Some interface types could be nested.
(VLAN, BONDING, TEAM, MACSEC, MACVLAN, IPVLAN, VIRT_WIFI, VXLAN, etc..)
These interface types should set lockdep class because, without lockdep
class key, lockdep always warn about unexisting circular locking.
In the current code, these interfaces have their own lockdep class keys and
these manage itself. So that there are so many duplicate code around the
/driver/net and /net/.
This patch adds new generic lockdep keys and some helper functions for it.
This patch does below changes.
a) Add lockdep class keys in struct net_device
- qdisc_running, xmit, addr_list, qdisc_busylock
- these keys are used as dynamic lockdep key.
b) When net_device is being allocated, lockdep keys are registered.
- alloc_netdev_mqs()
c) When net_device is being free'd llockdep keys are unregistered.
- free_netdev()
d) Add generic lockdep key helper function
- netdev_register_lockdep_key()
- netdev_unregister_lockdep_key()
- netdev_update_lockdep_key()
e) Remove unnecessary generic lockdep macro and functions
f) Remove unnecessary lockdep code of each interfaces.
After this patch, each interface modules don't need to maintain
their lockdep keys.

The LAN8740, like the 8720, also requires a reset after enabling clock.
The datasheet [1] 3.8.5.1 says:
"During a Hardware reset, an external clock must be supplied
to the XTAL1/CLKIN signal."
I have observed this issue on a custom i.MX6 based board with
the LAN8740A.

When firmware indicates that driver needs to invoke firmware reset
which is common for both error recovery and live firmware reset path,
driver needs a different time to wait before polling for firmware
readiness.
Modify the wait time to fw_reset_min_dsecs, which is initialised to
correct timeout for error recovery and firmware reset.

The current code that rounds up the NVRAM parameter bit size to the next
byte size for the devlink parameter is not always correct. The MSIX
devlink parameters are 4 bytes and we don't get the correct size
using this method.
Fix it by adding a new dl_num_bytes member to the bnxt_dl_nvm_param
structure which statically provides bytesize information according
to the devlink parameter type definition.

The tx_clk, rx_clk, and tsu_clk are optional. Currently the macb driver
marks clock as not available if it receives an error when trying to get
a clock. This is wrong, because a clock controller might return
-EPROBE_DEFER if a clock is not available, but will eventually become
available.
In these cases, the driver would probe successfully but will never be
able to adjust the clocks, because the clocks were not available during
probe, but became available later.
For example, the clock controller for the ZynqMP is implemented in the
PMU firmware and the clocks are only available after the firmware driver
has been probed.
Use devm_clk_get_optional() in instead of devm_clk_get() to get the
optional clock and propagate all errors to the calling function.

Uninitialized memmaps contain garbage and in the worst case trigger kernel
BUGs, especially with CONFIG_PAGE_POISONING. They should not get touched.
Right now, when trying to soft-offline a PFN that resides on a memory
block that was never onlined, one gets a misleading error with
CONFIG_PAGE_POISONING:
:/# echo 5637144576 > /sys/devices/system/memory/soft_offline_page
[ 23.097167] soft offline: 0x150000 page already poisoned
But the actual result depends on the garbage in the memmap.
soft_offline_page() can only work with online pages, it returns -EIO in
case of ZONE_DEVICE. Make sure to only forward pages that are online
(iow, managed by the buddy) and, therefore, have an initialized memmap.
Add a check against pfn_to_online_page() and similarly return -EIO.

Once the kTLS TX resync function is called, it used to return
a binary value, for success or failure.
However, in case the TLS SKB is a retransmission of the connection
handshake, it initiates the resync flow (as the tcp seq check holds),
while regular packet handle is expected.
In this patch, we identify this case and skip the resync operation
accordingly.
Counters:
- Add a counter (tls_skip_no_sync_data) to monitor this.
- Bump the dump counters up as they are used more frequently.
- Add a missing counter descriptor declaration for tls_resync_bytes
in sq_stats_desc.

Not all fields of WQE info are being written in the function,
having some leftovers from previous rounds.
Zero-memset it upon update.
Particularly, not nullifying the wi->resync_dump_frag field

As soon as the netdev is registers, the kernel can start using the
interface. If the driver connects the MAC to the PHY after the netdev
is registered, there is a race condition where the interface can be
opened without having the PHY connected.
Change the order to close this race condition.

devlink maintains packets and bytes statistics for each trap. Since
eth_type_trans() was called to set the skb's protocol, the data pointer
no longer points to the start of the packet and the bytes accounting is
off by 14 bytes.
Fix this by pushing the skb's data pointer to the start of the packet.

The EPHY integrated into the 40nm Set-Top Box devices can falsely
detect energy when connected to a disabled peer interface. When the
peer interface is enabled the EPHY will detect and report the link
as active, but on occasion may get into a state where it is not
able to exchange data with the connected GENET MAC. This issue has
not been observed when the link parameters are auto-negotiated;
however, it has been observed with a manually configured link.
It has been empirically determined that issuing a soft reset to the
EPHY when energy is detected prevents it from getting into this bad
state.

It turns out that the "Workaround for putting the PHY in IDDQ mode"
used by the internal EPHYs on 40nm Set-Top Box chips when powering
down puts the interface to the GENET MAC in a state that can cause
subsequent MAC resets to be incomplete.
Rather than restore the forced soft reset when powering up internal
PHYs, this commit moves the invocation of phy_init_hw earlier in
the MAC initialization sequence to just before the MAC reset in the
open and resume functions. This allows the interface to be stable
and allows the MAC resets to be successful.
The bcmgenet_mii_probe() function is split in two to accommodate
this. The new function bcmgenet_mii_connect() handles the first
half of the functionality before the MAC initialization, and the
bcmgenet_mii_config() function is extended to provide the remaining
PHY configuration following the MAC initialization.

The internal 40nm EPHYs use a "Workaround for putting the PHY in
IDDQ mode." These PHYs require a soft reset to restore functionality
after they are powered back up.
This commit defines the soft_reset function to use genphy_soft_reset
during phy_init_hw to accommodate this.

When commit 28b2e0d2cd13 ("net: phy: remove parameter new_link from
phy_mac_interrupt()") removed the new_link parameter it set the
phydev->link state from the MAC before invoking phy_mac_interrupt().
However, once commit 88d6272acaaa ("net: phy: avoid unneeded MDIO
reads in genphy_read_status") was added this initialization prevents
the proper determination of the connection parameters by the function
genphy_read_status().
This commit removes that initialization to restore the proper
functionality.
