Igal Liberman 5adae51a64 fsl/fman: Add FMan MURAM support
Add Frame Manager Multi-User RAM support.
This internal FMan memory block is used by the
FMan hardware modules, the management being made
through the generic allocator.

The FMan Internal memory, for example, is used for
allocating transmit and receive FIFOs.

Pravin B Shelar 039f50629b ip_tunnel: Move stats update to iptunnel_xmit()
By moving stats update into iptunnel_xmit(), we can simplify
iptunnel_xmit() usage. With this change there is no need to
call another function (iptunnel_xmit_stats()) to update stats

Florian Westphal 271c3b9b7b tcp: honour SO_BINDTODEVICE for TW_RST case too
Hannes points out that when we generate tcp reset for timewait sockets we
pretend we found no socket and pass NULL sk to tcp_vX_send_reset().

Make it cope with inet tw sockets and then provide tw sk.

This makes RSTs appear on correct interface when SO_BINDTODEVICE is used.

Packetdrill test case:
// want default route to be used, we rely on BINDTODEVICE
`ip route del 192.0.2.0/24 via 192.168.0.2 dev tun0`

0.000 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
// test case still works due to BINDTODEVICE
0.001 setsockopt(3, SOL_SOCKET, SO_BINDTODEVICE, "tun0", 4) = 0
0.100...0.200 connect(3, ..., ...) = 0

0.100 > S 0:0(0) <mss 1460,sackOK,nop,nop>
0.200 < S. 0:0(0) ack 1 win 32792 <mss 1460,sackOK,nop,nop>

Florian Westphal e46787f0dd tcp: send_reset: test for non-NULL sk first
tcp_md5_do_lookup requires a full socket, so once we extend
_send_reset() to also accept timewait socket we would have to change

if (!sk && hash_location)

to something like

if ((!sk || !sk_fullsock(sk)) && hash_location) {
  ...
} else {
  (sk && sk_fullsock(sk)) tcp_md5_do_lookup()
}

Switch the two branches: check if we have a socket first, then
fall back to a listener lookup if we saw a md5 option (hash_location).

Lorenzo Colitti 2010b93e93 net: tcp: deal with listen sockets properly in tcp_abort.
When closing a listen socket, tcp_abort currently calls
tcp_done without clearing the request queue. If the socket has a
child socket that is established but not yet accepted, the child
socket is then left without a parent, causing a leak.

Fix this by setting the socket state to TCP_CLOSE and calling
inet_csk_listen_stop with the socket lock held, like tcp_close
does.

Tested using net_test. With this patch, calling SOCK_DESTROY on a
listen socket that has an established but not yet accepted child
socket results in the parent and the child being closed, such
that they no longer appear in sock_diag dumps.

====================
100GbE Intel Wired LAN Driver Updates 2015-12-22

This series contains updates to fm10k only.

Bruce cleans up the initialization of fm10k_workqueue at the global level,
which fixes a checkpatch.pl error.  Made several other cleanups of the
driver, like making structures that do not change constant, remove unused
code, cleanup code comments and use boolean states true/false instead of
an integer since a bool is all that is needed.

Jacob fixed the TLV format for little endian structures which are 4 byte
aligned copy, so add an additional __aligned(4) and __packed to ensure
that these structures are actually 4 byte aligned and packed correctly.
Updated the driver to use ether_addr_equal() instead of memcmp() to
compare MAC addresses.

Alex Duyck cleans up the exception handling so all of the paths result in
a similar state if we fail.  Specifically the driver will now unload the
mailbox interrupt, free the queue vectors and MSI-X, and then detach the
interface.

driver so that all of the paths should result in a similar state if we
fail.

Specifically the driver will now unload the mailbox interrupt, free the
queue vectors and MSI-X, and then detach the interface.

In addition for any of the PCIe related resets I have added a check with
the hw_ready function to just make sure the registers are in a readable
state prior to reopening the interface.

Jacob Keller 8c2a029c7e fm10k: correctly pack TLV structures and explain reasoning
The TLV format for little endian structures is actually 4 byte aligned
copy. To this end, we need to add an additional __aligned(4) marker
along with __packed to ensure that these structures are actually 4 byte
aligned and packed correctly. Use of just __packed will not work as this
will result in 1byte alignment which is incorrect. Add a comment
explaining the reasoning behind why these structures need the special
treatment.

Nicholas Mc Guire 076ef44070 ibmveth: consolidate kmalloc of array, memset 0 to kcalloc
This is an API consolidation only. The use of kmalloc + memset to 0
is equivalent to kcalloc in this case as it is allocating an array
of elements.

Arnd Bergmann 958d104e3d netcp: fix regression in receive processing
A cleanup patch I did was unfortunately wrong and introduced
multiple serious bugs in the netcp rx processing, as indicated
by these correct gcc warnings:

drivers/net/ethernet/ti/netcp_core.c:776:14: warning: 'buf_ptr' may be used uninitialized in this function [-Wuninitialized]
drivers/net/ethernet/ti/netcp_core.c:687:14: warning: 'ptr' may be used uninitialized in this function [-Wuninitialized]

I have checked the patch once more and found that a call to
get_pkt_info() accidentally got removed in netcp_free_rx_desc_chain,
and netcp_process_one_rx_packet no longer retrieved the correct
buffer length. This patch should fix all the known problems,
but I did not test on real hardware.
