By default, vt(4) gets the "preferred mode" from DRM, when using a DRM
video driver as its backend. The preferred mode is usually the native
screen resolution.
Now, if this mode isn't appropriate, a user can use loader tunables to
select a mode. The tunables are read in the following order:
1. kern.vt.fb.modes.$connector_name
2. kern.vt.fb.default_mode
For example, to set a 1024x768 mode, no matter the connector:
kern.vt.fb.default_mode="1024x768"
To set a 800x600 mode only on the laptop builtin screen:
kern.vt.fb.modes.LVDS-1="800x600"
Beside r274031, this MFC includes:
r274049:
drm: When reading connector mode tunables, list connectors
... and their associated tunables. This gives a way to know the list of
available connectors, no matter the driver.
The problem is that xrandr(1) can list connectors but it uses a
different naming.
r274050:
vt(4): Document kern.vt.fb.default_mode and kern.vt.fb.modes.*
Those tunables are used to set a specific mode in vt(4) instead of using
the default mode.

The problem was that only the kbdmux keyboard index was saved in
vd->vd_keyboard. This index is -1 when kbdmux isn't used. In this
case, the keyboard was correctly allocated, but the returned index was
discarded.

A new terminal_set_cursor() is added: it wraps the existing
teken_set_cursor() function.
In vtbuf_grow(), the cursor position is adjusted at the end of the
function. In vt_change_font(), we call terminal_set_cursor() just after
terminal_set_winsize_blank(), while the terminal is mute.
This fixes a bug where, after loading a kernel video driver which
increases the terminal window size, the cursor remains at its old
position, in other words, in the middle of the display content.

cxgbe(4): bump up PF4's share of some global resources.
This increases the size of the per-port RSS slice and also allows the
driver to use a larger number of tx and rx queues.
S2curity:
Update isp_tgt_map and send new arrival notification if target that departed
earlier has returned. Previously that code worked only once, confusing CTL.
Use pmc_destroy_pmc_descriptor() to actually free the pmc, which is
consistent with pmc_destroy_owner_descriptor(). Also be sure to destroy
PMCs if a process exits or execs without explicitly releasing them.
Improve transmit sending offload, TSO, algorithm in general. This
change allows all HCAs from Mellanox Technologies to function properly
when TSO is enabled. See r271946 and r272595 for more details about
this commit.

The SYSCTL data pointers can come from userspace and must not be
directly accessed. Although this will work on some platforms, it can
throw an exception if the pointer is invalid and then panic the kernel.
Add a missing SYSCTL_IN() of "SCTP_BASE_STATS" structure.

Return the actual baud rate programmed in the hardware rather than 115200.
This allows the "3wire" entry in /etc/ttys (with no speed specified) to work.
Use the FIFOs in the imx5/imx6 uart hardware instead of interrupting on
each byte sent or received.
Replace multiple nearly-identical copies of code to walk through an FDT
node's interrupts=<...> property creating resource list entries with a
single common implementation. This change makes ofw_bus_intr_to_rl() the
one true copy of that code and removes the copies of it from other places.
This also adds handling of the interrupts-extended property.
Create a mechanism for looking up a device_t associated with an ofw/fdt
xref handle, and for registering that association. Also use the same data
for faster translations between node and xref handles.
Add OF_xref_from_device() so that there's no need to have an intermediate
call to ofw_bus_get_node() to lookup info that's already in the xreflist.
When registering an association between a device and an xref phandle, create
an entry in the xref list if one doesn't already exist for the given handle.

Add support for QAC AR816x/AR817x Gigabit/Fast Ethernet controllers.
These controllers seem to have the same feature of AR813x/AR815x and
improved RSS support(4 TX queues and 8 RX queues). alc(4) supports
all hardware features except RSS. I didn't implement RX checksum
offloading for AR816x/AR817x just because I couldn't get
confirmation from the Vendor whether AR816x/AR817x corrected its
predecessor's RX checksum offloading bug on fragmented packets.
This change adds supports for the following controllers.
o AR8161 PCIe Gigabit Ethernet controller
o AR8162 PCIe Fast Ethernet controller
o AR8171 PCIe Gigabit Ethernet controller
o AR8172 PCIe Fast Ethernet controller
o Killer E2200 Gigabit Ethernet controller
Relnotes: yes
Add new quirk PCI_QUIRK_MSI_INTX_BUG to pci(4).
QAC AR816x/E2200 controller has a silicon bug that MSI interrupt
does not assert if PCIM_CMD_INTxDIS bit of command register is set.
Fix a long standing bug in MAC statistics register access. One
additional register was erroneously added in the MAC register set
such that 7 TX statistics counters were wrong.
It allows to push out some final data from the send queue to the socket
before its close. In particular, it increases chances for logout response
to be delivered to the initiator.
