To recover from this mode, one needs to flash a valid NVM image to the

+Networking over Thunderbolt cable
+---------------------------------
+Thunderbolt technology allows software communication across two hosts
+connected by a Thunderbolt cable.
+
+It is possible to tunnel any kind of traffic over Thunderbolt link but
+currently we only support Apple ThunderboltIP protocol.
+
+If the other host is running Windows or macOS only thing you need to
+do is to connect Thunderbolt cable between the two hosts, the
+``thunderbolt-net`` is loaded automatically. If the other host is also
+Linux you should load ``thunderbolt-net`` manually on one host (it does
+not matter which one)::
+
+ # modprobe thunderbolt-net
+
+This triggers module load on the other host automatically. If the driver
+is built-in to the kernel image, there is no need to do anything.
+
+The driver will create one virtual ethernet interface per Thunderbolt
+port which are named like ``thunderbolt0`` and so on. From this point
+you can either use standard userspace tools like ``ifconfig`` to
+configure the interface or let your GUI to handle it automatically.

Statically compiled regulatory database
---------------------------------------
-In most situations the userland solution using CRDA as described
-above is the preferred solution. However in some cases a set of
-rules built into the kernel itself may be desirable. To account
-for this situation, a configuration option has been provided
-(i.e. CONFIG_CFG80211_INTERNAL_REGDB). With this option enabled,
-the wireless database information contained in net/wireless/db.txt is
-used to generate a data structure encoded in net/wireless/regdb.c.
-That option also enables code in net/wireless/reg.c which queries
-the data in regdb.c as an alternative to using CRDA.

-The file net/wireless/db.txt should be kept up-to-date with the db.txt
-file available in the git repository here:
-
- git://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git
-
-Again, most users in most situations should be using the CRDA package
-provided with their distribution, and in most other situations users
-should be building and using CRDA on their own rather than using
-this option. If you are not absolutely sure that you should be using
-CONFIG_CFG80211_INTERNAL_REGDB then _DO_NOT_USE_IT_.
+When a database should be fixed into the kernel, it can be provided as a
+firmware file at build time that is then linked into the kernel.

+MAP COMMANDS
+=============
+
+| **bpftool** map show [*MAP*]
+| **bpftool** map dump *MAP*
+| **bpftool** map update *MAP* key *BYTES* value *VALUE* [*UPDATE_FLAGS*]
+| **bpftool** map lookup *MAP* key *BYTES*

+| **bpftool** map help
+|
+| *MAP* := { id MAP_ID | pinned FILE }
+| *VALUE* := { BYTES | MAP | PROGRAM }
+| *UPDATE_FLAGS* := { any | exist | noexist }
+
+DESCRIPTION
+===========
+ **bpftool map show** [*MAP*]
+ Show information about loaded maps. If *MAP* is specified
+ show information only about given map, otherwise list all
+ maps currently loaded on the system.
+
+ Output will start with map ID followed by map type and
+ zero or more named attributes (depending on kernel version).
+
+ **bpftool map dump** *MAP*
+ Dump all entries in a given *MAP*.
+
+ **bpftool map update** *MAP* **key** *BYTES* **value** *VALUE* [*UPDATE_FLAGS*]
+ Update map entry for a given *KEY*.
+
+ *UPDATE_FLAGS* can be one of: **any** update existing entry
+ or add if doesn't exit; **exist** update only if entry already
+ exists; **noexist** update only if entry doesn't exist.
+
+ **bpftool map lookup** *MAP* **key** *BYTES*
+ Lookup **key** in the map.
+
+ **bpftool map getnext** *MAP* [**key** *BYTES*]
+ Get next key. If *key* is not specified, get first key.
+
+ **bpftool map delete** *MAP* **key** *BYTES*
+ Remove entry from the map.
+
+ **bpftool map pin** *MAP* *FILE*
+ Pin map *MAP* as *FILE*.
+
+ Note: *FILE* must be located in *bpffs* mount.
+
+ **bpftool map help**
+ Print short help message.

If it's a GCC-compiled .c file, the error may be because the function
uses an inline asm() statement which has a "call" instruction. An
asm() statement with a call instruction must declare the use of the
- stack pointer in its output operand. For example, on x86_64:
+ stack pointer in its output operand. On x86_64, this means adding
+ the ASM_CALL_CONSTRAINT as an output constraint:
- register void *__sp asm("rsp");
- asm volatile("call func" : "+r" (__sp));
+ asm volatile("call func" : ASM_CALL_CONSTRAINT);
Otherwise the stack frame may not get created before the call.

+AF_VSOCK test suite
+-------------------
+These tests exercise net/vmw_vsock/ host<->guest sockets for VMware, KVM, and
+Hyper-V.
+
+The following tests are available:
+
+ * vsock_diag_test - vsock_diag.ko module for listing open sockets
+
+The following prerequisite steps are not automated and must be performed prior
+to running tests:
+
+1. Build the kernel and these tests.
+2. Install the kernel and tests on the host.
+3. Install the kernel and tests inside the guest.
+4. Boot the guest and ensure that the AF_VSOCK transport is enabled.
+
+Invoke test binaries in both directions as follows:
+
+ # host=server, guest=client
+ (host)# $TEST_BINARY --mode=server \
+ --control-port=1234 \
+ --peer-cid=3
+ (guest)# $TEST_BINARY --mode=client \
+ --control-host=$HOST_IP \
+ --control-port=1234 \
+ --peer-cid=2
+
+ # host=client, guest=server
+ (guest)# $TEST_BINARY --mode=server \
+ --control-port=1234 \
+ --peer-cid=2
+ (host)# $TEST_BINARY --mode=client \
+ --control-port=$GUEST_IP \
