+Properties for an MDIO bus multiplexer controlled by a memory-mapped device
+
+This is a special case of a MDIO bus multiplexer. A memory-mapped device,
+like an FPGA, is used to control which child bus is connected. The mdio-mux
+node must be a child of the memory-mapped device. The driver currently only
+supports devices with eight-bit registers.
+
+Required properties in addition to the generic multiplexer properties:
+
+- compatible : string, must contain "mdio-mux-mmioreg"
+
+- reg : integer, contains the offset of the register that controls the bus
+ multiplexer. The size field in the 'reg' property is the size of
+ register, and must therefore be 1.
+
+- mux-mask : integer, contains an eight-bit mask that specifies which
+ bits in the register control the actual bus multiplexer. The
+ 'reg' property of each child mdio-mux node must be constrained by
+ this mask.
+
+Example:
+
+The FPGA node defines a memory-mapped FPGA with a register space of 0x30 bytes.
+For the "EMI2" MDIO bus, register 9 (BRDCFG1) controls the mux on that bus.
+A bitmask of 0x6 means that bits 1 and 2 (bit 0 is lsb) are the bits on
+BRDCFG1 that control the actual mux.
+
+ /* The FPGA node */
+ fpga: board-control@3,0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "fsl,p5020ds-fpga", "fsl,fpga-ngpixis";
+ reg = <3 0 0x30>;
+ ranges = <0 3 0 0x30>;
+
+ mdio-mux-emi2 {
+ compatible = "mdio-mux-mmioreg", "mdio-mux";
+ mdio-parent-bus = <&xmdio0>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <9 1>; // BRDCFG1
+ mux-mask = <0x6>; // EMI2
+
+ emi2_slot1: mdio@0 { // Slot 1 XAUI (FM2)
+ reg = <0>;
+ #address-cells = <1>;
+ #size-cells = <0>;

be retransmitted. Should not be higher than 255. Default value
- is 5, which corresponds to ~180seconds.

tcp_syncookies - BOOLEAN
Only valid when the kernel was compiled with CONFIG_SYNCOOKIES
tcp_fastopen - INTEGER
Enable TCP Fast Open feature (draft-ietf-tcpm-fastopen) to send data
in the opening SYN packet. To use this feature, the client application
- must not use connect(). Instead, it should use sendmsg() or sendto()
- with MSG_FASTOPEN flag which performs a TCP handshake automatically.

- 1: Enables sending data in the opening SYN on the client
- 5: Enables sending data in the opening SYN on the client regardless
- of cookie availability.
+ must use sendmsg() or sendto() with MSG_FASTOPEN flag rather than
+ connect() to perform a TCP handshake automatically.
+
+ The values (bitmap) are
+ 1: Enables sending data in the opening SYN on the client.
+ 2: Enables TCP Fast Open on the server side, i.e., allowing data in
+ a SYN packet to be accepted and passed to the application before
+ 3-way hand shake finishes.
+ 4: Send data in the opening SYN regardless of cookie availability and
+ without a cookie option.
+ 0x100: Accept SYN data w/o validating the cookie.
+ 0x200: Accept data-in-SYN w/o any cookie option present.

Default: 0

+ * to NULL when a TFO socket no longer needs to access the request_sock.
+ * This happens only after 3WHS has been either completed or aborted (e.g.,
+ * RST is received).
+ *
+ * Before TFO, a child socket is created only after 3WHS is completed,
+ * hence it never needs to access the request_sock. things get a lot more
+ * complex with TFO. A child socket, accepted or not, has to access its
+ * request_sock for 3WHS processing, e.g., to retransmit SYN-ACK pkts,
+ * until 3WHS is either completed or aborted. Afterwards the req will stay
+ * until either the child socket is accepted, or in the rare case when the
+ * listener is closed before the child is accepted.
+ *
+ * In short, a request socket is only freed after BOTH 3WHS has completed
+ * (or aborted) and the child socket has been accepted (or listener closed).
+ * When a child socket is accepted, its corresponding req->sk is set to
+ * NULL since it's no longer needed. More importantly, "req->sk == NULL"
+ * will be used by the code below to determine if a child socket has been
+ * accepted or not, and the check is protected by the fastopenq->lock
+ * described below.
+ *
+ * Note that fastopen_rsk is only accessed from the child socket's context
+ * with its socket lock held. But a request_sock (req) can be accessed by
+ * both its child socket through fastopen_rsk, and a listener socket through
+ * icsk_accept_queue.rskq_accept_head. To protect the access a simple spin
+ * lock per listener "icsk->icsk_accept_queue.fastopenq->lock" is created.
+ * only in the rare case when both the listener and the child locks are held,
+ * e.g., in inet_csk_listen_stop() do we not need to acquire the lock.
+ * The lock also protects other fields such as fastopenq->qlen, which is
+ * decremented by this function when fastopen_rsk is no longer needed.
+ *
+ * Note that another solution was to simply use the existing socket lock
+ * from the listener. But first socket lock is difficult to use. It is not
+ * a simple spin lock - one must consider sock_owned_by_user() and arrange
+ * to use sk_add_backlog() stuff. But what really makes it infeasible is the
+ * locking hierarchy violation. E.g., inet_csk_listen_stop() may try to
+ * acquire a child's lock while holding listener's socket lock. A corner
+ * case might also exist in tcp_v4_hnd_req() that will trigger this locking
+ * order.
+ *
+ * When a TFO req is created, it needs to sock_hold its listener to prevent
+ * the latter data structure from going away.
+ *
+ * This function also sets "treq->listener" to NULL and unreference listener
+ * socket. treq->listener is used by the listener so it is protected by the
+ * fastopenq->lock in this function.

+ select IPV6_TUNNEL
+ ---help---
+ Tunneling means encapsulating data of one protocol type within
+ another protocol and sending it over a channel that understands the
+ encapsulating protocol. This particular tunneling driver implements
+ GRE (Generic Routing Encapsulation) and at this time allows
+ encapsulating of IPv4 or IPv6 over existing IPv6 infrastructure.
+ This driver is useful if the other endpoint is a Cisco router: Cisco
+ likes GRE much better than the other Linux tunneling driver ("IP
+ tunneling" above). In addition, GRE allows multicast redistribution
+ through the tunnel.
+
+ Saying M here will produce a module called ip6_gre. If unsure, say N.

- *
- * It skips all well-known exthdrs, and returns pointer to the start

- * if success, *nexthdr is updated by type/protocol of this header.
- *
- * NOTES: - it may return pointer pointing beyond end of packet,
- * if the last recognized header is truncated in the middle.
- * - if packet is truncated, so that all parsed headers are skipped,
- * it returns -1.
- * - if packet is fragmented, return pointer of the fragment header.
- * - ESP is unparsable for now and considered like
- * normal payload protocol.
