For ethernet devices, net_device.name will be eth%d before
register_netdev() is called. Don't print the net_device name until
the format string is replaced.

This patch adds the necessary driver support for Management Firmware to
configure the device/firmware with the dcbx results. Management Firmware
is responsible for communicating the DCBX and driving the negotiation,
but the driver has responsibility of receiving async notification and
configuring the results in hw/fw. This patch also adds the dcbx support for
future protocols (e.g., FCoE) as preparation to their imminent submission.

When reopening the network device on ra7795/salvator-x, e.g. after a
DHCP timeout:
IP-Config: Reopening network devices...
genirq: Flags mismatch irq 139. 00000000 (eth0:ch0:rx_be) vs. 00000000 (ravb e6800000.ethernet eth0: cannot request IRQ eth0:ch0:rx_be
IP-Config: Failed to open eth0
IP-Config: No network devices available
The "mismatch" is due to requesting an IRQ that is already in use,
while IRQF_PROBE_SHARED wasn't set.
However, the real cause is that ravb_close() doesn't release any of the
R-Car Gen3-specific secondary IRQs.
Add the missing free_irq() calls to fix this.

10GbE Intel Wired LAN Driver Updates 2016-05-16
This series contains 2 fixes to ixgbe only.
Emil fixes transmit hangs when enabling SRIOV by swapping the parameters
in GENMASK in order to generate the correct mask.
Alex fixes his previous patch b83e30104bd9 ("ixgbe/ixgbevf: Add support
for GSO partial") where he somehow transposed the location of setting
the VLAN features in netdev->features and the configuration of the
vlan_features.

It looks like at some point I somehow transposed the location of setting
the VLAN features in netdev->features and the configuration of the
vlan_features. As a result the driver is now generating a warning about
vlan_features being setup incorrectly.
This patch corrects that by placing the update of netdev->features to
include the VLAN features so that it is after the point where we write
netdev->features into netdev->vlan_features.

In multi-function modes, PFs are currently limited to using 16 VFs -
But that limitation would also currently apply in case there's a single
PCI function exposed, where no such restriction should have existed.
This lifts the restriction for the default mode; User should be able
to start the maximum number of VFs as appear in the PCI config space.

PF updates its VFs' bulletin boards with link configurations whenever
the physical carrier changes or whenever hyper-user explicitly requires
some setting of the VFs link via the hypervisor's PF.
Since the bulletin board is getting cleaned as part of the IOV disable
flow on the PF side, re-enabling sriov would lead to a VF that sees the
carrier as 'down', until an event causing the PF to re-fill the bulletin
with the link configuration would occur.
To fix this we simply refelect the link state during the flows, giving
the later VFs a default reflecting the PFs link state.

This increases TX timeout period from one second to 5 seconds which is
the default value if the driver doesn't explicitly set
net_device->watchdog_timeo.
The one second timeout is too short for W5100 with SPI interface mode
which doesn't support burst READ/WRITE processing in the SPI transfer.
If the packet is transmitted while RX packets are being received at a
very high rate, the TX transmittion work in the workqueue is delayed
and the watchdog timer is expired.

If a counter has the aging flag set when created, it is added to a list
of counters that will be queried periodically from a workqueue. query
result and last use timestamp are cached.
add/del counter must be very efficient since thousands of such
operations might be issued in a second.
There is only a single reference to counters without aging, therefore
no need for locks.
But, counters with aging enabled are stored in a list. In order to make
code as lockless as possible, all the list manipulation and access to
hardware is done from a single context - the periodic counters query
thread.
The hardware supports multiple counters per FTE, however currently we
are using one counter for each FTE.

====================
40GbE Intel Wired LAN Driver Updates 2016-05-14
This series contains updates to i40e and i40evf.
Kevin adds support to disable link on all ports and changes bits set
for telling firmware the PHY needs to be modified by the driver.
Anjali adds a feature to enable/disable all multicast for a trusted
VF. Added priv-flag knob to configure global true promiscuous
support.
Shannon adds the support code for calling the admin queue API call
aq_set_switch_config().
Mitch modifies the VF, to log a message if an untrusted VF attempts to
configure promiscuous mode, but lies to it and returns everything is ok
instead of returning an error. Corrects the logic for reporting the
receive packet hash. Fixed the adding of a broadcast filter for VFs,
since that all VSIs are configured to receive broadcasts as default,
so do not need to add a filter.
Catherine refactors the ethtool get_settings to report the possible
supported link modes from what we know about the current PHY type and
that with the firmware supported PHY types.
Jacob changes the driver to use WARN_ONCE in order to highlight the
issue, but do not display a warning every time when receive hang
message is received.
Akeem corrects receive ptype payload layer for non_tunneled IPv6, when
it should be layer 4 for UDP, instead of layer 3.
Dan Carpenter fixes an uninitialized variable bug.

The current code is more complicated than necessary and can only report
unsupported SFP+ module if it is plugged in after the device is up.
Rename bnxt_port_module_event() to bnxt_get_port_module_status(). We
already have the current module_status in the link_info structure, so
just check that and report any unsupported SFP+ module status. Delete
the unnecessary last_port_module_event. Call this function at the
end of bnxt_open to report unsupported module already plugged in.

The current code has 2 problems:
1. The maximum wait time is not long enough. It is about 60% of the
duration specified by the firmware. It is calling usleep_range(600, 800)
for every 1 msec we are supposed to wait.
2. The granularity of the delay is too coarse. Many simple firmware
commands finish in 25 usec or less.
We fix these 2 issues by multiplying the original 1 msec loop counter by
40 and calling usleep_range(25, 40) for each iteration.
There is also a second delay loop to wait for the last DMA word to
complete. This delay loop should be a very short 5 usec wait.
This change results in much faster bring-up/down time:
Before the patch:
time ip link set p4p1 up
real 0m0.120s
user 0m0.001s
sys 0m0.009s
After the patch:
time ip link set p4p1 up
