Fix a small slab info leak due to a failure to clear the command buffer
at allocation.
The first 16 bytes of the command buffer are always sent to the device
in pcan_usb_send_cmd() even though only the first two may have been
initialised in case no argument payload is provided (e.g. when waiting
for a response).

When decoding a buffer received from PCAN-USB, the first timestamp read in
a packet is a 16-bit coded time base, and the next ones are an 8-bit
offset to this base, regardless of the type of packet read.
This patch corrects a potential loss of synchronization by using a
timestamp index read from the buffer, rather than an index of received
data packets, to determine on the sizeof the timestamp to be read from the
packet being decoded.

The ECC (memory error detection and correction) mechanism can be
activated or not, controlled by the ECCDIS bit in CAN_MECR. When
disabled, updates on indications and reporting registers are stopped.
So if want to disable ECC completely, had better assert ECCDIS bit, not

Add zero copy AF_XDP support. This patch adds zero copy support for
Tx and Rx; code for zero copy is added to ice_xsk.h and ice_xsk.c.
For Tx, implement ndo_xsk_wakeup. As with other drivers, reuse
existing XDP Tx queues for this task, since XDP_REDIRECT guarantees
mutual exclusion between different NAPI contexts based on CPU ID. In
turn, a netdev can XDP_REDIRECT to another netdev with a different
NAPI context, since the operation is bound to a specific core and each
core has its own hardware ring.
For Rx, allocate frames as MEM_TYPE_ZERO_COPY on queues that AF_XDP is
enabled.

Before this change of_get_phy_mode() returned an enum,
phy_interface_t. On error, -ENODEV etc, is returned. If the result of
the function is stored in a variable of type phy_interface_t, and the
compiler has decided to represent this as an unsigned int, comparision
with -ENODEV etc, is a signed vs unsigned comparision.
Fix this problem by changing the API. Make the function return an
error, or 0 on success, and pass a pointer, of type phy_interface_t,
where the phy mode should be stored.
v2:
Return with *interface set to PHY_INTERFACE_MODE_NA on error.

As reported in [0] at least one RTL8168dp version has problems
establishing a link. This chip version has an integrated RTL8211b PHY,
however the chip seems to report a wrong PHY ID, resulting in a wrong
PHY driver (for Generic Realtek PHY) being loaded.
Work around this issue by adding a hook to r8168dp_2_mdio_read()
for returning the correct PHY ID.

During connection tracking offloads with high number of connections,
(40K connections per second), flow table group lock contention is
observed.
To improve the performance by reducing lock contention, lockless
FTE read lookup is performed as described below.
Each flow table entry is refcounted.
Flow table entry is removed when refcount drops to zero.
rhash table allows rcu protected lookup.
Each hash table entry insertion and removal is write lock protected.
Hence, it is possible to perform lockless lookup in rhash table using
following scheme.
(a) Guard FTE entry lookup per group using rcu read lock.
(b) Before freeing the FTE entry, wait for all readers to finish
accessing the FTE.
Below example of one reader and write in parallel racing, shows
protection in effect with rcu lock.

Intel Wired LAN Driver Updates 2019-11-01
This series contains updates to e1000, igb, igc, ixgbe, i40e and driver
documentation.
Lyude Paul fixes an issue where a fatal read error occurs when the
device is unplugged from the machine. So change the read error into a
warn while the device is still present.
Manfred Rudigier found that the i350 device was not apart of the "Media
Auto Sense" feature, yet the device supports it. So add the missing
i350 device to the check and fix an issue where the media auto sense
would flip/flop when no cable was connected to the port causing spurious
kernel log messages.
I fixed an issue where the fix to resolve receive buffer starvation was
applied in more than one place in the driver, one being the incorrect
location in the i40e driver.
Wenwen Wang fixes a potential memory leak in e1000 where allocated
memory is not properly cleaned up in one of the error paths.
Jonathan Neuschäfer cleans up the driver documentation to be consistent
and remove the footnote reference, since the footnote no longer exists in
the documentation.

Currently on ECPF, metadata is enabled on the ECPF vport = 0xfffe
(manager vport).
Metadata when supported, must be enabled on own vport which is
used to pass metadata to vport of NIC Rx Flow Table.
Due to this error, traffic tagged by ingress ACL is not processed
correctly at NIC rx flow table level which is supposed to work
on metadata tag.
Hence, instead of working on eswitch manager vport, always working on
eswitch own vport regardless of PF or ECPF.
Given that mlx5_eswitch_query/modify_esw_vport_context() is used to
access other vport in legacy mode and own vport settings in switchdev mode,
extend low level API to explicitly specify other_vport.

Currently legacy mode enables ACL while enabling vport, while offloads
mode enable ACL when moving to offloads mode.

enabling/disabling a vport.
It also eliminates creating ingress ACL table on unused ECPF vport in
offloads mode.

drop rule ACLs are created/destroyed, so that ACL configuration is self
contained for ingress and egress.
