Now each branch has one and only one possible TxQ lock state.
It simplifies understanding of the code.

We can't disable it in HW, but we can ignore result.
Discard Rx descriptor checksum flags if Rx checksum offload is off.

sfxge: split sfxge_tx_qdpl_put() into *_locked() and *_unlocked()
It simplifies understanding of the sfxge_tx_packet_add() logic and
avoids passing of 'locked' to called function.

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.

Allow DSP basename cloning to be disabled or enabled at boot and
runtime. This is useful when implementing OSS sound stacks in
userspace via libcuse for example.
* 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.

Fix CARP when in use in a HyperV environment:
- Bump link state when stopping or starting the interface;
- Don't handle SIOCGIFADDR specially, similar to r277103.
This change is based on a previous revision from Andy Zhang
(Microsoft) who did the diagnostic work and many thanks to
them for their help in supporting the HyperV work.

nvme: create separate DMA tag for non-payload DMA buffers

nvme: fall back to a smaller MSI-X vector allocation if necessary
Previously, if per-CPU MSI-X vectors could not be allocated,
nvme(4) would fall back to INTx with a single I/O queue pair.
This change will still fall back to a single I/O queue pair, but
allocate MSI-X vectors instead of reverting to INTx.

For igb(4), when we are doing multiqueue, we are all setup to have full 32bit

Make sure the adapter's management queue and the event queue are
available before any uppper layer driver (TOE, iWARP, or iSCSI)
registers with the base cxgbe(4) driver.
cxgbe(4): Verify that the addresses in if_multiaddrs really are multicast
addresses. (The chip doesn't really care, it's just that it needs to be
told explicitly if unicast DMACs are checked for "hits" in the hash that
is used after the TCAM entries are all used up).
This update brings few features:
o Support for the setmaster/dropmaster ioctls. For instance, they
are used to run multiple X servers simultaneously.
o Support for minor devices. The only user-visible change is a new
entry in /dev/dri but it is useless at the moment. This is a
first step to support render nodes [1].
The main benefit is to greatly reduce the diff with Linux (at the
expense of an unreadable commit diff). Hopefully, next upgrades will be
easier.
No updates were made to the drivers, beside adapting them to API
changes.

r275358:
Start process of removing the use of the deprecated "M_FLOWID" flag
from the FreeBSD network code. The flag is still kept around in the
"sys/mbuf.h" header file, but does no longer have any users. Instead
the "m_pkthdr.rsstype" field in the mbuf structure is now used to
decide the meaning of the "m_pkthdr.flowid" field. To modify the
"m_pkthdr.rsstype" field please use the existing "M_HASHTYPE_XXX"
macros as defined in the "sys/mbuf.h" header file.
This patch introduces new behaviour in the transmit direction.
Previously network drivers checked if "M_FLOWID" was set in "m_flags"
before using the "m_pkthdr.flowid" field. This check has now now been
replaced by checking if "M_HASHTYPE_GET(m)" is different from
"M_HASHTYPE_NONE". In the future more hashtypes will be added, for
example hashtypes for hardware dedicated flows.
"M_HASHTYPE_OPAQUE" indicates that the "m_pkthdr.flowid" value is
valid and has no particular type. This change removes the need for an
"if" statement in TCP transmit code checking for the presence of a
valid flowid value. The "if" statement mentioned above is now a direct
variable assignment which is then later checked by the respective
network drivers like before.
r275483:
Remove M_FLOWID from SCTP code.
r276982:
Remove no longer used "M_FLOWID" flag from mbuf.h and update the netisr
manpage.
Note: The FreeBSD version has been bumped.

Move the message complaining about failed system resource allocations
under bootverbose. Every example I've seen to date has been due to
an ACPI system resource device reserving a range that overlaps with
system memory (which ram0 attempts to reserve) or a local or I/O APIC
(which apic0 attempts to reserve). These are always harmless but look
scary to users.
