This permits requests (netipsec ESP and AH protocol) to provide the
IPsec ESN (Extended Sequence Numbers) in a separate buffer.
As with separate output buffer and separate AAD buffer not all drivers
support this feature. Consumer must request use of this feature via new

Until clang 11 that was equivalent to -O2, but clang changed it to -O1 so
generated MIPS code will now be unnecessarily slow. It also removes a weird
special case from sys.mk.
This is similar to the D26471 change for debug kernels and should not change
anything since everything was previously building MIPS code at -O2 until the
clang 11 update.

These kind of drops come for free in the sense that they do not use the
filter TCAM or any other resource that wouldn't normally be used during
rx. Frames dropped by the hardware get counted in the MAC's rx stats
but are not delivered to the driver.
hw.cxgbe.attack_filter
Set to 1 to enable the "attack filter". Default is 0. The attack
filter will drop an incoming frame if any of these conditions is true:
src ip/ip6 == dst ip/ip6; tcp and src/dst ip is not unicast; src/dst ip
is loopback (127.x.y.z); src ip6 is not unicast; src/dst ip6 is loopback
(::1/128) or unspecified (::/128); tcp and src/dst ip6 is mcast
(ff00::/8).
hw.cxgbe.drop_ip_fragments
Set to 1 to drop all incoming IP fragments. Default is 0. Note that
this drops valid frames.
hw.cxgbe.drop_pkts_with_l2_errors
Set to 1 to drop incoming frames with Layer 2 length or checksum errors.
Default is 1.
hw.cxgbe.drop_pkts_with_l3_errors
Set to 1 to drop incoming frames with IP version, length, or checksum
errors. Default is 0.
hw.cxgbe.drop_pkts_with_l4_errors
Set to 1 to drop incoming frames with Layer 4 length, checksum, or other
errors. Default is 0.

For interfaces that do not support SIOCGIFMEDIA (for which there are
quite a few) the only fallback is to query the interface for
if_data->ifi_link_state. While it's possible to get at if_data for an
interface via getifaddrs(3) or sysctl, both are heavy weight mechanisms.
SIOCGIFDATA is a simple ioctl to retrieve this fast with very little
resource use in comparison. This implementation mirrors that of other
similar ioctls in FreeBSD.

Document the new powerpc64le arch's initial specifications.
Certain things are subject to change while this is experimental. The most
likely change is that long double may switch to quad, dependent on POWER8
emulation assistance for __float128 being set up in the compiler (as
POWER8 does not have IEEE-compatible 128-bit hardware float, unlike POWER9.)

This adds the getenv_bool() function, to parse a boolean value from a
kernel environment variable or tunable. This works for traditional
boolean values like "0" and "1", and also "true" and "false"
(case-insensitive). These semantics do not yet apply to sysctls declared
using SYSCTL_BOOL with CTLFLAG_TUN (they still only parse 1 and 0).
Also added are two wrapper functions, getenv_is_true() and
getenv_is_false(). These are slightly simpler for callers wishing to
perform a single check of a configuration variable.

bootonce feature is temporary, one time boot, activated by
"bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag.
By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.
By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will
be set permanently active.
bootonce dataset name is recorded in boot pool labels, bootenv area.
in case of nextboot, the nextboot_enable boolean variable is recorded in
freebsd:nvstore nvlist, also stored in boot pool label bootenv area.
On boot, the loader will process /boot/nextboot.conf if nextboot_enable
is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf
processing on next boot.
bootonce and nextboot features are usable in both UEFI and BIOS boot.
To use bootonce/nextboot features, the boot loader needs to be updated on disk;
if loader.efi is stored on ESP, then ESP needs to be updated and
for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated
(gpart or other tools).
At this time, only lua loader is updated.
