Fix the spelling of IEEE80211_HE_PHY_CAP9_NOMINAL_PKT_PADDING_*
(was "NOMIMAL"). The original version came from iwlwifi
in iwlwifi-next. Other drivers (from wireless-testing) already
use the correct spelling and need this change in LinuxKPI.

When TCP_MD5SIG is set on a socket, all packets are dropped that don't
contain an MD5 signature. Relax this behavior to accept a non-signed
packet when a security association doesn't exist with the peer.
This is useful when a listen socket set with TCP_MD5SIG wants to handle
connections protected with and without MD5 signatures.

Return ENOENT from tcp_ipsec_input() when a security association is not
found. This allows callers of TCP_MD5_INPUT() to differentiate between a
security association not found and receiving a bad signature.
Also return ENOENT from tcp_ipsec_output() for consistency.

We never initialized hw->conf.flags for IEEE80211_CONF_IDLE but
on set_channel we would clear it and announce a change.
This lead to a problem that drivers may do some work every time
which was not needed and may lead to unexpected behaviour (for no
better driver code).
Properly initialize conf.flags with IEEE80211_CONF_IDLE.
Factor out the toggling into a function and clear IDLE while
sw scanning and when associated and set again when scan ends
or we are bouncing out of assoc.

libsoft was a transition from the FreeBSD/armv6 10 (and earlier) with
'softfp' ABI (that is, hardware float, but passed as integer registers)
to the 'hardfp' ABI that was in FreeBSD/armv[67] in FreeBSD 11 and
newer. It's been off by default since it was created.
This was mostly used by people that wanted to do a source upgrade of
their system from FreeBSD 10 to 11 or from 11-current before the cutover
to 11-current after. This should not be confused with the full software
floating point implementation (that doesn't use the hardware floating
point instructions at all) that is used out of tree by at least one
company selling armv7 gear that has no FPU.
There's no longer a need for the transition, so retire it like should
likely have happened sometime before FreeBSD 12 was released 3 years
ago.

Previously algorithms such as AES-CBC would provide an algorithm
without a key size for the smallest key size and additional algorithms
with an explicit key size, e.g. "aes-cbc" (128 bits), "aes-cbc192",
and "aes-cbc256".
Instead, always make the key size name explicit and reuse the
"generic" name to request running tests against all of the key sizes.
For example, for AES-CBC this means "aes-cbc128" is now the name of
the variant with a 128-bit key and "aes-cbc" runs tests of AES-CBC
with all three key sizes.
This makes it easier to run tests on all combinations of ciphers like
AES-GCM or AES-CCM with -z in a single invocation.

reverting commit 867c27c23a5c, which changed the NFS
client to use direct RPCs to the server for
IO_APPEND writes. He also spotted that the
code only invalidated buffer cache buffers
when they were marked NMODIFIED (had been
written into).
This patch modifies the NFS VOP_WRITE() to
always invalidate the buffer cache buffers
and pages for the file when IO_APPEND is
specified. It also includes some cleanup

In 4f6c66cc9c75c8, ifa_ifwithnet() was changed to no longer
ifa_ref() the returned ifaddr, and instead the caller was required
to stay in the net_epoch for as long as they wanted the ifaddr
to remain valid. However, this missed the case where an AF_LINK
lookup would call ifaddr_byindex(), which still does ifa_ref()
the ifaddr. This would cause a refcount leak.
Fix this by inlining the relevant parts of ifaddr_byindex() here,
with the ifa_ref() call removed. This also avoids an unnecessary
entry and exit from the net_epoch for this case.
I've audited all in-tree consumers of ifa_ifwithnet() that could
possibly perform an AF_LINK lookup and confirmed that none of them
will expect the ifaddr to have a reference that they need to
release.
