Jacob Keller b335e75bab ixgbe: change handling of multicast filters
In line with changes done by Alex Duyck regarding unicast filters, we
now only set multicast filters when the interface is not in promiscuous
mode for multicast packets. This also has an impact on the RAR usage
such that SR-IOV has some RARs reserved for its own usage.

Greg Rose f9b4b6278d i40e: Reset the VF upon conflicting VLAN configuration
If a host VMM administrator hoses his VF by assigning a port VLAN after
it is already up and running with implicit permission to set local
VLANs then we print a message warning the host administrator that the
VF driver needs to be reloaded.

In addition we need to knock the VF offline so that it does not continue
to receive traffic not on the port VLAN assigned to it.  So we reset the
VF.  The VF will cease operation and the administrator will be forced to
unload and reload the VF driver to make it work again.

Joe Perches 3dbb7fd247 i40e: Remove casts of pointer to same type
Casting a pointer to a pointer of the same type is pointless,
so remove these unnecessary casts.

Jean Sacren e3e3bfdd1d i40e/i40evf: fix error checking path
The commit 6494294f27 ("i40e/i40evf: Use
dma_set_mask_and_coherent") uses dma_set_mask_and_coherent() to
replace dma_set_coherent_mask() for the benefit of return error.
The conversion brings some confusion in error checking as whether
against DMA_BIT_MASK(64) or DMA_BIT_MASK(32). For one, if error is
zero, the check will be against DMA_BIT_MASK(64) twice. Fix this
error checking by binding the check to the pertinent one.

Jean Sacren 21d3efdc2d i40e: fix function kernel doc description
The commit c7d05ca89f ("i40e: driver ethtool core") introduced the
new function i40e_add_del_fdir_sctpv4() with the kernel doc
description a little bit off. The trivial error was copied over to a
different file by the commit 17a73f6b14 ("i40e: Flow Director
sideband accounting") most recently. Fix the kernel doc with the
correct description for clarity.

Mark Rustad 32c74949b4 ixgbevf: Change ixgbe_read_reg to ixgbevf_read_reg
Change the ixgbe_read_reg function name to ixgbevf_read_reg to
avoid a namespace clash with the ixgbe driver. This will allow
ixgbe to take its register read function out-of-line to reduce
memory footprint.

Jean Sacren 6425f0f353 ixgbe: fix ixgbe_check_reset_blocked() declaration
The commit c97506ab0e ("ixgbe: Add check for FW veto bit")
introduced the new function ixgbe_check_reset_blocked() with a minor
issue in declaration. Fix the declaration by changing the type
specifier to bool as the definition returns a boolean value.
Additionally all ixgbe_check_reset_blocked() callers are expected to
return a boolean value.

ixgbe has a single set of TX time stamping resources per NIC.
Use a simple bit lock to avoid race conditions and leaking skbs
when multiple TX rings try to claim time stamping.
