Nonadaptive interrupt moderation intervals are assigned the value set
by the user in ethtool -C divided by ena_dev->intr_delay_resolution.
Therefore when the user tries to get the nonadaptive interrupt moderation
intervals with ethtool -c the code needs to multiply the saved value
by ena_dev->intr_delay_resolution.
The current code erroneously divides instead of multiplying in ethtool -c.
This patch fixes this.

Current implementation always updates the interrupt register with
the smoothed_interval of the rx_ring. However this should be
done only in case of adaptive interrupt moderation. If non-adaptive
interrupt moderation is used, the non-adaptive interrupt moderation
interval should be used. This commit fixes that.

1. Out of the fields {per_napi_bytes, per_napi_packets} in struct ena_ring,
only rx_ring->per_napi_packets are used to determine if napi did work
for dim.
This commit removes all other uses of these fields.
2. Remove ena_ring->moder_tbl_idx, which is not used by dim.
3. Remove all calls to ena_com_destroy_interrupt_moderation(), since all it
did was to destroy the interrupt moderation table, which is removed as
part of removing old interrupt moderation code.

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

This driver becomes the first user of the kernel's `ETHTOOL_PHY_EDPD`
phy-tunable feature.
EDPD is also enabled by default on PHY config_init, but can be disabled via
the phy-tunable control.
When enabling EDPD, it's also a good idea (for the ADIN PHYs) to enable TX
periodic pulses, so that in case the other PHY is also on EDPD mode, there
is no lock-up situation where both sides are waiting for the other to
transmit.
Via the phy-tunable control, TX pulses can be disabled if specifying 0
`tx-interval` via ethtool.
The ADIN PHY supports only fixed 1 second intervals; they cannot be
configured. That is why the acceptable values are 1,
ETHTOOL_PHY_EDPD_DFLT_TX_MSECS and ETHTOOL_PHY_EDPD_NO_TX (which disables
TX pulses).

When skb_shinfo(skb) is not able to cache extra fragment (that is,
skb_shinfo(skb)->nr_frags >= MAX_SKB_FRAGS), xennet_fill_frags() assumes
the sk_buff_head list is already empty. As a result, cons is increased only
by 1 and returns to error handling path in xennet_poll().
However, if the sk_buff_head list is not empty, queue->rx.rsp_cons may be
set incorrectly. That is, queue->rx.rsp_cons would point to the rx ring
buffer entries whose queue->rx_skbs[i] and queue->grant_rx_ref[i] are
already cleared to NULL. This leads to NULL pointer access in the next
iteration to process rx ring buffer entries.
Below is how xennet_poll() does error handling. All remaining entries in
tmpq are accounted to queue->rx.rsp_cons without assuming how many
outstanding skbs are remained in the list.
985 static int xennet_poll(struct napi_struct *napi, int budget)
... ...
1032 if (unlikely(xennet_set_skb_gso(skb, gso))) {
1033 __skb_queue_head(&tmpq, skb);
1034 queue->rx.rsp_cons += skb_queue_len(&tmpq);
1035 goto err;
1036 }
It is better to always have the error handling in the same way.

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.

This qdisc offload is the closest thing to what the SJA1105 supports in
hardware for time-based egress shaping. The switch core really is built
around SAE AS6802/TTEthernet (a TTTech standard) but can be made to
operate similarly to IEEE 802.1Qbv with some constraints:
- The gate control list is a global list for all ports. There are 8
execution threads that iterate through this global list in parallel.
I don't know why 8, there are only 4 front-panel ports.
- Care must be taken by the user to make sure that two execution threads
never get to execute a GCL entry simultaneously. I created a O(n^4)
checker for this hardware limitation, prior to accepting a taprio
offload configuration as valid.
- The spec says that if a GCL entry's interval is shorter than the frame
length, you shouldn't send it (and end up in head-of-line blocking).
Well, this switch does anyway.
- The switch has no concept of ADMIN and OPER configurations. Because
it's so simple, the TAS settings are loaded through the static config
tables interface, so there isn't even place for any discussion about
'graceful switchover between ADMIN and OPER'. You just reset the
switch and upload a new OPER config.
- The switch accepts multiple time sources for the gate events. Right
now I am using the standalone clock source as opposed to PTP. So the
base time parameter doesn't really do much. Support for the PTP clock
source will be added in a future series.

This is a preparation patch for the tc-taprio offload (and potentially
for other future offloads such as tc-mqprio).
Instead of looking directly at skb->priority during xmit, let's get the
netdev queue and the queue-to-traffic-class mapping, and put the
resulting traffic class into the dsa_8021q PCP field. The switch is
configured with a 1-to-1 PCP-to-ingress-queue-to-egress-queue mapping
(see vlan_pmap in sja1105_main.c), so the effect is that we can inject
into a front-panel's egress traffic class through VLAN tagging from
Linux, completely transparently.
Unfortunately the switch doesn't look at the VLAN PCP in the case of
management traffic to/from the CPU (link-local frames at
01-80-C2-xx-xx-xx or 01-1B-19-xx-xx-xx) so we can't alter the
transmission queue of this type of traffic on a frame-by-frame basis. It
is only selected through the "hostprio" setting which ATM is harcoded in
the driver to 7.

The cited commit introduced a double-free of the srq buffer in the error
flow of procedure __uverbs_create_xsrq().
The problem is that ib_destroy_srq_user() called in the error flow also

Thus, if uverbs_response() fails in __uverbs_create_srq(), the srq buffer
will be freed twice.

The removal of 'buffer' in the patch below caused free_page() to use a
value that had been offset since the wqe pointer is adjusted while the

The current implementation of free_pages() rounds down to a pfn,
discarding the adjustment, but this is not the right way to use the
API. Preserve the initial value and use it for free_page().

The MDIO device reset line is optional and now that gpiod_get_optional()

reason to use fwnode_get_named_gpiod() that I plan to hide away.
Let's switch to using more standard gpiod_get_optional() and
gpiod_set_consumer_name() to keep the nice "PHY reset" label.
Also there is no reason to only try to fetch the reset GPIO when we have
OF node, gpiolib can fetch GPIO data from firmwares as well.

There are two modes for mailbox command (cmd) queue, i.e., event mode and
poll mode. For each mode, we use corresponding semaphores to protect the
cmd queue resource competition, so called event_sem and poll_sem. During
cmd init, both semaphores are initialized and poll mode is selected.
Thus, there is no need to up poll_sema again in cmd_use_polling.
Furthermore, there is no need to down the sema of the other side while
switching mode. This patch aims to decouple the switch between event mode
and poll mode of cmd.

This driver is DT based and utilizes the DesignWare APIs.
It allows using a smaller ECAM range for a larger bus range -
usually an entire bus uses 1MB of address space, but the driver
can use it for a larger number of buses. This is achieved by using a HW
mechanism which allows changing the BUS part of the "final" outgoing
config transaction. There are 2 HW regs, one which is basically a
bitmask determining which bits to take from the AXI transaction itself
and another which holds the complementary part programmed by the
driver.
All link initializations are handled by the boot FW.

The Root Port (identified by [1c36:0031]) doesn't support MSI-X. On some
platforms it is configured to not advertise the capability at all, while
on others it (mistakenly) does. This causes a panic during
initialization by the pcieport driver, since it tries to configure the
MSI-X capability. Specifically, when trying to access the MSI-X table
a "non-existing addr" exception occurs.

pcieport 0001:00:00.0: VPD access failed. This is likely a firmware bug on this device. Contact the card vendor for a firmware update

The Amazon's Annapurna Labs root ports don't advertise an ACS
capability, but they don't allow peer-to-peer transactions and do
validate bus numbers through the SMMU. Additionally, it's not possible
for one RP to pass traffic to another RP.

rbd_dev_image_id() allocates space for length but passes a smaller
value to rbd_obj_method_sync(). rbd_dev_v2_object_prefix() doesn't
allocate space for length. Fix both to be consistent.

Commit 7cbbf9f1fa23 ("ixgbe: fix xdp handle calculations") reintroduced
the addition of the umem headroom to the xdp handle in the ixgbe_zca_free,
ixgbe_alloc_buffer_slow_zc and ixgbe_alloc_buffer_zc functions. However,
the headroom is already added to the handle in the function
ixgbe_run_xdp_zc. This commit removes the latter addition and fixes the
case where the headroom is non-zero.

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.

Using static analysis, I discovered that the "dpriv->pci_priv->pdev"
pointer is always NULL. This pointer was supposed to be initialized
during probe and is essential for the driver to work. It would be easy
to add a "ppriv->pdev = pdev;" to dscc4_found1() but this driver has
been broken since before we started using git and no one has complained
so probably we should just remove it.

We need to hold rnl lock in suspend and resume callbacks because phylink
requires it. Otherwise we will get a WARN() in suspend and resume.
Also, move phylink start and stop callbacks to inside device's internal
lock so that we prevent concurrent HW accesses.
