copy_file_range: Call vn_rdwr() at least once
This ensures that we invoke VOP_READ on the input file even if it's
empty, which in turn helps ensure that filesystems update the atime of
the file.

bpf: Make BPF interop consistent with if_loop
The pseudo_AF_HDRCMPLT check is already being done in if_loop and
just needed to be ported over to if_ic, if_wg, if_disc, if_gif,
if_gre, if_me, if_tuntap and ng_iface. This is needed in order to
allow these interfaces to work properly with e.g., tcpreplay.

tcp: add counter to track when SACK loss recovery uses TSO
Add a counter to track how frequently SACK has transmitted
more than one MSS using TSO. Instances when this will be
beneficial is the use of PRR, or when ACK thinning due to
GRO/LRO or ACK discards by the network are present.

tcp: filter small SACK blocks
While the SACK Scoreboard in the base stack limits
the number of holes by default to only 128 per connection
in order to prevent CPU load attacks by splitting SACKs,
filtering out SACK blocks of unusually small size can
further improve the actual processing of SACK loss recovery.

pf: always mark states as unlinked before detaching them
Users have reported crashes in pf_test_state_udp() where at least one state key
is NULL.
That suggests that pf_detach_state() ran concurrently with pf_test_state_udp().
pf_test_state_udp() holds the state lock (aka the id lock), but
pf_detach_state() does not.
The intent is that detached states are not returned by STATE_LOOKUP/
pf_find_state(), as the state's timeout is set to PFTM_UNLINKED and thus
pf_find_state() does not find the state.
There are other paths to pf_detach_state() (outside of pf_unlink_state())
though, where we did not set the timeout to PFTM_UNLINKED. Fix those, and assert
that the timeout is set correctly when we enter pf_detach_state().

carp: refactor packet tagging for ether_output()
- Separate HMAC preparation (CARP specific) from tagging.
- In unicast mode (CARP specific) don't put tag at all.
- Don't put pointer to software context into the tag. Putting just vhid,
an integer value, is a safer design.

carp: isolate VRRP from CARP
There is only one functional change here - we don't allow SIOCSVH (or
netlink request) to change sc->sc_version. I'm convinced that allowing
such a change doesn't brings any practical value, but creates enless
minefields in front of both developers and end users (sysadmins). If
you want to switch from VRRP to CARP or vice versa, you'd need to recreate
the VHID.
Oh, one tiny funtional change: carp_ioctl_set() won't modify any fields
if it returns EINVAL. Previously you could provide valid advbase with
invalid advskew - that used to modify advbase and return EINVAL.
All other changes is a sweep around not ever using CARP fields when
we are in VRRP mode and vice versa. Also adding assertions on sc_version
where necessary.
Do not send VRRP vars in CARP mode via NetLink and vice versa. However
in compat ioctl SIOCGVH for VRRP mode the CARP fields would be zeroes.

carp: support VRRPv3
Allow carp(4) to use the VRRPv3 protocol (RFC 5798). We can distinguish carp and
VRRP based on the protocol version number (carp is 2, VRRPv3 is 3), and support
both from the carp(4) code.

Version 0.17.1 speeds up "jj status" by no longer scanning through
