net: Fix randconfig errros in bnx2i/bnx2fc caused by IPV6
Just like CNIC bnx2i/bnx2fc also have their tristate dependent on IPV6, however
using the same solution as CNIC can cause recursive dependecies during make.

Just like CNIC, tristate of these two modules is also dependent on IPV6.
These need to be handled separately as they select CNIC, which can override
tristate for CNIC from 'm' to 'y', which can cause build failures when ipv6 is
compiled as a module even if CNIC's Kconfig will only 'm' or 'n' when ipv6 is
compiled as a module.

DSA Cleanups
This patch series does two things, first it cleans up the tag_protocol and
protocol ops being configured seperately. Second it addresses the desire
to split DSA away from relying on a MII bus.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This change makes it so that instead of passing and storing a mii_bus we
instead pass and store a host_dev. From there we can test to determine the
exact type of device, and can verify it is the correct device for our switch.
So for example it would be possible to pass a device pointer from a pci_dev
and instead of checking for a PHY ID we could check for a vendor and/or device
ID.

This change addresses several issues.
First, it was possible to set tag_protocol without setting the ops pointer.
To correct that I have reordered things so that rcv is now populated before
we set tag_protocol.
Second, it didn't make much sense to keep setting the device ops each time a
new slave was registered. So by moving the receive portion out into root
switch initialization that issue should be addressed.
Third, I wanted to avoid sending tags if the rcv pointer was not registered
so I changed the tag check to verify if the rcv function pointer is set on
the root tree. If it is then we start sending DSA tagged frames.
Finally I split the device ops pointer in the structures into two spots. I
placed the rcv function pointer in the root switch since this makes it
easiest to access from there, and I placed the xmit function pointer in the
slave for the same reason.

bonding: style, comment and assertion changes
This is a small and simple patch-set that doesn't introduce (hopefully) any
functional changes, but only stylistic and semantic ones.
Patch 01 simply uses the already provided __rlb_next_rx_slave function inside
rlb_next_rx_slave(), thus removing the duplication of code.
Patch 02 changes all comments that I could find to netdev style, removes
some outdated ones and fixes a few more small cosmetic issues (new line
after declaration, braces around if; else and such)
Patch 03 removes one extra ASSERT_RTNL() because we already have it in the
parent function and consolidates two other ASSERT_RTNL()s to the function
that is exported and supposed to be called with RTNL anyway.

First adjust a couple of locking comments that were left inaccurate,
then adjust comments to use the netdev styling and remove extra new
lines where necessary and add a couple of new lines between declarations
and code. These are all trivial styling changes, no functional change.
Also removed a couple of outdated or obvious comments.
This patch is by no means a complete fix of all netdev style violations
but it gets the bonding closer.

__rlb_next_rx_slave() is a copy of rlb_next_rx_slave() with the
difference that it uses rcu primitives to walk the slave list. We don't
need the two functions and can make rlb_next_rx_slave() a wrapper for
callers which hold RTNL.
So add a comment and ASSERT_RTNL() to make sure what is intended.

This patch adds a explicit check in iscsit_find_cmd_from_itt_or_dump()
to ignore commands with ICF_GOT_LAST_DATAOUT set. This is done to
address the case where an ITT is being reused for DataOUT, but the
previous command with the same ITT has not yet been acknowledged by
ExpStatSN and removed from the per connection command list.
This issue was originally manifesting itself by referencing the
previous command during ITT lookup, and subsequently hitting the
check in iscsit_check_dataout_hdr() for ICF_GOT_LAST_DATAOUT, that
resulted in the DataOUT PDU + associated payload being silently
dumped.

It was caused by an uninitialized variable introduced
