1. Remove old adaptive interrupt moderation code from set/get_coalesce()
2. Add ena_update_rx_rings_intr_moderation() function for updating
nonadaptive interrupt moderation intervals similarly to
ena_update_tx_rings_intr_moderation().
3. Remove checks of multiple unsupported received interrupt coalescing
parameters. This makes code cleaner and cancels the need to update
it every time a new coalescing parameter is invented.

There is a race condition that can occur when calling ena_down().
The ena_clean_tx_irq() - which is a part of the napi handler -
function might wake up the tx queue when the queue is supposed
to be down (during recovery or changing the size of the queues
for example) This causes the ena_start_xmit() function to trigger
and possibly try to access the destroyed queues.
The race is illustrated below:
Flow A: Flow B(napi handler)
ena_down()
netif_carrier_off()
netif_tx_disable()
ena_clean_tx_irq()
netif_tx_wake_queue()
ena_napi_disable_all()
ena_destroy_all_io_queues()
After these flows the tx queue is active and ena_start_xmit() accesses
the destroyed queue which leads to a kernel panic.

Check the BNXT_STATE_OPEN flag instead of netif_running() in
bnxt_set_rx_mode(). If the driver is going through any reset, such
as firmware reset or even TX timeout, it may not be ready to set the RX

the device is opened again later.

the headroom is already added to the handle in the function

The socfpga sub-driver defines an `interface` field in the `socfpga_dwmac`
struct and parses it on init.
The shared `stmmac_probe_config_dt()` function also parses this from the
device-tree and makes it available on the returned `plat_data` (which is
the same data available via `netdev_priv()`).
All that's needed now is to dig that information out, via some
`dev_get_drvdata()` && `netdev_priv()` calls and re-use it.

100GbE Intel Wired LAN Driver Updates 2019-09-12
This series contains updates to ice driver to implement and support
loading a Dynamic Device Personalization (DDP) package from lib/firmware
onto the device.
Paul updates the way the driver version is stored in the driver so that
we can pass the driver version to the firmware. Passing of the driver
version to the firmware is needed for the DDP package to ensure we have
the appropriate support in the driver for the features in the package.
Lukasz fixes how the firmware version is stored to align with how the
firmware stores its own version. Also extended the log message to
display additional useful information such as NVM version, API patch
information and firmware build hash.
Tony adds the needed driver support to check, load and store the DDP
package. Also add support for the ability to load DDP packages intended
for specific hardware devices, as well as what to do when loading of the
DDP package fails to load.

Intel Wired LAN Driver Updates 2019-09-11
This series contains updates to i40e, ixgbe/vf and iavf.
Wenwen Wang fixes a potential memory leak where 3 allocated variables
are not properly cleaned up on failure for ixgbe.
Stefan Assmann fixes a potential kernel panic found when repeatedly
spawning and destroying VFs in i40e when a NULL pointer is dereferenced
due to a race condition. Fixed up the i40e driver to clear the
__I40E_VIRTCHNL_OP_PENDING bit before returning after an invalid
minimum transmit rate is requested. Updates the iavf driver to only
apply the MAC address change when the PF ACK's the requested change.
Tonghao Zhang updates ixgbe to use the skb_get_queue_mapping() API call
instead of the driver accessing the queue mapping directly.
Jake updates i40e to use ktime_get_real_ts64() instead of
ktime_to_timespec64(). Removes the define for bit 0x0001 for cloud
filters, since it is a reserved bit and not a valid type. Also added
code comments to clearly state which bits are reserved and should not be
used or defined for cloud filter adminq command. Clarify the macros
used to specify the cloud filter fields are individual bits, so use the
BIT() macro.
Aleksandr fixes up the print_link_message() to include the "negotiated"
FEC status for i40e.
Czeslaw also adds additional log message for devices without FEC in the
print_link_message() for i40e.
Colin Ian King reduces the object code size by making the array API
static constant.
Magnus fixes a potential receive buffer starvation issue for AF_XDP by
kicking the NAPI context of any queue with an attached AF_XDP zero-copy
socket.
v2: Removed patch 11 from the original series (Alex Duyck's ITR fix),
so that it can be sent to the net tree.

Tx code doesn't clear the descriptors' status after cleaning.
So, if the budget is larger than number of used elems in a ring, some
descriptors will be accounted twice and xsk_umem_complete_tx will move
prod_tail far beyond the prod_head breaking the completion queue ring.
Fix that by limiting the number of descriptors to clean by the number
of used descriptors in the Tx ring.

'ixgbe_xsk_clean_tx_ring()' since we're allowed to directly use

When the RX rings are created they are also populated with buffers
so that packets can be received. Usually these are kernel buffers,
but for AF_XDP in zero-copy mode, these are user-space buffers and
in this case the application might not have sent down any buffers
to the driver at this point. And if no buffers are allocated at ring
creation time, no packets can be received and no interrupts will be
generated so the NAPI poll function that allocates buffers to the
rings will never get executed.
To rectify this, we kick the NAPI context of any queue with an
attached AF_XDP zero-copy socket in two places in the code. Once
after an XDP program has loaded and once after the umem is registered.
This take care of both cases: XDP program gets loaded first then AF_XDP
socket is created, and the reverse, AF_XDP socket is created first,
then XDP program is loaded.

Currently iavf unconditionally applies MAC address change requests. This
brings the VF in a state where it is no longer able to pass traffic if
the PF rejects a MAC filter change for the VF.
A typical scenario for a rejected MAC filter is for an untrusted VF to
request to change the MAC address when an administratively set MAC is
present.
To keep iavf working in this scenario the MAC filter handling in iavf
needs to act on the PF reply regarding the MAC filter change. In the
case of an ack the new MAC address gets set, whereas in the case of a
nack the previous MAC address needs to stay in place.

In-between the MAC & PHY there can be a mode converter, which converts one
mode to another (e.g. GMII-to-RGMII).
The converter, can be passive (i.e. no driver or OS/SW information
required), so the MAC & PHY need to be configured differently.
For the `stmmac` driver, this is implemented via a `mac-mode` property in
the device-tree, which configures the MAC into a certain mode, and for the
PHY a `phy_interface` field will hold the mode of the PHY. The mode of the
PHY will be passed to the PHY and from there-on it work in a different
mode. If unspecified, the default `phy-mode` will be used for both.
