a1736be349 Improve camcontrol(8) handling of drive defect data.
This includes a new summary mode (-s) for camcontrol defects that
quickly tells the user the most important thing: how many defects
are in the requested list.  The actual location of the defects is
less important.

Modern drives frequently have more than the 8191 defects that can
be reported by the READ DEFECT DATA (10) command.  If they don't
have that many grown defects, they certainly have more than 8191
defects in the primary (i.e. factory) defect list.

The READ DEFECT DATA (12) command allows for longer parameter
lists, as well as indexing into the list of defects, and so allows
reporting many more defects.

This has been tested with HGST drives and Seagate drives, but
does not fully work with Seagate drives.  Once I have a Seagate
spec I may be able to determine whether it is possible to make it
work with Seagate drives.

scsi_da.h:	Add a definition for the new long block defect
		format.

		Add bit and mask definitions for the new extended
		physical sector and bytes from index defect
		formats.

		Add a prototype for the new scsi_read_defects() CDB
		building function.

scsi_da.c:	Add a new scsi_read_defects() CDB building function.
		camcontrol(8) was previously composing CDBs manually.
		This is long overdue.

camcontrol.c:	Revamp the camcontrol defects subcommand.  We now
		go through multiple stages in trying to get defect
		data off the drive while avoiding various drive
		firmware quirks.

		We start off by requesting the defect header with
		the 10 byte command.  If we're in summary mode (-s)
		and the drive reports fewer defects than can be
		represented in the 10 byte header, we're done.
		Otherwise, we know that we need to issue the
		12 byte command if the drive reports the maximum
		number of defects.

		If we're in summary mode, we're done if we get a
		good response back when asking for the 12 byte header.

		If the user has asked for the full list, then we
		use the address descriptor index field in the 12
		byte CDB to step through the list in 64K chunks.
		64K is small enough to work with most any ancient
		or modern SCSI controller.

		Add support for printing the new long block defect
		format, as well as the extended physical sector and
		bytes from index formats.  I don't have any drives
		that support the new formats.

		Add a hexadecimal output format that can be turned
		on with -X.

		Add a quiet mode (-q) that can be turned on with
		the summary mode (-s) to just print out a number.

		Revamp the error detection and recovery code for
		the defects command to work with HGST drives.

		Call the new scsi_read_defects() CDB building
		function instead of rolling the CDB ourselves.

		Pay attention to the residual from the defect list
		request when printing it out, so we don't run off
		the end of the list.

		Use the new scsi_nv library routines to convert
		from strings to numbers and back.

camcontrol.8:	Document the new defect formats (longblock, extbfi,
		extphys) and command line options (-q, -s, -S and
		-X) for the defects subcommand.

		Explain a little more about what drives generally
		do and don't support.

User has to manually update all routes.
ifconfig em0 mtu 9000->1500 -> all routes traversing em0 do not change MTU.
However, if ip[6]_output finds route with rt_mtu > interface mtu, rt_mtu
gets updated.

New behavior:
ifconfig em0 mtu 1500->9000 -> all interface routes in all fibs gets updated
with new MTU unless RTF_FIXEDMTU flag set on them.
ifconfig em0 mtu 9000->1500 -> all routes in all fibs gets updated with new
MTU unless RTF_FIXEDMTU flag set on them AND rt_mtu is less than ifp mtu.

route add ... -mtu XXX automatically sets RTF_FIXEDMTU flag.
route change .. -mtu 0 automatically removes RTF_FIXEDMTU flag.

670e8b3b8c Kill custom in_matroute() radix mathing function removing one rte mutex lock.
Initially in_matrote() in_clsroute() in their current state was introduced by
r4105 20 years ago. Instead of deleting inactive routes immediately, we kept them
in route table, setting RTPRF_OURS flag and some expire time. After that, either
GC came or RTPRF_OURS got removed on first-packet. It was a good solution
in that days (and probably another decade after that) to keep TCP metrics.
However, after moving metrics to TCP hostcache in r122922, most of in_rmx
functionality became unused. It might had been used for flushing icmp-originated
routes before rte mutexes/refcounting, but I'm not sure about that.

So it looks like this is nearly impossible to make GC do its work nowadays:

in_rtkill() ignores non-RTPRF_OURS routes.
route can only become RTPRF_OURS after dropping last reference via rtfree()
which calls in_clsroute(), which, it turn, ignores UP and non-RTF_DYNAMIC routes.

Dynamic routes can still be installed via received redirect, but they
have default lifetime (no specific rt_expire) and no one has another trie walker
to call RTFREE() on them.

So, the changelist:
* remove custom rnh_match / rnh_close matching function.
* remove all GC functions
* partially revert r256695 (proto3 is no more used inside kernel,
  it is not possible to use rt_expire from user point of view, proto3 support
  is not complete)
* Finish r241884 (similar to this commit) and remove remaining IPv6 parts

f325335caf Overhaul if_gre(4).
Split it into two modules: if_gre(4) for GRE encapsulation and
if_me(4) for minimal encapsulation within IP.

gre(4) changes:
* convert to if_transmit;
* rework locking: protect access to softc with rmlock,
  protect from concurrent ioctls with sx lock;
* correct interface accounting for outgoing datagramms (count only payload size);
* implement generic support for using IPv6 as delivery header;
* make implementation conform to the RFC 2784 and partially to RFC 2890;
* add support for GRE checksums - calculate for outgoing datagramms and check
  for inconming datagramms;
* add support for sending sequence number in GRE header;
* remove support of cached routes. This fixes problem, when gre(4) doesn't
  work at system startup. But this also removes support for having tunnels with
  the same addresses for inner and outer header.
* deprecate support for various GREXXX ioctls, that doesn't used in FreeBSD.
  Use our standard ioctls for tunnels.

me(4):
* implementation conform to RFC 2004;
* use if_transmit;
* use the same locking model as gre(4);

db0b8e10a7 Make UEFI booting of 4Kn disks work:
-	convert boot1.efi to corrrectly calculate the lba for what the
	media reports and convert the size based on what FreeBSD uses.
	The existing code would use the 512 byte lba and convert the
	size using 4K byte size.
      -	make fsck_msdosfs read the boot block as 4K so the read doesn't
	fail on a 4Kn drive since FreeBSD will error out parition reads
	of a block.  Make the bpbBytesPerSec check a multiple of 512 since
	it can be 512 or 4K depending on the disk.  This allows fsck to
	pass checking the EFI partition on a 4Kn disk.

To create the EFI file system I used:
	newfs_msdos -F 32 -S 4096 -c 1 -m 0xf8 <partition>
This works for booting 512 and 4Kn disks.

Caveat is that loader.efi cannot read the 4Kn EFI partition.  This isn't
critical right now since boot1.efi will read loader.efi from the ufs
partition.  It looks like loader.efi can be fixed via making some of the
512 bytes reads more flexible.  loader.efi doesn't have trouble reading
the ufs partition.  This is probably a simple fix.

I now have FreeBSD installed on a system with 4Kn drives and tested the
same code works on 512.

007054f070 Add vxlan interface
vxlan creates a virtual LAN by encapsulating the inner Ethernet frame in
a UDP packet. This implementation is based on RFC7348.

Currently, the IPv6 support is not fully compliant with the specification:
we should be able to receive UPDv6 packets with a zero checksum, but we
need to support RFC6935 first. Patches for this should come soon.

Encapsulation protocols such as vxlan emphasize the need for the FreeBSD
network stack to support batching, GRO, and GSO. Each frame has to make
two trips through the network stack, and each frame will be at most MTU
sized. Performance suffers accordingly.

Some latest generation NICs have begun to support vxlan HW offloads that
we should also take advantage of. VIMAGE support should also be added soon.
