The generic support in netmap send the packets using if_transmit() and the
loopback do not support packets coming from if_transmit()/if_start().
This avoids the use of the loopback interface and the subsequent crash that
happens when the application send packets to the loopback interface.

mps_wait_command() and mpr_wait_command() were using getmicrotime() to
determine elapsed time when checking for a timeout in polled mode.
getmicrotime() isn't guaranteed to monotonically increase, and that
caused spurious timeouts occasionally.
Switch to using getmicrouptime(), which does increase monotonically.
This fixes the spurious timeouts in my test case.

From the original commit:
==
* Actually look at the first channel in the list. If it's a 2.4GHz channel,
set IWM_PHY_BAND_24 flag. The IWM_PHY_BAND_5 flag is 0 anyway, so we
don't need to look further.
* While there factor out the iwm_mvm_rrm_scan_needed() tlv capability check.

However, this only really does the latter. The sc_ic channel list isn't the
scan channel list, it's the /whole list/ for the set of active channels,
so I don't know what the right thing to do is here.
So I'll commit this as an intermediary commit and we'll have to revisit whether
to finish the refactor as-is.

* Intel 7260, STA mode

- Deal with changes to port_type, and not just port_mod when a
transceiver is changed. This fixes hot swapping of transceivers of
different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or
SFP28 in a SFP28 port, etc.).
- Always refresh media information for ifconfig if the port is down.
The firmware does not generate tranceiver-change interrupts unless at
least one VI is enabled on the physical port. Before this change
ifconfig diplayed potentially stale information for ports that were
administratively down.
- Always recalculate and reapply L1 config on a transceiver change.
- Display PAUSE settings in ifconfig. The driver sysctls for this
continue to work as well.

From Brett:
In short, busdma maps for received packets were not being unloaded in the
interrupt handler before the packets were passed up the network stack. The fix
was to add a busdma sync and unload for the two receive maps.
This bug is significant for certain busdma providers, for example IOMMUs,
where not unloading the maps means that 1) the IOMMU mappings that allow the
NIC to DMA the received packets into host memory stay open indefinitely,
potentially violating a desired security policy, and 2) resources such as
device address space addresses and host memory for bookkeeping are never freed.
Without an IOMMU or bounce buffering enabled for the ixl device, I don't think
adding these calls will have any significant performance impact. With the
IOMMU enabled, I have noticed a performance impact on the receive side, which
is expected.

code was used, so the lightness bit was not flipped, so the flipping
was unnecessarily null in some cases. E.g., the unusal color scheme
of lightwhite on white (white = lightgrey in kernelspeak) is not
completely unusable, except null flipping of it gave no visible marks
for cut marking. Now flipping it works in pixel mode only.
Fix text cursor attribute adjustment over cut marking in text mode for
the usual cursor type (non-blinking full block). Apply the flipping
for cut marking first and adjust that instead of vice versa. This
gives a uniform color scheme for the usual text cursor type in text
mode: a white block background with no change to the character
foreground except for variations to avoid collisions. The old order
gave a white character fg with no change in the bg in non-colliding
cases. Versions before r316636 changed the bg to the non-cut-marked
one about half the time using a saveunder bug; this accidentally gave
something resembling a block cursor half the time.

Implement the MMC/SD/SDIO protocol within a CAM framework. CAM's
flexible queueing will make it easier to write non-storage drivers
than the legacy stack. SDIO drivers from both the kernel and as
userland daemons are possible, though much of that functionality will
come later.
Some of the CAM integration isn't complete (there are sleeps in the
device probe state machine, for example), but those minor issues can
be improved in-tree more easily than out of tree and shouldn't gate
progress on other fronts. Appologies to reviews if specific items
have been overlooked.

Access to the dri device gives effectively access to the entire memory of the machine (you can program

For current/stable/release this is a NOP, as access to memory is not allowed in a jail. This puts the dri

to choose the best one.
The old 9x13 cursor was was sort of correct for CGA 640x200 text mode,
but distorted for all other modes. This mode is still available on
all systems with VGA, but stopped being useful in ~1985. It has very
unsquare pixels with an aspect ratio of 240:100 on 4:3 monitors. On
16:9 monitors, the unsquareness in this mode is reduced to only 180:100
iff the monitor stretches the pixels to the full screen.
Newer modes and systems have smaller distortions, but with many more
variations. Square pixels first became common with VGA 640x480 mode
on 4:3 monitors. However, standard VGA text mode also has 9-bit wide
characters and only 25 lines, so it has 720x400 pixels. This has
unsquare pixels with an aspect ratio of 135:100 on 4:3 monitors. On
16:9 monitors, it gives almost-square pixels with an aspect ration of
101:100 iff the monitor stretches, but in modes that were square on
4:3 monitors square similar monitor stretching breaks the squareness.
Guess the physical aspect ratio using heuristics. The old version of
X that I use is further from doing this using info from PnP monitors
that is unavailable in syscons (X doesn't understand if the monitor
is doing stretching and doesn't even understand how its its own mode
changes affect the pixel size). Monitors with aspect ratio control
should be configured to _not_ stretch 4:3 modes to 16:9. Otherwise,
use the machdep.vga_aspect_scale sysctl to compensate. Only 1 of my
4 monitors/laptops requires this. It always stretches to 16:9.
The mouse data has new aspect ratio fields for selecting the best
cursor and a new name field for display in debugging messages.
Selecting the mouse cursor is now a slow operation so it is not done
for every drawing of the cursor. To avoid a new initialization method,
it is done whenever the text cursor is set or changed. Also remove
dead code in settings of text cursors.
Use larger mouse cursors (sometimes the full 10x16 one) for 8x8 fonts
in cases where this works better (mostly in graphics mode).
To mostly fix distortion of mouse cursors by non-square pixels, I
needed 8 variants of the same cursor shape for large fonts and
another 7 variants for small fonts. Some variants are shared,
leaving only 13 variants in 26 glyphs altogether. Keep these in
the BDF source file cursor.bdf. cursor.bdf has another 5 unused
experimental cursors in 10 glyphs. cursor.awk is a simple awk
script for converting this and similar bdf files into C declarations
for copying into scvgarndr.c. syscons doesn't use any of this yet.
