When EEE support was added to the 28nm EPHY it was assumed that it would
be able to support the standard clause 45 over clause 22 register access
method. It turns out that the PHY does not support that, which is the
very reason for using the indirect shadow mode 2 bank 3 access method.
Implement {read,write}_mmd to allow the standard PHY library routines
pertaining to EEE querying and configuration to work correctly on these
PHYs. This forces us to implement a __phy_set_clr_bits() function that
does not grab the MDIO bus lock since the PHY driver's {read,write}_mmd
functions are always called with that lock held.

Currently, the firmware compatible features are enabled in PF driver
initialization process, but they are not disabled in PF driver
deinitialization process and firmware keeps these features in enabled
status.
In this case, if load an old PF driver (for example, in VM) which not
support the firmware compatible features, firmware will still send mailbox
message to PF when link status changed and PF will print
"un-supported mailbox message, code = 201".
To fix this problem, disable these firmware compatible features in PF
driver deinitialization process.

Currently, the rx vlan filter will always be disabled before selftest and
be enabled after selftest as the rx vlan filter feature is fixed on in
old device earlier than V3.
However, this feature is not fixed in some new devices and it can be
disabled by user. In this case, it is wrong if rx vlan filter is enabled
after selftest. So fix it.

If unicast mac address table is full, and user add a new mac address, the

Currently, if function adds an existing unicast mac address, eventhough

For destroy mqprio is irreversible in stack, so it's unnecessary
to rollback the tc configuration when destroy mqprio failed.
Otherwise, it may cause the configuration being inconsistent
between driver and netstack.
As the failure is usually caused by reset, and the driver will
restore the configuration after reset, so it can keep the
configuration being consistent between driver and hardware.

Currently, in function hns3_nic_set_real_num_queue(), the
driver doesn't report the queue count and offset for disabled
tc. If user enables multiple TCs, but only maps user
priorities to partial of them, it may cause the queue range
of the unmapped TC being displayed abnormally.
Fix it by removing the tc enable checking, ensure the queue
count is not zero.
With this change, the tc_en is useless now, so remove it.

hns3_nic_net_open() is not allowed to called repeatly, but there
is no checking for this. When doing device reset and setup tc
concurrently, there is a small oppotunity to call hns3_nic_net_open
repeatedly, and cause kernel bug by calling napi_enable twice.

Currently, we tie the struct mctp_dev lifetime to the underlying struct
net_device, and hold/put that device as a proxy for a separate mctp_dev
refcount. This works because we're not holding any references to the
mctp_dev that are different from the netdev lifetime.
In a future change we'll break that assumption though, as we'll need to
hold mctp_dev references in a workqueue, which might live past the
netdev unregister notification.
In order to support that, this change introduces a refcount on the
mctp_dev, currently taken by the net_device->mctp_ptr reference, and
released on netdev unregister events. We can then use this for future
references that might outlast the net device.

We will want to invalidate sk_keys in a future change, which will
require a boolean flag to mark invalidated items in the socket & net
namespace lists. We'll also need to take a reference to keys, held over
non-atomic contexts, so we need a refcount on keys also.
This change adds a validity flag (currently always true) and refcount to
struct mctp_sk_key. With a refcount on the keys, using RCU no longer
makes much sense; we have exact indications on the lifetime of keys. So,
we also change the RCU list traversal to a locked implementation.

The ixgbe driver currently generates a NULL pointer dereference with
some machine (online cpus < 63). This is due to the fact that the
maximum value of num_xdp_queues is nr_cpu_ids. Code is in
"ixgbe_set_rss_queues"".
Here's how the problem repeats itself:
Some machine (online cpus < 63), And user set num_queues to 63 through
ethtool. Code is in the "ixgbe_set_channels",
adapter->ring_feature[RING_F_FDIR].limit = count;
It becomes 63.
When user use xdp, "ixgbe_set_rss_queues" will set queues num.
adapter->num_rx_queues = rss_i;
adapter->num_tx_queues = rss_i;
adapter->num_xdp_queues = ixgbe_xdp_queues(adapter);
And rss_i's value is from
f = &adapter->ring_feature[RING_F_FDIR];
rss_i = f->indices = f->limit;
So "num_rx_queues" > "num_xdp_queues", when run to "ixgbe_xdp_setup",
for (i = 0; i < adapter->num_rx_queues; i++)
if (adapter->xdp_ring[i]->xsk_umem)
It leads to panic.

octeontx2: Add PTP support for VFs
PTP is a shared hardware block which can prepend
RX timestamps to packets before directing packets to
PFs or VFs and can notify the TX timestamps to PFs or VFs
via TX completion queue descriptors. Hence adding PTP
support for VFs is exactly similar to PFs with minimal changes.
This patchset adds that PTP support for VFs.
Patch 1 - When an interface is set in promisc/multicast
the same setting is not retained when changing mtu or channels.
This is due to toggling of the interface by driver but not
calling set_rx_mode in the down-up sequence. Since setting
an interface to multicast properly is required for ptp this is
addressed in this patch.
Patch 2 - Changes in VF driver for registering timestamping
ethtool ops and ndo_ioctl.

Whenever the interface is brought up/down then set_rx_mode
function is called by the stack which enables promisc/allmulti

interface down and then up such as while changing number
of channels. In these cases promisc/allmulti MCAM entries
are left disabled as set_rx_mode callback is not called.

The second resource is optional which is only provided on the chipset
IPQ5018. But the blamed commit ignores that and if the resource is
not there it just fails.
the resource is used like this,
if (priv->eth_ldo_rdy) {
val = readl(priv->eth_ldo_rdy);
val |= BIT(0);
writel(val, priv->eth_ldo_rdy);
fsleep(IPQ_PHY_SET_DELAY_US);
}
This patch reverts that to still allow the second resource to be optional
because other SoC have the some MDIO controller and doesn't need to
second resource.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.
In this case this is not actually dynamic sizes: both sides of the
multiplication are constant values. However it is best to refactor this
anyway, just to keep the open-coded math idiom out of code.
So, use the purpose specific kcalloc() function instead of the argument
size * count in the kzalloc() function.

After commit a8f89fa27773 ("ice: do not abort devlink info if board
identifier can't be found"), the getter/fallback() functions no longer
report an error. Convert the interface to a void so that it is no
longer possible to add a version field that is fatal. This makes
sense, because we should not fail to report other versions just
because one of the version pieces could not be found.
Finally, clean up the getter functions line wrapping so that none of
them take more than 80 columns, as is the usual style for networking
files.

DSCP a.k.a L3 QoS is only supported on certain devices. To enforce this,
this patch introduces a bitmap of features and helper functions.
The feature bitmap is set based on device IDs on driver init. Currently,
DSCP is the only feature in this bitmap, but there will be more in the
future. In the DCB netlink flow, check if the feature bit is set before
exercising DSCP.

Implement code to handle submission of APP TLV's
containing DSCP to TC mapping.
The first such mapping received on an interface
will cause that PF to switch to L3 DSCP QoS mode,
apply the default config for that mode, and apply
the received mapping.
Only one such mapping will be allowed per DSCP value,
and when the last DSCP mapping is deleted, the PF
will switch back into L2 VLAN QoS mode, applying the
appropriate default QoS settings.
L3 DSCP QoS mode will only be allowed in SW DCBx
mode, in other words, when the FW LLDP engine is
disabled. Commands that break this mutual exclusivity
will be blocked.

The use of dma_unmap_addr()/dma_unmap_len() in the driver causes
multiple warnings when these macros are defined as empty, e.g.
in an ARCH=i386 allmodconfig build:
drivers/net/ethernet/google/gve/gve_tx_dqo.c: In function 'gve_tx_add_skb_no_copy_dqo':
drivers/net/ethernet/google/gve/gve_tx_dqo.c:494:40: error: unused variable 'buf' [-Werror=unused-variable]
494 | struct gve_tx_dma_buf *buf =
This is not how the NEED_DMA_MAP_STATE macros are meant to work,
as they rely on never using local variables or a temporary structure
like gve_tx_dma_buf.
Remote the gve_tx_dma_buf definition and open-code the contents
in all places to avoid the warning. This causes some rather long
lines but otherwise ends up making the driver slightly smaller.

Current driver uses software CQ head pointer to poll on CQE
header in memory to determine if CQE is valid. Software needs
to make sure, that the reads of the CQE do not get re-ordered
so much that it ends up with an inconsistent view of the CQE.
To ensure that DMB barrier after read to first CQE cacheline
and before reading of the rest of the CQE is needed.
But having barrier for every CQE read will impact the performance,
instead use hardware CQ head and tail pointers to find the
valid number of CQEs.
