Merge 'net' bug fixes into 'net-next' as we have patches
that will build on top of them.
This merge commit includes a change from Emil Goode
(emilgoode@gmail.com) that fixes a warning that would
have been introduced by this merge. Specifically it
fixes the pingv6_ops method ipv6_chk_addr() to add a
"const" to the "struct net_device *dev" argument and
likewise update the dummy_ipv6_chk_addr() declaration.

Added code to initiate FW dump via ethtool. Driver checks if the previous dump
has been cleared before initiating the dump. It doesn't initiate the dump
if it is not cleared.

The SLIPORT_SEMAPHORE register shadowed in the
config-space may not reflect the correct POST stage after
an EEH reset in BE2/3; it may return FW_READY state even though
FW is not ready. This causes the driver to prematurely
poll the FW mailbox and fail.
For BE2/3 use the CSR-BAR/0xac instead.

The SEMAPHORE register was being accessed from the csr BAR space. This BAR
may not be available in some Skyhawk-R configurations. Instead, access this
register via the PCI config space (it's available there too).

The CUST_SCRATCHPAD_CSR register is used for marking if FW cleanup is
needed. This is used in a crash kernel scenario. Do no use this register as
it is not available for some functions. Instead, always issue an FLR when
a function is probed *except* when VFs are preset (enabled in the previous
PF load).

Pull InfiniBand/RDMA changes from Roland Dreier:
- Add ocrdma hardware driver for Emulex IB-over-Ethernet adapters

applications to send and receive arbitrary packets directly to/from
the hardware
- Add "doorbell drop" handling to the cxgb4 driver
- A fairly large batch of qib hardware driver changes
- A few fixes for lockdep-detected issues
- A few other miscellaneous fixes and cleanups
Fix up trivial conflict in drivers/net/ethernet/emulex/benet/be.h.

Calling pci_disable_sriov() while VFs are assigned to VMs causes
kernel panic. This patch uses PCI_DEV_FLAGS_ASSIGNED bit state of the
VF's pci_dev to avoid this. Also, the unconditional function reset cmd
issued on a PF probe can delete the VF configuration for the
previously enabled VFs. A scratchpad register is now used to issue a
function reset only when needed (i.e., in a crash dump scenario.)
