- Fix inittodr() and resettodr(). These are broken by rev.1.154.
If these drivers are setting M_VLANTAG because they are stripping the
layer 2 802.1Q headers, then they need to be re-inserting them so any
bpf(4) peers can properly decode them.
It should be noted that this is compiled tested only.

to embed a timestamp (struct timeval) in outgoing packets. The message
specifies the offset at which the timestamp should be inserted.
NG_SOURCE(4) gives an example usage that queues an ICMP packet. Using that
example, the following command will insert a timestamp in the ICMP's data
payload:
ngctl msg src0: settimestamp '{ offset=0x2a flags=1 }'

this patch the code behaves according to the comment on the line above.
Without this patch, a socket could cause SIGPIPE to be delivered to its
process, once with SO_NOSIGPIPE set, and twice without.
With this patch, the kernel now passes the sigpipe regression test.

An mbuf packet chain with the M_PROMISC flag set contains a unicast packet
received by the link layer, which does not correspond to any configured
link layer address in the local system.
It is copied when copying m_pkthdr. It is not cleared when crossing layers.
As such, it is defined to have a flag value which is outside of the
M_PROTO* range, like M_VLANTAG has.

been set at the socket layer, in our somewhat convoluted IPv4 source
selection logic in ip_output().
IP_ONESBCAST is actually a special case of SO_DONTROUTE, as 255.255.255.255
must always be delivered on a local link with a TTL of 1.
If IP_ONESBCAST has been set at the socket layer, also perform destination
interface lookup for point-to-point interfaces based on the destination
address of the link; previously it was not possible to use the option with
such interfaces; also, the destination/broadcast address fields map to the
same field within struct ifnet, which doesn't help matters.
One more valid fix going forward for these issues is to treat 255.255.255.255
as a destination in its own right in the forwarding trie. Other
implementations do this. It fits with the use of multiple paths, though
it then becomes necessary to specify interface preference.
This hack will eventually go away when that comes to pass.

adds to the stack evidently has a measurable performance impact on certain workloads.

them out and avoiding the unpcb lock acquire in the common case. This
avoids deadlocks which manifested with X11, and should also marginally
further improve performance.

Add macro EVL_APPLY_VLID() which may be used to apply an 802.1q VLAN ID
to the M_VLANTAG field in an mbuf packet header non-destructively.
This will be used by net80211 to begin with.
Add macro EVL_APPLY_PRI() which may be used to apply an 802.1p priority
class to the M_VLANTAG field in an mbuf packet header non-destructively.
Add other macros for manipulating tags and the CFI bit.

to a READ_CAPACITY request rather than the maximum sector (off by one
problem). This causes a huge cascade of errors as the geom tasting
code tries to read the last sector (which isn't really there in the
face of this error). automated tools that manipulate disk labels and
such also have issues.
Create a new quirk READ_CAPACITY_OFFBY1 and add a quirk for the
SanDISK ImageMate that I have that suffers from this problem (the
SDDR-31). It intercepts the READ_CAPACITY response and adjusts it
from number of sectors to max sector for devices with this quirk.
Reading the Linux source suggests that there are a host of
other devices with this issue, including iPods and some popular
cameras. I've not added quirks for them, since I don't have the
devices in front of me to test.
