3e403a7777 bonding: make it possible to have unlimited nested upper vlans
Currently we're limited by a constant level of vlan nestings, and fail to
find anything beyound that level (currently 2).

To fix this - remove the limit of nestings when going through device tree,
and when the end device is found - allocate the needed amount of vlan tags
and return them, instead of found/not found.

f174c7ec10 be2net: use adapter->flags to track SRIOV state
The driver so far used adapter->num_vfs value to check if SR-IOV is enabled
or not. But, the patch bec84e6("create optimal number of queues on SR-IOV
config") changed this logic. The adapter->num_vfs value is validated and set
much before SR-IOV is enabled. So, we now use an explicit flag to track
SR-IOV enabled state.

e97e3cda5b be2net: reduce arguments passed to FW-cmd routines
A pointer to adapter struct is passed anyway to all of the FW-cmd routines
in be_cmds.c. For routines which query data from FW, the adapter pointer
is enough to return the queried fields.
There is no need to separately pass pointers to individual members of
the adapter structure. This patch fixes this for be_cmd_get_fw_ver()
and be_cmd_get_fw_cfg() routines.

23fa5c2caa bonding: destroy proc directory only after all bonds are gone
Currently we might arrive to bond_net_exit() with some bonds left (that
were created while the module is unloading). We take care of that by
destroying sysfs (the last possibility to add new bonds) and then
destroying all the remaining bonds.

However, we destroy the /proc/net/bonding directory before destroying those
last bonds, and get a warning that we're trying to destroy a non-empty
proc directory (containing /proc/net/bonding/bondX).

Fix this by moving bond_destroy_proc_dir() after all the bonds are
destroyed, so that we're sure that no bonds exist.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2014-07-16

This series contains updates to i40e only.

Neerav adds support to get the port MAC address from firmware and adds
support to the ndo_get_phys_port_id() callback to provide port specific
unique ids to the netdev layer.

Jakub Kicinski provides 2 fixes, first fixes i40e to never generate a software
time stamp if the hardware time stamp is provided.  Second fixes a race
condition on queueing skb for hardware time by using a simple bit lock to
avoid race conditions and leaking skbs when multiple transmit rings try
to claim time stamping.

Paul does some general cleanup of the driver to remove unneeded spaces,
comments that are no longer valid, and break that will never get touched.

Jacob Keller adds a verbose warning message when the incorrect PF attempts
to control timestamping for a port to which it was not assigned.  The primary
intent of this message is to help debugging the reason why the SIOCSHWSTAMP
ioctl has failed and to help narrow the cause of the issue.

6b794c1cd8 bonding: Do not try to send packets over dead link in TLB mode.
In TLB mode if tlb_dynamic_lb is NOT set, slaves from the bond
group are selected based on the hash distribution. This does not
exclude dead links which are part of the bond. Also if there is a
temporary link event which brings down the interface, packets
hashed on that interface would be dropped too.

This patch fixes these issues and distributes flows across the
UP links only. Also the array construction of links which are
capable of sending packets happen in the control path leaving
only link-selection during the data-path.

One possible side effect of this is - at a link event; all
flows will be shuffled to get good distribution. But impact of
this should be minimum with the assumption that a member or
members of the bond group are not available is a very temporary
situation.
