Michal Simek cb59c87dbc net: ethernet: xilinx: Do not use NO_IRQ in axienet
This driver is used on Microblaze and will be used
on Arm Zynq.
Microblaze doesn't define NO_IRQ and no IRQ is 0.
Arm still uses NO_IRQ as -1 and there is no option
to connect IRQ to irq 0.

That's why <= 0 is only one option how to find out
undefined IRQ.

Barak Witkowski 1ef1d45a9e bnx2x: Allow management traffic after boot from SAN
As part of the previous driver unload flow, whenever bnx2x is
loaded after the UNDI driver it closes all Rx traffic.
However, this leads to management traffic also being stopped until
the network interface associated with one of its functions gets loaded.

To remedy this, management traffic is re-opened once the 'cleaning'
after the previous driver ends.

Yuval Mintz 4864a16ae6 bnx2x: Fix fastpath structures when memory allocation fails
When allocating Tx queues, if for some reason
(e.g., lack of memory) allocation fails, driver will incorrectly
calculate the pointers of the various queues.

This patch repositions all pointers in such a case to point at
sequential structures in memory, allowing the bnx2x macros to
be used correctly when accessing them.

Lars-Peter Clausen ec82f94c7c bfin_mac: Restore hardware time-stamping dependency on BF518
Commit 70ac618c07 ("ptp: fixup Kconfig for two PHC drivers.") removed all
dependencies for the blackfin hardware time-stamping Kconfig entry. Hardware
time-stamping is only available on BF518 though. Since the Kconfig entry is
'default y', just updateing your kernel source and running `make defconfig` will
result in the the following build errors:

	drivers/net/ethernet/adi/bfin_mac.c:694: error: implicit declaration of function ‘bfin_read_EMAC_PTP_CTL’
	drivers/net/ethernet/adi/bfin_mac.c:702: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FV3’
	drivers/net/ethernet/adi/bfin_mac.c:712: error: implicit declaration of function ‘bfin_write_EMAC_PTP_CTL’
	drivers/net/ethernet/adi/bfin_mac.c:717: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FOFF’
	...

This patch adds back the dependency on BF518, and since it does not make sense
to expose this config option when the blackfin MAC driver is not enabled also
restore the dependency on BFIN_MAC.

Michael S. Tsirkin 9d43a18c6e tun: avoid owner checks on IFF_ATTACH_QUEUE
At the moment, we check owner when we enable queue in tun.
This seems redundant and will break some valid uses
where fd is passed around: I think TUNSETOWNER is there
to prevent others from attaching to a persistent device not
owned by them. Here the fd is already attached,
enabling/disabling queue is more like read/write.

Stefan Hajnoczi 6e331f4c83 tuntap: refuse to re-attach to different tun_struct
Multiqueue tun devices support detaching a tun_file from its tun_struct
and re-attaching at a later point in time.  This allows users to disable
a specific queue temporarily.

ioctl(TUNSETIFF) allows the user to specify the network interface to
attach by name.  This means the user can attempt to attach to interface
"B" after detaching from interface "A".

The driver is not designed to support this so check we are re-attaching
to the right tun_struct.  Failure to do so may lead to oops.

Romain Kuntz 21caa6622b ipv6: use addrconf_get_prefix_route for prefix route lookup [v2]
Replace ip6_route_lookup() with addrconf_get_prefix_route() when
looking up for a prefix route. This ensures that the connected prefix
is looked up in the main table, and avoids the selection of other
matching routes located in different tables as well as blackhole
or prohibited entries.

In addition, this fixes an Opps introduced by commit 64c6d08e (ipv6:
del unreachable route when an addr is deleted on lo), that would occur
when a blackhole or prohibited entry is selected by ip6_route_lookup().
Such entries have a NULL rt6i_table argument, which is accessed by
__ip6_del_rt() when trying to lock rt6i_table->tb6_lock.

The function addrconf_is_prefix_route() is not used anymore and is
removed.

[v2] Minor indentation cleanup and log updates.

The tests on the flags in addrconf_get_prefix_route() does no make
much sense: the 'noflags' parameter contains the set of flags that
must not match with the route flags, so the test must be done
