We call pci_set_drvdata immediately after calling register_netdev,
which leaves a window where tasks writing to the sriov_numvfs sysfs
attribute can sneak in and crash the kernel. register_netdev cleans
up after itself so placing pci_set_drvdata immediately before it
should preserve the intent of commit 0fb6a55cc31f ("ixgbe: fix crash
on rmmod after probe fail").

The ixgbe driver has logic to handle only one Tx timestamp at a time,
using a state bit lock to avoid multiple requests at once.
It may be possible, if incredibly unlikely, that a Tx timestamp event is
requested but never completes. Since we use an interrupt scheme to
determine when the Tx timestamp occurred we would never clear the state
bit in this case.
Add an ixgbe_ptp_tx_hang() function similar to the already existing
ixgbe_ptp_rx_hang() function. This function runs in the watchdog routine
and makes sure we eventually recover from this case instead of
permanently disabling Tx timestamps.
Note: there is no currently known way to cause this without hacking the
driver code to force it.

The ixgbe driver can only handle one Tx timestamp request at a time.
This means it is possible for an application timestamp request to be
ignored.
There is no easy way for an administrator to determine if this occurred.

The ixgbe driver uses a state bit lock to avoid handling more than one Tx
timestamp request at once. This is required because hardware is limited
to a single set of registers for Tx timestamps.
The state bit lock is not properly cleaned up during
ixgbe_xmit_frame_ring() if the transmit fails such as due to DMA or TSO
failure. In some hardware this results in blocking timestamps until the
service task times out. In other hardware this results in a permanent
lock of the timestamp bit because we never receive an interrupt
indicating the timestamp occurred, since indeed the packet was never
transmitted.
Fix this by checking for DMA and TSO errors in ixgbe_xmit_frame_ring() and
properly cleaning up after ourselves when these occur.

Hardware related to the ixgbe driver is limited to handling a single Tx
timestamp request at a time. Thus, the driver ignores requests for Tx
timestamp while waiting for the current request to finish. It uses
a state bit lock which enforces that only one timestamp request is
honored at a time.
Unfortunately this suffers from a simple race condition. The bit lock is
not cleared until after skb_tstamp_tx() is called notifying applications
of a new Tx timestamp. Even a well behaved application sending only one
packet at a time and waiting for a response can wake up and send a new
packet before the bit lock is cleared. This results in needlessly
dropping some Tx timestamp requests.
We can fix this by unlocking the state bit as soon as we read the
Timestamp register, as this is the first point at which it is safe to
unlock.
To avoid issues with the skb pointer, we'll use a copy of the pointer
and set the global variable in the driver structure to NULL first. This
ensures that the next timestamp request does not modify our local copy
of the skb pointer.
This ensures that well behaved applications do not accidentally race
with the unlock bit. Obviously an application which sends multiple Tx
timestamp requests at once will still only timestamp one packet at
a time. Unfortunately there is nothing we can do about this.

====================
net: dsa: Multi-CPU ground work (v4)
This patch series prepares the ground for adding mutliple CPU port support to
DSA, and starts by removing redundant pieces of information such as
master_netdev which is cpu_dp->ethernet. Finally drivers are moved away from
directly accessing ds->dst->cpu_dp and use appropriate helper functions.
Note that if you have Device Tree blobs/platform configurations that are
currently listing multiple CPU ports, the proposed behavior in
dsa_ds_get_cpu_dp() will be to return the last bit set in ds->cpu_port_mask.
Future plans include:
- making dst->cpu_dp a flexible data structure (array, list, you name it)
- having the ability for drivers to return a default/preferred CPU port (if
necessary)
Changes in v4:
- fixed build warning with NETPOLL enabled
Changes in v3:
- removed the last patch since it causes problems with bcm_sf2/b53 in a
dual-CPU case (root cause known, proper fix underway)
- removed dsa_ds_get_cpu_dp()
Changes in v2:
- added Reviewed-by tags
- assign port->cpu_dp earlier before ops->setup() has run

In preparation for supporting multiple CPU ports, remove
dst->master_netdev and ds->master_netdev and replace them with only one
instance of the common object we have for a port: struct
dsa_port::netdev. ds->master_netdev is currently write only and would be
helpful in the case where we have two switches, both with CPU ports, and
also connected within each other, which the multi-CPU port patch series
would address.
While at it, introduce a helper function used in net/dsa/slave.c to
immediately get a reference on the master network device called
dsa_master_netdev().

Verify that the caller-provided sockaddr structure is large enough to
contain the sa_family field, before accessing it in the connect()
handler of the AF_CAIF socket. Since the syscall doesn't enforce a minimum
size of the corresponding memory region, very short sockaddrs (zero or one

The of_mdio_parse_addr() helper function is useful to other code, but

The selftests depend on using the shell exit code as a mean of
detecting the success or failure of test-binary executed. The
appropiate output "[PASS]" or "[FAIL]" in generated by
tools/testing/selftests/lib.mk.
Notice that the exit code is masked with 255. Thus, be careful if
using the number of errors as the exit code, as 256 errors would be
seen as a success.
There are two standard defined exit(3) codes:
/usr/include/stdlib.h
#define EXIT_FAILURE 1 /* Failing exit status. */
#define EXIT_SUCCESS 0 /* Successful exit status. */
Fix test_verifier.c to not use the negative value of variable
"results", but instead return EXIT_FAILURE.

The IBM vNIC protocol provides support for the user to initiate
a failover from the client LPAR in case the current backing infrastructure
is deemed inadequate or in an error state.
Support for two H_VIOCTL sub-commands for vNIC devices are required
to implement this function. These commands are H_GET_SESSION_TOKEN
and H_SESSION_ERR_DETECTED.
"[H_GET_SESSION_TOKEN] is used to obtain a session token from a VNIC client
adapter. This token is opaque to the caller and is intended to be used in
tandem with the SESSION_ERROR_DETECTED vioctl subfunction."
"[H_SESSION_ERR_DETECTED] is used to report that the currently active
backing device for a VNIC client adapter is behaving poorly, and that
the hypervisor should attempt to fail over to a different backing device,
if one is available."
To provide tools access to this functionality the vNIC driver creates a
sysfs file that, when written to, will send a request to pHyp to failover
to a different backing device.

For implicit namespacing and clarity, prefix the common Port Jamming

differ between implementations with a chosen reference model
(e.g. MV88E6097_PORT_JAM_CTL.)
The 88E6390 family renamed the register to Flow Control and turned it
