o 83xx and 84xx firmware is capable of multiple Tx queues.
This patch will enable multiple Tx queues for 83xx/84xx
series adapters. Max number of Tx queues supported will be 8.

o Current driver has duplicate code for validating user input
for changing Tx/SDS rings using set_channel ethtool interface.
This patch removes duplicate code and refactored Tx/SDS ring
validation for 82xx/83xx/84xx series adapter.
o Refactored code now calculates maximum Tx/Rx ring driver can
support based on Default, NPAR and SRIOV PF/VF mode of driver.

Three mostly trivial conflicts.
The net/bridge/br_private.h conflict was a function signature (argument
addition) change overlapping with the extern removals from Joe Perches.
In drivers/net/netconsole.c we had one change adjusting a printk message
whilst another changed "printk(KERN_INFO" into "pr_info(".
Lastly, the emulex change was a new inline function addition overlapping
with Joe Perches's extern removals.

There are MBIM devices out there reporting
dwNtbInMaxSize=2048 dwNtbOutMaxSize=2048
and since the spec require a datagram max size of at least
2048, this means that a full sized datagram will never fit.
Still, sending larger NTBs than the device supports is not
going to help. We do not have any other options than either
a) refusing to bindi, or
b) respect the insanely low value.
Alternative b will at least make these devices work, so go
for it.

Padding NTBs to max size is part of the support for devices
optimizing their DMA transfers. This optimization depends on

These fields are only used to prevent printing the same speeds
multiple times if we receive multiple identical speed notifications.
The value of these printk's is questionable, and even more so when
we filter out some of the notifications sent us by the firmware. If
we are going to print any of these, then we should print them all.
Removing little used fields is a bonus.

We can avoid the costly division for the common case where
we pad the frame to tx_max size as long as we ensure that
tx_max is either the device specified dwNtbOutMaxSize or not
a multiplum of wMaxPacketSize.
Using the preconverted 'maxpacket' field avoids converting
wMaxPacketSize to CPU endianness for every transmitted frame
And since we only will hit the one byte padding rule for short
frames, we can drop testing the skb for tailroom.
The change means that tx_max now represents the real maximum
skb size, enabling us to allocate the correct size instead of
always making room for one extra byte.

A number of devices in the wild have turned out to require ZLPs.
Even if this is a spec violation, our priority is to make any
device work as good as possible. Devices needing ZLPs will fail
to receive any full sized frame we send. On the other hand,
devices which do not need the ZLP will still work if we send
them.
This gives us no other option than sending ZLPs by default.
This will prevent devices conforming to the spec from making the
optimizations which are possible without ZLPs. Adding known
such devices to a whitelist, to avoid the possible negative
impact of the new spec violating default.

MBIM is a point-to-point protocol transporting raw IP packets
with no L2 headers. Only IPv4 and IPv6 are supported. ARP in
particular is not, which is quite logical given the lack of
L2 headers.
The driver still emulates an ethernet interface, dropping all
unsupported protocols, and avoiding neigbour resolving by
setting the IFF_NOARP flag.
The MBIM specification does not explicitly forbid IPv6 Neighbor
Discovery, and it seems the other OS support will respond to
Neighbor Solicitations on MBIM links. There are therefore
buggy devices out there, which despite the pointlessness, still
require Neighbor Discovery for IPv6 over MBIM.
This is incompatible with the IFF_NOARP flag which disables
both ARP and ND. We cannot support ARP in any case, so we
have to keep that flag. This patch implements a workaround
for the buggy devices, letting the driver respond directly
to Neighbor Solicitations from the device.
This is not optimal, but will have minimal effect on any sane
device.

Jeff Kirsher says:
====================
This series contains updates to e1000, igb, ixgbe and ixgbevf.
Hong Zhiguo provides a fix for e1000 where tx_ring and adapter->tx_ring
are already of type "struct e1000_tx_ring" so no need to divide by
e1000_tx_ring size in the idx calculation.
Emil provides a fix for ixgbevf to remove a redundant workaround related
to header split and a fix for ixgbe to resolve an issue where the MTA table
can be cleared when the interface is reset while in promisc mode.
Todd provides a fix for igb to prevent ethtool from writing to the iNVM
in i210/i211 devices. This issue was reported by Marek Vasut <[email protected]>.
Anton Blanchard provides a fix for ixgbe to reduce memory consumption
with larger page sizes, seen on PPC.
Don provides a cleanup in ixgbe to replace the IXGBE_DESC_UNUSED macro with
the inline function ixgbevf_desc_unused() to make the logic a bit more
readable.

The ixgbe driver allocates pages for its receive rings. It currently
uses 512 pages, regardless of page size. During receive handling it
adds the unused part of the page back into the rx ring, avoiding the
need for a new allocation.
On a ppc64 box with 64 threads and 64kB pages, we end up with
512 entries * 64 rx queues * 64kB = 2GB memory used. Even more of a
concern is that we use up 2GB of IOMMU space in order to map all this
memory.
The driver makes a number of decisions based on if PAGE_SIZE is less
than 8kB, so use this as the breakpoint and only allocate 128 entries
on 8kB or larger page sizes.

When using firmware assisted TSO, we use a single DMA mapping for
the linear area of a TSO skb.
We still have to segment the super-packet and insert a descriptor
containing the original headers before each segment of payload, so we
can unmap the linear area only after the last segment is completed.
The unmapping information for the linear area is therefore associated
with the last header descriptor.
We calculate the DMA address to unmap from using the map length and
the invariant that the end of the DMA mapping matches the end of
the data referenced by the last descriptor. But this invariant is
broken when there is TCP payload in the linear area.
Fix this by adding and using an explicit dma_offset field.
