Commit d1cbfd771c ("ptp_clock: Allow for it to be optional") changed
all PTP-capable Ethernet drivers from `select PTP_1588_CLOCK` to `imply
PTP_1588_CLOCK`, "in order to break the hard dependency between the PTP
clock subsystem and ethernet drivers capable of being clock providers."
As a result it is possible to build PTP-capable Ethernet drivers without
the PTP subsystem by deselecting PTP_1588_CLOCK. Drivers are required to
handle the missing dependency gracefully.
Some PTP-capable Ethernet drivers (e.g., TI_CPSW) factor their PTP code
out into separate drivers (e.g., TI_CPTS_MOD). The above commit also
changed these PTP-specific drivers to `imply PTP_1588_CLOCK`, making it
possible to build them without the PTP subsystem. But as Grygorii
Strashko noted in [1]:

In my view, enabling a PTP-specific driver without the PTP subsystem is
a configuration error made possible by the above commit. Kconfig should
not allow users to create a configuration with missing dependencies that
results in "completely nonfunctional" drivers.
I audited all network drivers that call ptp_clock_register() but merely
`imply PTP_1588_CLOCK` and found five PTP-specific drivers that are
likely nonfunctional without PTP_1588_CLOCK:
NET_DSA_MV88E6XXX_PTP
NET_DSA_SJA1105_PTP
MACB_USE_HWSTAMP
CAVIUM_PTP
TI_CPTS_MOD
Note how these symbols all reference PTP or timestamping in their name;
this is a clue that they depend on PTP_1588_CLOCK.
Change them from `imply PTP_1588_CLOCK` [2] to `depends on PTP_1588_CLOCK`.
I'm not using `select PTP_1588_CLOCK` here because PTP_1588_CLOCK has
its own dependencies, which `select` would not transitively apply.
Additionally, remove the `select NET_PTP_CLASSIFY` from CPTS_TI_MOD;
PTP_1588_CLOCK already selects that.

[2]: NET_DSA_SJA1105_PTP had never declared any type of dependency on
PTP_1588_CLOCK (`imply` or otherwise); adding a `depends on PTP_1588_CLOCK`
here seems appropriate.

MACsec decryption always occurs in a softirq context. Since
the FPU may not be usable in the softirq context, the call to
decrypt may be scheduled on the cryptd work queue. The cryptd
work queue does not provide ordering guarantees. Therefore,
preserving order requires masking out ASYNC implementations
of gcm(aes).
For instance, an Intel CPU with AES-NI makes available the
generic-gcm-aesni driver from the aesni_intel module to
implement gcm(aes). However, this implementation requires
the FPU, so it is not always available to use from a softirq
context, and will fallback to the cryptd work queue, which
does not preserve frame ordering. With this change, such a
system would select gcm_base(ctr(aes-aesni),ghash-generic).
While the aes-aesni implementation prefers to use the FPU, it
will fallback to the aes-asm implementation if unavailable.
By using a synchronous version of gcm(aes), the decryption
will complete before returning from crypto_aead_decrypt().
Therefore, the macsec_decrypt_done() callback will be called
before returning from macsec_decrypt(). Thus, the order of
calls to macsec_post_decrypt() for the frames is preserved.
While it's presumable that the pure AES-NI version of gcm(aes)
is more performant, the hybrid solution is capable of gigabit
speeds on modest hardware. Regardless, preserving the order
of frames is paramount for many network protocols (e.g.,
triggering TCP retries). Within the MACsec driver itself, the
replay protection is tripped by the out-of-order frames, and
can cause frames to be dropped.
This bug has been present in this code since it was added in
v4.6, however it may not have been noticed since not all CPUs
have FPU offload available. Additionally, the bug manifests
as occasional out-of-order packets that are easily
misattributed to other network phenomena.
When this code was added in v4.6, the crypto/gcm.c code did
not restrict selection of the ghash function based on the
ASYNC flag. For instance, x86 CPUs with PCLMULQDQ would
select the ghash-clmulni driver instead of ghash-generic,
which submits to the cryptd work queue if the FPU is busy.
However, this bug was was corrected in v4.8 by commit
b30bdfa864, and was backported
all the way back to the v3.14 stable branch, so this patch
should be applicable back to the v4.6 stable branch.

In ipa_endpoint_stop(), for TX endpoints we set the number of retries

Fix this by using a non-zero retry count for both RX and TX
channels, and just break out of the loop after calling
gsi_channel_stop() for TX channels. This way only RX channels
will retry, and the retry count will be non-zero at the end
for TX channels (so the proper value gets returned).

During MTU change, the following events may happen.
Client-driven CRQ initialization fails due to partner’s CRQ closed,
causing client to enqueue a reset task for FATAL_ERROR. Then passive
(server-driven) CRQ initialization succeeds, causing client to
release CRQ and enqueue a reset task for failover. If the passive
CRQ initialization occurs before the FATAL reset task is processed,
the FATAL error reset task would try to access a CRQ message queue
that was freed, causing an oops. The problem may be most likely to
occur during DLPAR add vNIC with a non-default MTU, because the DLPAR
process will automatically issue a change MTU request.

initialized after client-driven CRQ initialization fails.

The driver is designed to drop Rx packets and reclaim the buffers
when an allocation fails, and the network interface needs to safely
handle this packet loss. Therefore, an allocation failure of Rx
SKBs is relatively benign.
However, the output of the warning message occurs with a high
scheduling priority that can cause excessive jitter/latency for
other high priority processing.
This commit suppresses the warning messages to prevent scheduling
problems while retaining the failure count in the statistics of
the network interface.

When a macsec interface is created, the mtu is calculated with the lower
interface's mtu value.
If the mtu of lower interface is lower than the length, which is needed
by macsec interface, macsec's mtu value will be overflowed.
So, if the lower interface's mtu is too low, macsec interface's mtu
should be set to 0.
Test commands:
ip link add dummy0 mtu 10 type dummy
ip link add macsec0 link dummy0 type macsec
ip link show macsec0
Before:
11: macsec0@dummy0: <BROADCAST,MULTICAST,M-DOWN> mtu 4294967274
After:
11: macsec0@dummy0: <BROADCAST,MULTICAST,M-DOWN> mtu 0

When fixing the initialization race, we neglected to account for
the fact that debugfs is initialized in wiphy_register(), and
some debugfs things went missing (or rather were rerooted to the
global debugfs root).
Fix this by adding debugfs entries only after wiphy_register().
This requires some changes in the rate control code since it
currently adds debugfs at alloc time, which can no longer be
done after the reordering.

The change to track net_device_stats per ring to better support SMP
missed updating the rx_dropped member.
The ndo_get_stats method is also needed to combine the results for

Evidently, at some point in the pre-githistorious past,
drivers/net/ethernet/sgi/meth.h somehow contained some code from the
"snull" driver from the Linux Device Drivers book. A comment crediting
that source, asserting copyright ownership by the LDD authors, and imposing
the LDD2 license terms was duly added to the file.
Any code that may have been derived from snull is long gone, and the
distribution terms are not GPL-compatible. Since the copyright claim is
not based in fact (if it ever was), simply remove it and the distribution
terms as well.
