drivers/net/can/mscan/mpc5xxx_can.c: Add of_node_put to avoid memory leak
Add a call to of_node_put in the error handling code following a call to
of_find_matching_node.
This patch also moves the existing call to of_node_put after the call to
iounmap in the error handling code, to make it possible to jump to
of_node_put without doing iounmap. These appear to be disjoint operations,
so the ordering doesn't matter.
This patch furthermore changes the -ENODEV result in the error handling

TCP: update initial windows according to RFC 5681
This updates the use of larger initial windows, as originally specified in

The changes made in RFC 5681 are:
a) the setting now is more clearly specified in units of segments (as the
comments by John Heffner emphasized, this was not very clear in RFC 3390);
b) for connections with 1095 < SMSS <= 2190 there is now a change:
- RFC 3390 says that IW <= 4380,
- RFC 5681 says that IW = 3 * SMSS <= 6570.
Since RFC 3390 is older and "only" proposed standard, whereas the newer RFC 5681
is already draft standard, it seems preferable to use the newer IW variant.

This tunable does not affect the initial RTO value of 2 seconds specified in

tcp: Add TCP_USER_TIMEOUT socket option.
This patch provides a "user timeout" support as described in RFC793. The
socket option is also needed for the the local half of RFC5482 "TCP User
Timeout Option".
TCP_USER_TIMEOUT is a TCP level socket option that takes an unsigned int,
when > 0, to specify the maximum amount of time in ms that transmitted
data may remain unacknowledged before TCP will forcefully close the
corresponding connection and return ETIMEDOUT to the application. If
0 is given, TCP will continue to use the system default.
Increasing the user timeouts allows a TCP connection to survive extended
periods without end-to-end connectivity. Decreasing the user timeouts
allows applications to "fail fast" if so desired. Otherwise it may take
upto 20 minutes with the current system defaults in a normal WAN
environment.
The socket option can be made during any state of a TCP connection, but
is only effective during the synchronized states of a connection
(ESTABLISHED, FIN-WAIT-1, FIN-WAIT-2, CLOSE-WAIT, CLOSING, or LAST-ACK).
Moreover, when used with the TCP keepalive (SO_KEEPALIVE) option,
TCP_USER_TIMEOUT will overtake keepalive to determine when to close a
connection due to keepalive failure.
The option does not change in anyway when TCP retransmits a packet, nor
when a keepalive probe will be sent.
This option, like many others, will be inherited by an acceptor from its
listener.

ip_vs_add_service() and ip_vs_new_dest(), as we hold a mutex and are
allowed to sleep in this context.

bna: Fixed build break for allyesconfig
This is the patch to fix the build break caused by multiple
definitions of symbols between Brocade's FC/FCOE driver(BFA)
and 10G Networking Driver(BNA).
Changes are:
1. locally used functions are made static
2. unused functions are removed
3. using unique namespaces for the function names that must be
globally visible

be2net: fix to dynamically generate MAC Address for VFs
The BE ASIC/firmware doesnot reserve and assign MAC address for VFs.
This results in the VF interfaces being created with MAC Address 0.
The code change proposed takes the MAC address of PF to generate a seed.
MAC Address for VFs are assigned incrementally starting from the seed.
These addresses are programmed in the ASIC by the PF and the VF driver
queries for the MAC address during its probe.

qlge: Fix a deadlock when the interface is going down
Currently qlge can deadlock when the interface is going
down, and the mpi_port_cfg_work() is executing on another
processor. It happens because unregister_netdev() holds
the rtnl lock, and the mpi_port_cfg_work() also request
this lock.
Since unregiter_netdev() may wait mpi_port_cfg_work(), who
also request the holding lock, it can cause an deadlock,
displaying the following error:
