sfxge: fix overflow queue freeze
If TxQ lock is obtained, deferred packet list shold be serviced even if
the packet addition fails because of overflow.
Without the patch freeze happens if:
- queue is not blocked (i.e. completion does not trigger unblock and service)
- put-list overflow (1024 entries)
- sfxge_tx_packet_add() acquires TxQ lock just as it is released it in
sfxge_tx_qdpl_service() on the second CPU but before pending check
- sfxge_tx_packet_add() swizzles put-list to get-list, fails because of
non-tcp get-list overflow and returns without packet list service
- sfxge_tx_qdpl_service() on the second CPU checks that there are no
pending packets in the put-list and returns
Other possible solution is to guaranee that maximum length of the put-list
is less than maximum length of any get-list.

sfxge: avoid usage of ifm_data
The driver uses ifm_data to save capabilities mask calculated during
initialization when supported phy modes are discovered.
The patch simply calculates it when either media or options are changed.

sfxge: add local variable with changed capabilities mask
It is required for the next patch which adds dependency of TSO
capabilities from Tx checksum offloads.

sfxge: split sfxge_tx_qdpl_put() into *_locked() and *_unlocked()

sfxge: do not change CSUM_TSO when IFCAP_TSOx is changed
It is simply not required since the kernel checks corresponding
IFCAP_TSOx capability and CSUM_TSO in hw-assisted offloads.
Note that CSUM_TSO is two bits (CSUM_IP_TSO|CSUM_IP6_TSO) and both bits
are set in IPv4 and IPv6 mbufs.

m_dup() is supposed to give a writable copy of an mbuf chain. It uses
m_dup_pkthdr(), that uses M_COPYFLAGS mask to copy m_flags field.
If original mbuf chain has M_RDONLY flag, its copy also will have it.
Reset this flag explicitly.
Allow DSP basename cloning to be disabled or enabled at boot and
runtime. This is useful when implementing OSS sound stacks in

* Prevent switching to NULL or own window in the "vt_proc_window_switch"
function. This fixes an issue where X11 keyboard input can appear
stuck. The cause of the problem is a duplicate TTY device window
switch IOCTL during boot, which leaves the "vt_switch_timer" running,
because the current window is already selected. While at it factor out
some NULL checks.
* The "SYSCTL_INT()" default value is only used for read only SYSCTLs
and is not applicable unless the integer pointer is NULL. Set it to
zero to avoid confusion. While at it remove extra semicolon at the end
of the "VT_SYSCTL_INT()" macro.
* Ensure the result from signed subtraction under modulus does not
become negative.

Apply proper locking when iterating the multicast addresses and add a

Implement a simple OID number garbage collector. Given the increasing
number of dynamically created and destroyed SYSCTLs during runtime it
is very likely that the current new OID number limit of 0x7fffffff can
be reached. Especially if dynamic OID creation and destruction results
from automatic tests. Additional changes:
- Optimize the typical use case by decrementing the next automatic OID
sequence number instead of incrementing it. This saves searching time
when inserting new OIDs into a fresh parent OID node.
- Add simple check for duplicate non-automatic OID numbers.
r282898: Correct UTF-8 encoding in Británico

The menu entry "Danish ISO-8859-1 (macbook)" was first added to the

r256367 incorrectly tagged with "da". It is a Danish keyboard map, but
the description is in English and therefore must be "en".

Merge ^/projects/release-arm-redux into ^/head.
Of note:
- This commit adds native FreeBSD/arm release build support without
requiring out-of-tree utilities.
- Part of this merge removes the WANDBOARD-{SOLO,DUAL,QUAD} kernel
configuration files, for which the IMX6 kernel configuration file
should be used instead.
- The resulting images have a 'freebsd' user (password 'freebsd'),
to allow ssh(1) access when console access is not available (VGA
or serial). The default 'root' user password is set to 'root'.
- The /etc/ttys file for arm images now enable both ttyv0 and ttyu0
by default.
Note: The RPI2 kernel configuration does not yet exist in stable/10,
however the merge conflicts needed to be properly resolved.
Additionally, SRCBRANCH has been set to base/stable/10 in the updated
arm configuration files as part of this commit.

libgomp: Update to version 4.3.5.
bring initial BSD support from upstream.
This was not meant to be MFC'd at first but the original OMP support
for FreeBSD was in very poor shape. The effect of this change should
be minimal as all ports are already using the version of libgomp that
comes with the gcc ports. The local libgomp is planned to be disabled
for platforms that are not using older gcc by default so this version
of libgomp will not be shipped in tier-1 platform releases.
