RFC4862 states that "In all cases, a node MUST NOT respond to
a Neighbor Solicitation for a tentative address".
Currently the driver configures the NS offload and does not wait
for address to become permanent, thus violating the RFC.
Just removing the address from the address list is not good enough
for all cases, since the NS messages are needed for the duplicate
address detection and should not be discarded.
For d0i3 disable NS offload. Put tentative address in the address
list so the NS packet will not be filtered out by ucode.
For D3 the platform will not wake from NS packets - so enable
NS offload while removing the tentative address from the list.
Given that now NS offload might be disabled, and that the ucode
uses the IP data for other puroposes (L3 filtering) add two
independent flags indicating if IPv4\IPv6 data is valid.

Today, in order to configure fw in usniffer mode, the ucode
must have the corresponding tlv, which is revealed to the driver
while parsing the ucode.
Expose the mode of the usniffer to other utilities in the driver
(other than the ucode parser) by passing back a pointer to the value.
This can be very useful for allowing configuring the fw dbg data
using an external configuration file, because this configuration
depends on the fw usniffer mode.

stmmac_config_sub_second_increment set the sub second increment to 20ns.
Driver is configured to use the fine adjustment method where the sub second
register is incremented when the acculumator incremented by the addend
register wraps overflows. This accumulator is update on every ptp clk
cycle. If a ptp clk with a period of greater than 20ns was used the
sub second register would not get updated correctly.
Instead set the sub sec increment to twice the period of the ptp clk.
This result in the addend register being set mid range and overflow
the accumlator every 2 clock cycles.

The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the
set of features for offloading all checksums. This is a mask of the
checksum offload related features bits. It is incorrect to set both
NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for
features of a device.
This patch:
- Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where
NETIF_F_ALL_CSUM is being used as a mask).
- Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to
use NEITF_F_HW_CSUM in features list instead of NETIF_F_ALL_CSUM.

for IP protocols. This offload interface is also very different.

When creating a VLAN device on top of LAG, we are basically creating a
vPort on top of each of the port netdevs member in the LAG. Therefore,
these vPorts should inherit both the LAG status and LAG ID from the
underlying port netdevs.
In addition, when the VLAN device joins or leaves a bridge each of the
underlying vPorts should know about it and act accordingly. This is
achieved by propagating the VLAN event down to the lower devices.

All the member VLAN devices in a bridge need to share the same vFID.
To achieve that, expand the vFID struct to include the associated bridge
device (or lack of) and allow one to lookup a vFID based on a bridge
device.
When joining a bridge, lookup the relevant vFID or create one if none
exists. Next, make the VLAN device use the vFID.
Leaving a bridge can either occur because a user removed the VLAN device
from a bridge or because the VLAN device was deleted by the user. In the
latter case the bridge's teardown sequence is invoked after the hardware
vPort is already gone. Therefore, when unlinking the VLAN device from
the real device, check if the associated vPort is bridged and act
accordingly. The bridge's notification will be ignored in this case.
Note that bridging a VLAN interface with an ordinary port netdev is
currently not supported, but not forbidden. This will be addressed in a
follow-up patchset.

When a VLAN interface is configured on top of a physical port we should
associate the VLAN device with the matching vPort. Likewise, when it's
removed, we should revert back to the underlying port netdev.
While not a must, this is consistent with port netdevs and also provides
a more accurate error printing via netdev_err() and friends.

FDB notifications contain the FID and port (or LAG ID) on which the MAC
was learned. In the case of the 802.1Q bridge one can easily derive the
matching VID - as FID equals VID - and generate the appropriate
notification for the software bridge. With VLAN devices this is no
longer the case, as these are associated with a vFID.
Solve that by converting the FID to a vFID and lookup the matching VLAN
device. From that derive the VID and whether learning (and learning
sync) should occur.

so, act accordingly, otherwise continue as usual.

In the Spectrum ASIC - unlike SwitchX-2 - FDB access is done by
specifying FID as parameter and not VID.
Change the relevant variables and parameters names to reflect that.
Note that this was OK up until now, since FID was always equal to VID,

We previously used only one flood table for packets classified to vFIDs.
However, since we are going to add support for bridges between VLAN
interfaces (mapped to vFIDs) we need to add one more flood table.
That way we can separate the flooding domain of unknown unicast traffic
from all the rest and support flood control (as we do with the 802.1Q
bridge).

Up until now we used a 1:1 mapping - based on VID - to map a VLAN
interface to a vFID. However, a different scheme is needed in order to
support bridges between VLAN interfaces, as all the member interfaces -
which can have different VIDs - need to share the same vFID.
Solve that by splitting the vFID range in two:
1. Non-bridged VLAN interfaces
2. Bridged VLAN interfaces
When a VLAN interface is created, assign it the next available vFID in
the first range, unless one already exists for that VID or number of
vFIDs in the range was exceeded. When interface is removed, free the
vFID, unless other interfaces are mapped to it.
To accomplish the above:
1. Store the VID to vFID mapping in a new struct (mlxsw_sp_vfid), which
has a global context and holds a reference count.
2. Create a vPort (dummy in case of bridge SELF invocation) on top of
of the physical port and hold a reference to the associated vFID.

When adding support for bridges between VLAN interfaces, we'll introduce
a new entity called a vPort, which is a represntation of the VLAN
interface in the hardware.
The main difference between a vPort and a physical port is that several
FIDs can be bound to the latter, whereas only one (called a vFID) can be
bound to the first.
Therefore, it makes sense to use the same struct to represent the two,
but to only allocate the 'active_vlans' bitmap in case of a physical
port.

1GbE Intel Wired LAN Driver Updates 2015-12-14
This series contains updates to e1000e and igb.
Alex Duyck changes e1000_up() to void since it always returned 0, also
by making it void, we can drop some code since we no longer have to worry
about non-zero return values.
Aaron Sierra removes GS40G specific defines and functions since the i210
internal PHY can be accessed with the access functions shared by 82580,
i350 and i354 devices. Also removes the code to add the PHY address into
the PCDL register address, since there is no real reason to do so.
Joe updates the cable length function reports all four pairs true min, max
and average cable length for i210. Also updated ethtool to use enum-based
labels instead of hard coded values.
Benjamin Poirier cleans up code that is never reachable since MSI-X
interrupts are not shared in e1000e. Also removes the ICR read in the
other interrupt handler, since the information is not needed and IMS is
configured such that the only link status change can trigger the other
interrupt handler. Fixed in MSI-X mode, there is no handler for the LSC
interrupt so there is no point in writing that to ICS now that we always
assume other interrupts are caused by LSC.

Since the introduction of 82574 support in e1000e, the driver has worked
on the assumption that msi-x interrupt generation is automatically
disabled after each irq. As it turns out, this is not the case.
Currently, rx interrupts can fire multiple times before and during napi
processing. This can be a problem for users because frames that arrive
in a certain window (after adapter->clean_rx() but before
napi_complete_done() has cleared NAPI_STATE_SCHED) generate an interrupt
which does not lead to napi_schedule(). These frames sit in the rx queue
until another frame arrives (a tcp retransmit for example).
While the EIAC and CTRL_EXT registers are properly configured for irq
automask, the modification of IAM in e1000_configure_msix() is what
prevents automask from working as intended.
This patch removes that erroneous write and fixes interrupt rearming for
tx interrupts. It also clears IAME from CTRL_EXT. This is not strictly
necessary for operation of the driver but it is to avoid disruption from
potential programs that access the registers directly, like `ethregs -c`.
