processor model.
No support for uncore events at this time.

Since ARP and routing are separated, "proxy only" entries
don't have any meaning, thus we don't need additional field
in sockaddr to pass SIN_PROXY flag.
New kernel is binary compatible with old tools, since sizes
of sockaddr_inarp and sockaddr_in match, and sa_family are
filled with same value.
The structure declaration is left for compatibility with
third party software, but in tree code no longer use it.

Right now, ic_curchan seems to be updated rather quickly (ie, during
the ioctl) and before the driver gets notified of what's going on.
So what I was seeing was:
* NIC was in channel X;
* It generates PHY errors for channel X;
* an ioctl comes along from userland and changes things to channel Y;
* .. this updates ic_curchan, but hasn't yet reset the hardware;
* in parallel, RX is occuring and it looks at ic_curchan;
* .. which is channel Y, so events get stamped with that now.
Sigh.
into the FreeBSD boot loader, typically for non-USB aware BIOSes, EFI systems
or embedded platforms. This is also useful for out of the system compilation
of the FreeBSD USB stack for various purposes. The USB kernel files can
now optionally include a global header file which should include all needed
definitions required to compile the FreeBSD USB stack. When the global USB
header file is included, no other USB header files will be included by
default.
Add new file containing the USB stack configuration for the
FreeBSD loader build.
Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all
USB files follow the same style.
Use cases:
- console in loader via USB
- loading kernel via USB

the code less confusing.
The blank lines are added to properly delineate the scope of the

timecounter to 1, and correspondingly increase the precision of the
gettimeofday(2) and related functions in the default configuration.
The motivation for the TSC-low timecounter, as described in the
r222866, seems to provide a workaround for the non-serializing
behaviour of the RDTSC on some Intel hardware. Tests demonstrate that
even with the pre-shift of 8, the cross-core non-monotonicity of the
RDTSC is still observed reliably, e.g. on the Nehalems. The r238755
and r238973 implemented the proper fix for the issue.
The pre-shift of 1 is applied to keep TSC not overflowing for the
frequency of hardclock down to 2 sec/intr. The pre-shift is made a
tunable to allow the easy debugging of the issues users could see with
the shift being too low.

bug in old versions of QEMU (and Xen, and other places using QEMU code).
On those buggy emulated UARTs, the "TX idle" interrupt gets lost; with
this workaround, we spinwait for the TX to happen and then send ourselves
the interrupt. It's ugly but it works, while minimizing the impact on
the code for the !broken_txfifo case.

In all the routines that loop through a range of virtual addresses, the loop
is controlled by subtracting the cache line size from the total length of the
request. After the subtract, a 'bpl' instruction was used, which branches if
the result of the subtraction is zero or greater, but we need to exit the
loop when the count hits zero. Thus, all the bpl instructions in those loops
have been changed to 'bhi' (branch if greater than zero).
In addition, the two routines that walk through the cache using set-and-index
were correct, but confusing. The loop control for those has been simplified,
just so that it's easier to see by examination that the code is correct.
Routines for other arm architectures and generations still have the bpl
instruction, but compensate for the off-by-one situation by decrementing
the count register by one before entering the loop.

If a BUSDMA load operation results in a single segment which
is greater than the PAGE_SIZE, the USB computed physical
addresses will not be correct. Make sure that the first
segment is unfolded like the sub-sequent segments are into
USB_PAGE_SIZE big ranges.
