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.

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/.

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

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.

This also removes the need for some 'realinstall' hacks in bsd.subdir.mk since

I've been cautious about this commit but have experienced no breakage on the

Fix errors being ignored in many phases of the build since the bmake integration.
Say it with me, "I will not chain commands with && in Makefiles"

initial bmake integration caused 'set -e' to stop being used which lead to
r252419. Later 'set -e' expectations were fixed with bmake in r254980.
Because of the && here, errors would be ignored when building in parallel and
a dependency failed. Such as bootstrap-tools since it builds everything in
parallel. If any tool failed in obj/depend/all, it would just ignore the error
and continue to build. This later would result in cascaded errors that only
confused the real issue. This could also cause commands after the failed
command to still execute, leading to more confusion.
