e1000/e1000e split in linux.
Split rxbuffer and txbuffer apart to support the new RX descriptor format
structures. Move rxbuffer manipulation to em_setup_rxdesc() to unify the
new behavior changes.
Add a RSSKEYLEN macro for help in generating the RSSKEY data structures
in the card.
Change em_receive_checksum() to process the new rxdescriptor format
status bit.

Previously nvme(4) would revert to a signle I/O queue if it could not
allocate enought interrupt vectors or NVMe submission/completion queues
to have one I/O queue per core. This patch determines how to utilize a
smaller number of available interrupt vectors, and assigns (as closely
as possible) an equal number of cores to each associated I/O queue.

Instead just use num_io_queues to make this determination.
This prepares for some future changes enabling use of multiple
queues when we do not have enough queues or MSI-X vectors
for one queue per CPU.

This significantly improves parallelism in the most common case.
The taskqueue is still used whenever BIO_ORDERED bios are in flight.
This patch is based heavily on a patch from gallatin@.

This ensures the bio flags are not read after biodone().
The ordering will still be enforced, after the bio is

Still wait until all in-flight bios (including the ordered bio)
complete before processing more bios from the queue.

rin6 was used only as sockaddr_in6 storage. Make rtalloc1_fib()
use on-stack sin6 and return rtenry directly, instead of doing
useless work with 'struct route_in6'.
Similar fix was done for passwd and group operations in r285050. When a
temporary file is created and then renamed to replace official file there
are no checks to make sure data was written to disk and if a power cycle
happens at this time, system can end up with a 0 length file

The upcoming GELI support in the loader reuses parts of this code
Some ifdefs are added, and some code is moved outside of existing ifdefs
The HMAC parts of GELI are broken out into their own file, to separate
them from the kernel crypto/openssl dependant parts that are replaced
in the boot code.
Passed the GELI regression suite (tools/regression/geom/eli)

This will ensure that the variable was not set as a make override, in
make.conf, src.conf or src-env.conf. It allows setting the value in
src-env.conf when using WITH_AUTO_OBJ since that case properly handles
changing .OBJDIR (except if MAKEOBJDIRPREFIX does not yet exist which is
being discussed to be changed).
This change allows setting a default MAKEOBJDIRPREFIX via local.sys.env.mk.

We intend to replace GNU ld with LLVM's lld, and on the path to there
we'll experiment with having lld installed or linked as /usr/bin/ld.
Thus, make ld.bfd the primary install target for GNU ld, to later
facilitate making the ld link optional.

and t_maxseg. This dualism emerged with T/TCP, but was not properly cleaned
up after T/TCP removal. After all permutations over the years the result is
that t_maxopd stores a minimum of peer offered MSS and MTU reduced by minimum
protocol header. And t_maxseg stores (t_maxopd - TCPOLEN_TSTAMP_APPA) if
timestamps are in action, or is equal to t_maxopd otherwise. That's a very
rough estimate of MSS reduced by options length. Throughout the code it
was used in places, where preciseness was not important, like cwnd or
ssthresh calculations.
With this change:
- t_maxopd goes away.
- t_maxseg now stores MSS not adjusted by options.
- new function tcp_maxseg() is provided, that calculates MSS reduced by
options length. The functions gives a better estimate, since it takes
into account SACK state as well.

indicates the 'release' target has run (in order to prevent
subsequent invocations that may clobber original build output).
As is, the 'release' target is a dummy target that does nothing
more than depend on subsequent targets. Unless 'make obj' is
invoked prior to 'make release', .OBJDIR and .CURDIR will always
be '/usr/src/release' (or wherever /usr/src is located).
When 'make release' invokes 'make real-release' (and subsequent
targets), .OBJDIR is not updated, which still leads to src/ tree
pollution.
While arguably a hack, 'make release' will invoke the original
dummy targets as originally intended, but instead of touching an
empty file (or returing @true), will call a 'release-done' target
that will trigger the behavior that was intended to prevent
a subsequent invocation.

Fix a bug in rpcbind for multihomed hosts. If the server had interfaces on
two separate subnets, and a client on the first subnet contacted rpcbind at
the address on the second subnet, rpcbind would advertise addresses on the
first subnet. This is a bug, because it should prefer to advertise the
address where it was contacted. The requested service might be firewalled
off from the address on the first subnet, for example.
usr.sbin/rpcbind/check_bound.c
If the address on which a request was received is known, pass that
to addrmerge as the clnt_uaddr parameter. That is what addrmerge's
comment indicates the parameter is supposed to mean. The previous
behavior is that clnt_uaddr would contain the address from which the
client sent the request.
usr.sbin/rpcbind/util.c
Modify addrmerge to prefer to use an IP that is equal to clnt_uaddr,
if one is found. Refactor the relevant portion of the function for
clarity, and to reduce the number of ifdefs.
