bond_xmit_roundrobin() checks for IGMP packets but it parses
the IP header even before checking skb->protocol.
We should validate the IP header with pskb_may_pull() before
using iph->protocol.

r8153b_rx_agg_chg_indicate() needs to be called after enabling TX/RX and
before calling rxdy_gated_en(tp, false). Otherwise, the change of the
settings of RX aggregation wouldn't work.
Besides, adjust rtl8152_set_coalesce() for the same reason. If
rx_coalesce_usecs is changed, restart TX/RX to let the setting work.

Similarly, other callers of idr_get_next_ul() suffer the same
overflow bug as they don't handle it properly either.
Introduce idr_for_each_entry_continue_ul() to help these callers
iterate from a given ID.
cls_flower needs more care here because it still has overflow when
does arg->cookie++, we have to fold its nested loops into one
and remove the arg->cookie++.

__vxlan_dev_create() destroys FDB using specific pointer which indicates
a fdb when error occurs.
But that pointer should not be used when register_netdevice() fails because
register_netdevice() internally destroys fdb when error occurs.
This patch makes vxlan_fdb_create() to do not link fdb entry to vxlan dev
internally.
Instead, a new function vxlan_fdb_insert() is added to link fdb to vxlan
dev.
vxlan_fdb_insert() is called after calling register_netdevice().
This routine can avoid situation that ->ndo_uninit() destroys fdb entry
in error path of register_netdevice().
Hence, error path of __vxlan_dev_create() routine can have an opportunity
to destroy default fdb entry by hand.
Test command
ip link add bonding_masters type vxlan id 0 group 239.1.1.1 \
dev enp0s9 dstport 4789

In an earlier commit to improve NQ reservations on 57500 chips, we
set the resv_irqs on the 57500 VFs to the fixed value assigned by
the PF regardless of how many are actually used. The current
code assumes that resv_irqs minus the ones used by the network driver
must be the ones for the RDMA driver. This is no longer true and
we may return more MSIX vectors than requested, causing inconsistency.
Fix it by capping the value.

The current logic assumes that the RDMA driver uses one statistics
context adjacent to the ones used by the network driver. This
assumption is not true and the statistics context used by the
RDMA driver is tied to its MSIX base vector. This wrong assumption
can cause RDMA driver failure after changing ethtool rings on the
network side. Fix the statistics reservation logic accordingly.

Some chips with older firmware can continue to perform DMA read from
context memory even after the memory has been freed. In the PCI shutdown
method, we need to call pci_disable_device() to shutdown DMA to prevent
this DMA before we put the device into D3hot. DMA memory request in
D3hot state will generate PCI fatal error. Similarly, in the driver
remove method, the context memory should only be freed after DMA has
been shutdown for correctness.

Currently bnx2x ptp worker tries to read a register with timestamp
information in case of TX packet timestamping and in case it fails,
the routine reschedules itself indefinitely. This was reported as a
kworker always at 100% of CPU usage, which was narrowed down to be
bnx2x ptp_task.
By following the ioctl handler, we could narrow down the problem to
an NTP tool (chrony) requesting HW timestamping from bnx2x NIC with
RX filter zeroed; this isn't reproducible for example with ptp4l
(from linuxptp) since this tool requests a supported RX filter.
It seems NIC FW timestamp mechanism cannot work well with
RX_FILTER_NONE - driver's PTP filter init routine skips a register
write to the adapter if there's not a supported filter request.
This patch addresses the problem of bnx2x ptp thread's everlasting
reschedule by retrying the register read 10 times; between the read
attempts the thread sleeps for an increasing amount of time starting
in 1ms to give FW some time to perform the timestamping. If it still
fails after all retries, we bail out in order to prevent an unbound
resource consumption from bnx2x.
The patch also adds an ethtool statistic for accounting the skipped
TX timestamp packets and it reduces the priority of timestamping
error messages to prevent log flooding. The code was tested using
both linuxptp and chrony.

The Header Parser allows identifying various fields in the packet
headers, used for various kind of filtering and classification
steps.
This is a re-entrant process, where the offset in the packet header
depends on the previous lookup results. This offset is represented in
the SRAM results of the TCAM, as a shift to be operated.
This shift can be negative in some cases, such as in IPv6 parsing.
This commit prevents overriding the sign bit when setting the shift
value, which could cause instabilities when parsing IPv6 flows.

A b53 device may configured through an external EEPROM like the switch
device on the Lamobo R1 router board. The configuration of a port may
therefore differ from the reset configuration of the switch.
The switch configuration reported by the DSA subsystem is different until
the port is configured by DSA i.e. a port can be active, while the DSA
subsystem reports the port is inactive. Disable all ports and not only
the unused ones to put all ports into a well defined state.

for rx") breaks A-MSDU support. When A-MSDU is enable the device can
receive frames up to q->buf_size but they will be discarded in
mt76u_process_rx_entry since there is no enough room for
skb_shared_info. Fix the issue reallocating the skb and copying in the
linear area the first 128B of the received frames and in the frag_list
the remaining part

Replace gpiod_set_value() with gpiod_set_value_cansleep(), as the switch
reset GPIO can be connected to e.g. I2C GPIO expander and it is perfectly
fine for the kernel to sleep for a bit in ksz_switch_register().

In configuration of vlan over bridge over aquantia device
it was found that vlan tagged traffic is dropped on chip.
The reason is that bridge device enables promisc mode,
but in atlantic chip vlan filters will still apply.
So we have to corellate promisc settings with vlan configuration.
The solution is to track in a separate state variable the
need of vlan forced promisc. And also consider generic
promisc configuration when doing vlan filter config.

We build vlan on top of bonding interface, which vlan offload
is off, bond mode is 802.3ad (LACP) and xmit_hash_policy is
BOND_XMIT_POLICY_ENCAP34.
Because vlan tx offload is off, vlan tci is cleared and skb push
the vlan header in validate_xmit_vlan() while sending from vlan
devices. Then in bond_xmit_hash, __skb_flow_dissect() fails to
get information from protocol headers encapsulated within vlan,
because 'nhoff' is points to IP header, so bond hashing is based
on layer 2 info, which fails to distribute packets across slaves.
This patch always enable bonding's vlan tx offload, pass the vlan
packets to the slave devices with vlan tci, let them to handle
vlan implementation.

Currently, in suspend() and resume(), ishtp client drivers are using
driver_data to get "struct ishtp_cl_device" object which is set by
bus driver. It's wrong since the driver_data should not be owned bus.
driver_data should be owned by the corresponding ishtp client driver.
Due to this, some ishtp client driver like cros_ec_ishtp which uses
its driver_data to transfer its data to its child doesn't work correctly.
So this patch removes setting driver_data in bus drier and instead of
using driver_data to get "struct ishtp_cl_device", since "struct device"
is embedded in "struct ishtp_cl_device", we introduce a helper function
that returns "struct ishtp_cl_device" from "struct device".

The HID++ spec also defines very long HID++ reports, with a reportid of
0x12. The MX5000 and MX5500 keyboards use 0x12 output reports for sending
messages to display on their buildin LCD.
Userspace (libmx5000) supports this, in order for this to work when talking
to the HID devices instantiated for the keyboard by hid-logitech-dj,
we need to properly forward these reports to the device.
This commit fixes logi_dj_ll_raw_request not forwarding these reports.

For the first call to realloc_argv() in dm_split_args(), old_argv is
NULL and size is zero. Then memcpy is called, with the NULL old_argv
as the source argument and a zero size argument. AFAIK, this is
undefined behavior and generates the following warning when compiled
with UBSAN on ppc64le:

Currently, although we submit super bios in order (and super.nr_entries
is incremented by each logged entry), submit_bio() is async so each
super sector may not be written to log device in order and then the
final nr_entries may be smaller than it should be.
This problem can be reproduced by the xfstests generic/455 with ext4:
QA output created by 455
-Silence is golden
+mark 'end' does not exist
Fix this by serializing submission of super sectors to make sure each
is written to the log disk in order.
