This reporter will report NVM errors which are non-fatal.
When we receive these NVM error events, we'll report it
through this new hw health reporter.

Health reporter state should be maintained over resets. Previously
reporters were destroyed if the device capabilities changed, but
since none of the reporters depend on capabilities anymore, this
logic should be removed.

If the flow control settings have been changed, a subsequent FW reset
may cause the ethernet link to toggle unnecessarily. This link toggle
will increase the down time by a few seconds.
The problem is caused by bnxt_update_phy_setting() detecting a false
mismatch in the flow control settings between the stored software
settings and the current FW settings after the FW reset. This mismatch
is caused by the AUTONEG bit added to link_info->req_flow_ctrl in an
inconsistent way in bnxt_set_pauseparam() in autoneg mode. The AUTONEG
bit should not be added to link_info->req_flow_ctrl.

Some cards are configured to never support link pause or PFC. Discover
these cards and properly report no pause support to ethtool. Disable
PFC settings from DCBNL if PFC is unsupported.

Instead of always returning -ENOPKG, decode the firmware error
code further when the HWRM_NVM_INSTALL_UPDATE firmware call fails.
Return a more suitable error code to userspace and log an error

FW returns error code "NVM_INSTALL_UPDATE_CMD_ERR_CODE_ANTI_ROLLBACK"
in the response to indicate that HWRM_NVM_INSTALL_UPDATE command has
failed due to Anti-rollback feature. Parse the error and return an
appropriate error code to the user.

Now that NAPI has been implemented, the hardware interrupt mitigation
mechanism is not needed to avoid excessive interrupt load in most cases.
Reduce the default RX interrupt threshold to 1 to reduce introduced
latency. This can be increased with ethtool if desired if some applications
still want to reduce interrupts.

When the RX or TX coalesce count is set to 1, there's no point in
setting the delay timer value since an interrupt will already be raised
on every packet, and the delay interrupt just causes extra pointless

If a memory allocation error occurred during an attempt to refill a slot
in the RX ring after the packet was received, the hardware tail pointer
would still have been updated to point to or past the slot which remained
marked as previously completed. This would likely result in the DMA engine
raising an error when it eventually tried to use that slot again.
If a slot cannot be refilled, then just stop processing and do not move
the tail pointer past it. On the next attempt, we should skip receiving
the packet from the empty slot and just try to refill it again.
This failure mode has not actually been observed, but was found as part
of other driver updates.

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on
static allocation of IRQ resources in DT core code, this
causes an issue when using hierarchical interrupt domains
using "interrupts" property in the node as this bypassed
the hierarchical setup and messed up the irq chaining.
In preparation for removal of static setup of IRQ resource
from DT core code use platform_get_irq().

There is a conflict between MediaTek wmt event and msft vendor extension
logic in the core layer since 145373cb1b1f ("Bluetooth: Add framework for
Microsoft vendor extension") was introduced because we changed the type of
mediatek wmt event to the type of msft vendor event in the driver.
But the purpose we reported mediatek event to the core layer is for the
diagnostic purpose with that we are able to see the full packet trace via
monitoring socket with btmon. Thus, it is harmless we keep the original
type of mediatek vendor event here to avoid breaking the msft extension
function especially they can be supported by Mediatek chipset like MT7921
, MT7922 devices and future devices.

Since the starting value in the for loop is greater than or equal to 1,
the restriction is CAS_FLAG_REG_PLUS is in the file cassini.h is
defined as 0x1 by macro, and the for loop and if condition is not
satisfied, so the code here is redundant.
Clean up the following smatch warning:
drivers/net/ethernet/sun/cassini.c:3513 cas_start_dma() warn: we never
enter this loop.
drivers/net/ethernet/sun/cassini.c:1239 cas_init_rx_dma() warn: we never

This patch adds zero-copy Rx and Tx support for AF_XDP sockets. It do so
by adding a separate NAPI poll function that is attached to a each
channel when the XSK socket is attached with XDP_SETUP_XSK_POOL, and
restored when the XSK socket is terminated, this is done per channel.
Support for XDP_TX is implemented and the XDP buffer can safely be moved
from the Rx to the Tx queue and correctly freed and returned to the XSK
pool once it's transmitted.
Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS
will allocate a new buffer and copy the zero-copy frame prior
passing it to the kernel stack.
This patch is based on previous work by Jakub Kicinski.

LAN937x T1 switch is based on LAN87xx Phy, so reusing the init script of
the LAN87xx. There is a workaround in accessing the DSP bank register
for LAN937x Phy. Whenever there is a bank switch to DSP registers, then
we need a one dummy read access before proceeding to the actual register
access.
