PCIe allows for MSI-X BAR to be either dedicated, or MSI-X Table may
be co-located in some functional BAR. In the later case xhci(4) is
unable to allocate active resource for the table because BAR is
already activated.
Handle it by checking for this special case, and not try to alloc
resource if MSI-X BAR is IO.

The previous scheme for calculating the total size was doing sizeof
on the struct and then adding the wanted space for the buffer.
nc_name is at offset 58 while sizeof(struct namecache) is 64.
With CACHE_PATH_CUTOFF of 39 bytes and 1 byte of padding we were
allocating 104 bytes for the entry and never accounting for the 6
byte padding, wasting that space.
It no longer protects any of tested fields, keeping all the checks racy.
While here make vtryrecycle drop the vnode on its own. Avoids an additional
lock trip.
The NTB hardware starting with Skylake has some changes to the register
map and the doorbell interface. Add a new NTB_XEON_GEN3 device type and
use it to conditionalize driver logic that differs from the existing

In certain edge cases, the NIC might have only received a partial TLS
record which it needs to return to the driver. For example, if the
local socket was closed while data was still in flight, a partial TLS
record might be pending when the connection is closed. Receiving a
RST in the middle of a TLS record is another example. When this
happens, the firmware returns the the partial TLS record as plain TCP
data via CPL_RX_DATA. Handle these requests by returning an error to
OpenSSL (via so_error for KTLS or via an error TLS record header for
the older Chelsio OpenSSL interface).

mkdir -p /foo/bar/baz will mkdir each path component and ignore EEXIST.
The NOCACHE lookup will make the namecache unnecessarily evict the existing entry,
and then fallback to the fs lookup routine eventually leading namei to return an
error as the directory is already there.
For invocations like mkdir -p /usr/obj/usr/src/sys/GENERIC/modules this triggers
fallbacks to the slowpath for concurrently executing lookups.

the failover protocol is supported due to limitations in the IPoIB
architecture. Refer to the lagg(4) manual page for how to configure
and use this new feature. A new network interface type,
IFT_INFINIBANDLAG, has been added, similar to the existing
IFT_IEEE8023ADLAG .
ifconfig(8) has been updated to accept a new laggtype argument when
creating lagg(4) network interfaces. This new argument is used to
distinguish between ethernet and infiniband type of lagg(4) network
interface. The laggtype argument is optional and defaults to
ethernet. The lagg(4) command line syntax is backwards compatible.

Use ELR register value instead of LR for PMC_TRAPFRAME_TO_PC macro since
it's the former that indicates PC if the interrupted execution thread.
This fixes a bug where pmcstat lost the leaf function of the call chain
and started with the second function in the chain.
Although this change is an improvement over the previous logic there is still
posibility for incomplete data: if the leaf function does not have stack
variables and does not call any other functions compiler would not generate
a stack frame for it and the FP value would point to the caller's frame, so
instead of the actual "caller1 -> caller2 -> leaf" chain only
"caller1 -> leaf" would be captured.

802.1ad interfaces are created with ifconfig using the "vlanproto" parameter.
Eg., the following creates a 802.1Q VLAN (id #42) over a 802.1ad S-VLAN
(id #5) over a physical Ethernet interface (em0).
ifconfig vlan5 create vlandev em0 vlan 5 vlanproto 802.1ad up
ifconfig vlan42 create vlandev vlan5 vlan 42 inet 10.5.42.1/24
VLAN_MTU, VLAN_HWCSUM and VLAN_TSO capabilities should be properly
supported. VLAN_HWTAGGING is only partially supported, as there is
currently no IFCAP_VLAN_* denoting the possibility to set the VLAN
EtherType to anything else than 0x8100 (802.1ad uses 0x88A8).

Instead, add arguments to vmapbuf. Since this argument is
always a pointer use a type of void * and cast to vm_offset_t in
vmapbuf. (In CheriBSD we've altered vm_fault_quick_hold_pages to
take a pointer and check its bounds.)
In no other situtation does b_data contain a user pointer and vmapbuf
replaces b_data with the actual mapping.

Improve the code reconstructing en_tw in struct fpreg32 from FXSAVE
results so that all register states are indicated correctly. The
previous code unconditionally mapped non-empty register state to
'normalized value' constant. The new code explicitly distinguishes
the 'zero value' and 'special value' constants as well. This improves
consistency between real FSAVE and translation from FXSAVE, and
ensures that tests using PT_GETFPREGS can rely on a single correct
value independently of the underlying implementation.
