implemented
as additional VIs on each port.  This change allows additional non-netmap
interfaces to be configured on each port.  Additional virtual interfaces
use the naming scheme vcxgbeX or vcxlX.

Additional VIs are enabled by setting the hw.cxgbe.num_vis tunable to a
value greater than 1 before loading the cxgbe(4) or cxl(4) driver.
NB: The first VI on each port is the "main" interface (cxgbeX or cxlX).

T4/T5 NICs provide a limited number of MAC addresses for each physical port.
As a result, a maximum of six VIs can be configured on each port (including
the "main" interface and the netmap interface when netmap is enabled).

One user-visible result is that when netmap is enabled, packets received
or transmitted via the netmap interface are no longer counted in the stats
for the "main" interface, but are not accounted to the netmap interface.

The netmap interfaces now also have a new-bus device and export various
information sysctl nodes via dev.n(cxgbe|cxl).X.

The cxgbetool 'clearstats' command clears the stats for all VIs on the
specified port along with the port's stats.  There is currently no way to
clear the stats of an individual VI.

8d7e0f5889 The cdevpriv_dtr_t typedef was not able to be used in a function prototype
like the various d_*_t typedefs since it declared a function pointer rather
than a function.  Add a new d_priv_dtor_t typedef that declares the function
and can be used as a function prototype.  The previous typedef wasn't
useful outside of the cdevpriv implementation, so retire it.

The name d_priv_dtor_t was chosen to be more consistent with cdev methods
since it is commonly used in place of d_close_t even though it is not a
direct pointer in struct cdevsw.
