Conflicts:
	Documentation/networking/ip-sysctl.txt
	drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c

Both conflicts were simply overlapping context.

A build fix for qlcnic is in here too, simply removing the added
devinit annotations which no longer exist.

Sony Chacko 81d0aeb0a4 qlcnic: flash template based firmware reset recovery
Flash template provides instructions to stop, restart and initalize the
firmware. These instructions are abstracted as a series of read, write and
poll operations on hardware registers. Register information and operation
specifics are not exposed to the driver. Driver reads the template from
flash and executes the instructions located at pre-defined offsets.

Template based firmware reset recovery and initialization mechanism minimize
driver changes as firmware evolves.

The __dev* removal patches for the network drivers ended up messing up

them back up to be properly aligned.

Bonus is that this almost removes 100 lines of code, always a nice

Peter Senna Tschudin 2dfc967191 drivers/net/ethernet/qlogic/qlcnic/qlcnic_main.c: fix error return code
The function qlcnic_probe() return 0 for success and negative value
for most of its internal tests failures. There is one exception
that is error case going to err_out_free_netdev:. For this error case,
the function abort its success execution path, but returns non negative
value, making it difficult for a caller function to notice the error.

This patch fixes the error case that do not return negative value.

This was found by Coccinelle, but the code change was made by hand.
This patch is not robot generated.

A simplified version of the semantic match that finds this problem is
as follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}

Narendra K 68b3f28c11 qlcnic: Fix scheduling while atomic bug
In the device close path, 'qlcnic_fw_destroy_ctx' and
'qlcnic_poll_rsp' call msleep. But  'qlcnic_fw_destroy_ctx' and
'qlcnic_poll_rsp' are called with 'adapter->tx_clean_lock' spin lock
held resulting in scheduling while atomic bug causing the following
trace.

I observed that the commit 012dc19a45
from John Fastabend addresses a similar issue in ixgbevf driver.
Adopting the same approach used in the commit, this patch uses mdelay
to address the issue.

Jon Mason ad95dfc72a qlcnic: remove unnecessary setting of skb->dev
skb->dev is being unnecessarily set before calling eth_type_trans.
eth_type_trans already sets skb->dev to the proper value, thus making this
unnecessary.

David S. Miller 7e52b33bd5 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
	net/ipv6/route.c

This deals with a merge conflict between the net-next addition of the
inetpeer network namespace ops, and Thomas Graf's bug fix in
2a0c451ade which makes sure we don't
register /proc/net/ipv6_route before it is actually safe to do so.

Dan Carpenter 0f6efff925 qlcnic: off by one in qlcnic_init_pci_info()
The adapter->npars[] array has QLCNIC_MAX_PCI_FUNC elements.  We
allocate it that way a few lines earlier in the function.  So this test
is off by one.

Rajesh Borundia 0bb79565aa qlcnic: Fix protcol type in case of inband vlan.
o Use correct l3 (ETH_IP or ETH_IPV6)protcol in case
of inband vlan. Because of incorrect protcol type driver
was setting incorrect opcode. This resulted in adapter calculating
checksum incorrectly.
o Updated driver version to 5.0.29
