sparse warning that is not a problem.
Paul allows for HW initialization to continue if PHY abilities cannot

Jeb removes bypassing FW link override and reading Option ROM and
netlist information for non-E810 devices as this is now available on
other devices.
Nick removes vlan_ena field as this information can be gathered by
checking num_vlan.
Jake combines format strings and debug prints to the same line.
Simon adds a space to fix string concatenation.
v4: Drop ACL patches. Change PHY abilities failure message from debug to
warning.
v3: Fix email address for DaveM and fix character in cover letter
v2: Expand on commit message for patch 3 to show example usage/commands.
Reduce number of defensive checks being done.

Change interrupt trigger from IRQ_TYPE_LEVEL_HIGH to IRQ_TYPE_EDGE_RISING
for stable NFC I2C interrupt handling.
Samsung's NFC Firmware sends an i2c frame as below.
1. NFC Firmware sets the GPIO(interrupt pin) high when there is an i2c
frame to send.
2. If the CPU's I2C master has received the i2c frame, NFC F/W sets the
GPIO low.
NFC driver's i2c interrupt handler would be called in the abnormal case
as the NFC FW task of number 2 is delayed because of other high priority
tasks.
In that case, NFC driver will try to receive the i2c frame but there isn't
any i2c frame to send in NFC.
It would cause an I2C communication problem. This case would hardly happen.
But, I changed the interrupt as a defense code.
If Driver uses the TRIGGER_RISING instead of the LEVEL trigger,
there would be no problem even if the NFC FW task is delayed.

The function increases a single stat at a time and several stats which
are increased together weren't put into a function to avoid
calling the function several times for each stat which looks bad and
might decrease performance.

net: ena: use constant value for net_device allocation
The patch changes the maximum number of RX/TX queues it advertises to
the kernel (via alloc_etherdev_mq()) from a value received from the
device to a constant value which is the minimum between 128 and the
number of CPUs in the system.
By allocating the net_device struct with a constant number of queues,
the driver is able to allocate it at a much earlier stage, before
calling any ena_com functions. This would allow to make all log prints
in ena_com to use netdev_* log functions instead or current pr_* ones.
Note:
netdev_* prints in ena_com functions that are called before
net_device registration in ena_probe() might print messages that are
a bit ugly (with strings like "(unnamed net_device) (uninitialized)").
However we decided to use netdev_* prints in these functions anyway,
for the sake of getting better messages later, when ena_com functions
are called after ena_probe() form other parts of the driver.

====================
GVE Raw Addressing
Patchset description:
This patchset introduces "raw addressing" mode to the GVE driver.
Previously (in "queue_page_list" or "qpl" mode), the driver would
pre-allocate and dma_map buffers to be used on egress and ingress.
On egress, it would copy data from the skb provided to the
pre-allocated buffers - this was expensive.
In raw addressing mode, the driver can avoid this copy and simply
dma_map the skb's data so that the NIC can use it.
On ingress, the driver passes buffers up to the networking stack and
then frees and reallocates buffers when necessary instead of using
skb_copy_to_linear_data.
Patch 3 separates the page refcount tracking mechanism
into a function gve_rx_can_recycle_buffer which uses get_page - this will
be changed in a future patch to eliminate the use of get_page in tracking
page refcounts.

====================
mlxsw: Add support for Q-in-VNI
This patch set adds support for Q-in-VNI over Spectrum-{2,3} ASICs.
Q-in-VNI is like regular VxLAN encapsulation with the sole difference
that overlay packets can contain a VLAN tag. In Linux, this is achieved
by adding the VxLAN device to a 802.1ad bridge instead of a 802.1q
bridge.
From mlxsw perspective, Q-in-VNI support entails two main changes:
1. An outer VLAN tag should always be pushed to the overlay packet
during decapsulation
2. The EtherType used during decapsulation should be 802.1ad (0x88a8)
instead of the default 802.1q (0x8100)
Patch set overview:
Patches #1-#3 add required device registers and fields
Patch #4 performs small refactoring to allow code re-use
Patches #5-#7 make the EtherType used during decapsulation a property of
the tunnel port (i.e., VxLAN). This leads to the driver vetoing
configurations in which VxLAN devices are member in both 802.1ad and
802.1q/802.1d bridges. Will be handled in the future by determining the
overlay EtherType on the egress port instead
Patch #8 adds support for Q-in-VNI for Spectrum-2 and newer ASICs
Patches #9-#10 veto Q-in-VNI for Spectrum-1 ASICs due to some hardware
limitations. Can be worked around, but decided not to support it for now
Patch #11 adjusts mlxsw to stop vetoing addition of VXLAN devices to
802.1ad bridges
Patch #12 adds a generic forwarding test that can be used with both veth
pairs and physical ports with a loopback
Patch #13 adds a test to make sure mlxsw vetoes unsupported Q-in-VNI
configurations

mlxsw_sp_bridge_8021q_vxlan_join() because VLANs were only ever added to
a VLAN-filtering bridge, which is only 802.1q bridge.
This set adds support for VxLAN with 802.1ad bridge, so VLAN-filtering
bridge is not only 802.1q.
Call ops->vxlan_join(), so mlxsw_sp_bridge_802{1q, 1ad}_vxlan_join()
will be called according to bridge type.
This is needed to ensure that VxLAN with 802.1ad bridge will be vetoed
in Spectrum-1 with the next patch.

mlx5-updates-2020-12-01
mlx5e port TX timestamping support and MISC updates
1) Add support for port TX timestamping, for better PTP accuracy.
Currently in mlx5 HW TX timestamping is done on CQE (TX completion)
generation, which much earlier than when the packet actually goes out to
the wire, in this series Eran implements the option to do timestamping on
the port using a special SQ (Send Queue), such Send Queue will generate 2
CQEs (TX completions), the original one and a new one when the packet
leaves the port, due to the nature of this special handling, such mechanism
is an opt-in only and it is off by default to avoid any performance
degradation on normal traffic flows.
This patchset improves TX Hardware timestamping offset to be less than
40ns at a 100Gbps line rate, compared to 600ns before.
With that, making our HW compliant with G.8273.2 class C, and allow Linux
systems to be deployed in the 5G telco edge, where this standard is a must.
2) Misc updates and trivial improvements.

net: hns3: refine the VLAN tag handle for port based VLAN
For DEVICE_VERSION_V2, the hardware only supports max two layer
VLAN tags, including port based tag inserted by hardware, tag in
tx buffer descriptor(get from skb->tci) and tag in packet.
For transmit packet:
If port based VLAN disabled, and vf driver gets a VLAN tag from
skb, the VLAN tag must be filled to the Outer_VLAN_TAG field
(tag near to DMAC) of tx buffer descriptor, otherwise it may
be inserted after the tag in packet.
If port based VLAN enabled, and vf driver gets a VLAN tag from
skb, the VLAN tag must be filled to the VLAN_TAG field (tag
far to DMAC) of tx buffer descriptor, otherwise it may be
conflicted with port based VLAN, and raise a hardware error.
For receive packet:
The hardware will strip the VLAN tags and fill them in the rx
buffer descriptor, no matter port based VLAN enable or not.
Because port based VLAN tag is useless for stack, so vf driver
needs to discard the port based VLAN tag get from rx buffer
descriptor when port based VLAN enabled.
So vf must know about the port based VLAN state.
For DEVICE_VERSION_V3, the hardware provides some new
configuration to improve it.
For transmit packet:
When enable tag shift mode, hardware will handle the VLAN tag
in outer_VLAN_TAG field as VLAN_TAG, so it won't conflict with
port based VLAN. And hardware also make sure the tag before
the tag in packet. So vf driver doesn't need to specify the tag
position according to the port based VLAN state anymore.
For receive packet:
When enable discard mode, hardware will strip and discard the
port based VLAN tag, so vf driver doesn't need to identify it
from rx buffer descriptor.
So modify the port based VLAN configuration, simplify the process
for vf handling the VLAN tag.
