e1000e: Link NAPI instances to queues and IRQs

Add support for netdev-genl, allowing users to query IRQ, NAPI, and queue
information.

After this patch is applied, note the IRQs assigned to my NIC:

$ cat /proc/interrupts | grep ens | cut -f1 --delimiter=':'
50
51
52

While e1000e allocates 3 IRQs (RX, TX, and other), it looks like e1000e
only has a single NAPI, so I've associated the NAPI with the RX IRQ (50
on my system, seen above).

Note the output from the cli:

$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \
--dump napi-get --json='{"ifindex": 2}'
[{'id': 145, 'ifindex': 2, 'irq': 50}]

This device supports only 1 rx and 1 tx queue. so querying that:

$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \
--dump queue-get --json='{"ifindex": 2}'
[{'id': 0, 'ifindex': 2, 'napi-id': 145, 'type': 'rx'},
{'id': 0, 'ifindex': 2, 'napi-id': 145, 'type': 'tx'}]

e1000e: Remove duplicated writel() in e1000_configure_tx/rx()

Duplicated register initialization codes exist in e1000_configure_tx()
and e1000_configure_rx().

For example, writel(0, tx_ring->head)

e1000e: Remove duplicated writel() in e1000_configure_tx/rx()

Duplicated register initialization codes exist in e1000_configure_tx()
and e1000_configure_rx().

For example, writel(0, tx_ring->head) writes 0 to tx_ring->head, which
is adapter->hw.hw_addr + E1000_TDH(0).

This initialization is already done in ew32(TDH(0), 0).

ew32(TDH(0), 0) is equivalent to __ew32(hw, E1000_TDH(0), 0). It
executes writel(0, hw->hw_addr + E1000_TDH(0)). Since variable hw is
set to &adapter->hw, it is equal to writel(0, tx_ring->head).

We can remove similar four writel() in e1000_configure_tx() and
e1000_configure_rx().

commit 0845d45e900c ("e1000e: Modify Tx/Rx configurations to avoid
null pointer dereferences in e1000_open") has introduced these
writel(). This commit moved register writing to
e1000_configure_tx/rx(), and as result, it caused duplication in
e1000_configure_tx/rx().

This patch modifies the sequence of register writing, but removing
these writes is safe because the same writes were already there before
the commit.

I also have checked the datasheets [0] [1] and have not found any
description that we need to write RDH, RDT, TDH and TDT registers
twice at initialization. Furthermore, we have tested this patch on an
I219-V device physically.

Sporadic issues, such as PHY access loss, have been observed on I219 (19)

e1000e: avoid failing the system during pm_suspend

Occasionally when the system goes into pm_suspend, the suspend might fail
due to a PHY access error on the network adapter. Previously, this would
have caused the whole system to fail to go to a low power state.
An example of this was reported in the following Bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=205015

[ 1663.694828] e1000e 0000:00:19.0 eth0: Failed to disable ULP
[ 1664.731040] asix 2-3:1.0 eth1: link up, 100Mbps, full-duplex, lpa 0xC1E1
[ 1665.093513] e1000e 0000:00:19.0 eth0: Hardware Error
[ 1665.596760] e1000e 0000:00:19.0: pci_pm_resume+0x0/0x80 returned 0 after 2975399 usecs

and then the system never recovers from it, and all the following suspend failed due to this
[22909.393854] PM: pci_pm_suspend(): e1000e_pm_suspend+0x0/0x760 [e1000e] returns -2
[22909.393858] PM: dpm_run_callback(): pci_pm_suspend+0x0/0x160 returns -2
[22909.393861] PM: Device 0000:00:1f.6 failed to suspend async: error -2

This can be avoided by changing the return values of __e1000_shutdown and
e1000e_pm_suspend functions so that they always return 0 (success). This
is consistent with what other drivers do.

If the e1000e driver encounters a hardware error during suspend, potential
side effects include slightly higher power draw or non-working wake on
LAN. This is preferred to a system-level suspend failure, and a warning
message is written to the system log, so that the user can be aware that
the LAN controller experienced a problem during suspend.

e1000e: Fix S0ix residency on corporate systems

On vPro systems, the configuration of the I219-LM to achieve power
gating and S0ix residency is split between the driver and the CSME FW.
It was discovered that in some scenarios, where the network cable is
connected and then disconnected, S0ix residency is not always reached.
This was root-caused to a subset of I219-LM register writes that are not
performed by the CSME FW. Therefore, the driver should perform these
register writes on corporate setups, regardless of the CSME FW state.

This was discovered on Meteor Lake systems; however it is likely to
appear on other platforms as well.

e1000e: move force SMBUS near the end of enable_ulp function

The commit 861e8086029e ("e1000e: move force SMBUS from enable ulp
function to avoid PHY loss issue") introduces a regression on
PCH_MTP_I219_LM18 (PCIID: 0x8086550A). Without the referred commit, the
ethernet works well after suspend and resume, but after applying the
commit, the ethernet couldn't work anymore after the resume and the
dmesg shows that the NIC link changes to 10Mbps (1000Mbps originally):

[ 43.305084] e1000e 0000:00:1f.6 enp0s31f6: NIC Link is Up 10 Mbps Full Duplex, Flow Control: Rx/Tx

Without the commit, the force SMBUS code will not be executed if
"return 0" or "goto out" is executed in the enable_ulp(), and in my
case, the "goto out" is executed since FWSM_FW_VALID is set. But after
applying the commit, the force SMBUS code will be ran unconditionally.

Here move the force SMBUS code back to enable_ulp() and put it
immediately ahead of hw->phy.ops.release(hw), this could allow the
longest settling time as possible for interface in this function and
doesn't change the original code logic.

The issue was found on a Lenovo laptop with the ethernet hw as below:
00:1f.6 Ethernet controller [0200]: Intel Corporation Device [8086:550a]
(rev 20).

And this patch is verified (cable plug and unplug, system suspend
and resume) on Lenovo laptops with ethernet hw: [8086:550a],
[8086:550b], [8086:15bb], [8086:15be], [8086:1a1f], [8086:1a1c] and
[8086:0dc7].

net: intel: implement modern PM ops declarations

Switch the Intel networking drivers to use the new power management ops
declaration formats and macros, which allows us to drop __maybe_unused,
as well as a bunch of ifdef checking CONFIG_PM.

This is safe to do because the compiler drops the unused functions,
verified by checking for any of the power management function symbols
being present in System.map for a build without CONFIG_PM.

If a driver has runtime PM, define the ops with pm_ptr(), and if the
driver has Simple PM, use pm_sleep_ptr(), as well as the new versions of
the macros for declaring the members of the pm_ops structs.

Checked with network-enabled allnoconfig, allyesconfig, allmodconfig on

e1000e: Use PME poll to circumvent unreliable ACPI wake

On some I219 devices, ethernet cable plugging detection only works once
from PCI D3 state. Subsequent cable plugging does set PME bit correctly,
but device still doesn't get woken up.

Since I219 connects to the root complex directly, it relies on platform
firmware (ACPI) to wake it up. In this case, the GPE from _PRW only
works for first cable plugging but fails to notify the driver for
subsequent plugging events.

The issue was originally found on CNP, but the same issue can be found
on ADL too. So workaround the issue by continuing use PME poll after
first ACPI wake. As PME poll is always used, the runtime suspend
restriction for CNP can also be removed.

e1000e: Remove redundant pci_enable_pcie_error_reporting()

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this doesn't control interrupt generation by the Root Port; that
is controlled by the AER Root Error Command register, which is managed by
the AER service driver.

e1000e: Fix TX dispatch condition

e1000_xmit_frame is expected to stop the queue and dispatch frames to
hardware if there is not sufficient space for the next frame in the
buffer, but sometimes it failed to do so because the estimated maximum
size of frame was wrong. As the consequence, the later invocation of
e1000_xmit_frame failed with NETDEV_TX_BUSY, and the frame in the buffer
remained forever, resulting in a watchdog failure.

This change fixes the estimated size by making it match with the
condition for NETDEV_TX_BUSY. Apparently, the old estimation failed to
account for the following lines which determines the space requirement
for not causing NETDEV_TX_BUSY:
```
/* reserve a descriptor for the offload context */
if ((mss) || (skb->ip_summed == CHECKSUM_PARTIAL))
count++;
count++;

count += DIV_ROUND_UP(len, adapter->tx_fifo_limit);
```

This issue was found when running http-stress02 test included in Linux
Test Project 20220930 on QEMU with the following commandline:
```
qemu-system-x86_64 -M q35,accel=kvm -m 8G -smp 8
-drive if=virtio,format=raw,file=root.img,file.locking=on
-device e1000e,netdev=netdev
-netdev tap,script=ifup,downscript=no,id=netdev
```

e1000e: Remove unnecessary use of kmap_atomic()

alloc_rx_buf() allocates ps_page->page and buffer_info->page using either
GFP_ATOMIC or GFP_KERNEL. Memory allocated with GFP_KERNEL/GFP_ATOMIC can't
come from highmem and so there's no need to kmap() them. Just use
page_address().

I don't have access to a 32-bit system so did some limited testing on qemu
(qemu-system-i386 -m 4096 -smp 4 -device e1000e) with a 32-bit Debian 11.04
image.

e1000e: Add e1000e trace module

Add tracepoints to the driver via a new file e1000e_trace.h and some new
trace calls added in interesting places in the driver. Add some tracing
for s0ix flows to help in a debug of shared resources with the CSME
firmware. The idea here is that tracepoints have such low performance cost
when disabled that we can leave these in the upstream driver.

Performance not affected, and this can be very useful for debugging and
adding new trace events to paths in the future.

Usage:
echo "e1000e_trace:*" > /sys/kernel/debug/tracing/set_event
echo 1 > /sys/kernel/debug/tracing/events/e1000e_trace/enable
