3b25528e1e net: stmmac: dwmac-rk: Don't fail if phy regulator is absent
The devicetree binding lists the phy phy as optional. As such, the
driver should not bail out if it can't find a regulator. Instead it
should just skip the remaining regulator related code and continue
on normally.

Skip the remainder of phy_power_on() if a regulator supply isn't
available. This also gets rid of the bogus return code.

b9500577d3 iwlwifi: pcie: handle switching killer Qu B0 NICs to C0
We need to use a different firmware for C0 versions of killer Qu NICs.
Add structures for them and handle them in the if block that detects
C0 revisions.

Additionally, instead of having an inclusive check for QnJ devices,
make the selection exclusive, so that switching to QnJ is the
exception, not the default.  This prevents us from having to add all
the non-QnJ cards to an exclusion list.  To do so, only go into the
QnJ block if the device has an RF ID type HR and HW revision QnJ.

e8024cb483 nfp: flower: handle neighbour events on internal ports
Recent code changes to NFP allowed the offload of neighbour entries to FW
when the next hop device was an internal port. This allows for offload of
tunnel encap when the end-point IP address is applied to such a port.

Unfortunately, the neighbour event handler still rejects events that are
not associated with a repr dev and so the firmware neighbour table may get
out of sync for internal ports.

Fix this by allowing internal port neighbour events to be correctly
processed.

739d7c5752 nfp: flower: prevent ingress block binds on internal ports
Internal port TC offload is implemented through user-space applications
(such as OvS) by adding filters at egress via TC clsact qdiscs. Indirect
block offload support in the NFP driver accepts both ingress qdisc binds
and egress binds if the device is an internal port. However, clsact sends
bind notification for both ingress and egress block binds which can lead
to the driver registering multiple callbacks and receiving multiple
notifications of new filters.

Fix this by rejecting ingress block bind callbacks when the port is
internal and only adding filter callbacks for egress binds.

49d4b14113 Revert "r8152: napi hangup fix after disconnect"
This reverts commit 0ee1f47349.

The commit 0ee1f47349 ("r8152: napi hangup fix after
disconnect") adds a check about RTL8152_UNPLUG to determine
if calling napi_disable() is invalid in rtl8152_close(),
when rtl8152_disconnect() is called. This avoids to use
napi_disable() after calling netif_napi_del().

Howver, commit ffa9fec30c ("r8152: set RTL8152_UNPLUG
only for real disconnection") causes that RTL8152_UNPLUG
is not always set when calling rtl8152_disconnect().
Therefore, I have to revert commit 0ee1f47349 ("r8152:

another patch to fix it.

36f1031c51 ibmvnic: Do not process reset during or after device removal
Currently, the ibmvnic driver will not schedule device resets
if the device is being removed, but does not check the device
state before the reset is actually processed. This leads to a race
where a reset is scheduled with a valid device state but is
processed after the driver has been removed, resulting in an oops.

Fix this by checking the device state before processing a queued
reset event.

94acaeb50c Add genphy_c45_config_aneg() function to phy-c45.c
Commit 34786005ec ("net: phy: prevent PHYs w/o Clause 22 regs from calling
genphy_config_aneg") introduced a check that aborts phy_config_aneg()
if the phy is a C45 phy.
This causes phy_state_machine() to call phy_error() so that the phy
ends up in PHY_HALTED state.

Instead of returning -EOPNOTSUPP, call genphy_c45_config_aneg()
(analogous to the C22 case) so that the state machine can run
correctly.

genphy_c45_config_aneg() closely resembles mv3310_config_aneg()
in drivers/net/phy/marvell10g.c, excluding vendor specific
configurations for 1000BaseT.

86c28b2d69 nfp: bpf: fix latency bug when updating stack index register
NFP is using Local Memory to model stack. LM_addr could be used as base of
a 16 32-bit word region of Local Memory. Then, if the stack offset is
beyond the current region, the local index needs to be updated. The update
needs at least three cycles to take effect, therefore the sequence normally
looks like:

  local_csr_wr[ActLMAddr3, gprB_5]
  nop
  nop
  nop

If the local index switch happens on a narrow loads, then the instruction
preparing value to zero high 32-bit of the destination register could be
counted as one cycle, the sequence then could be something like:

  local_csr_wr[ActLMAddr3, gprB_5]
  nop
  nop
  immed[gprB_5, 0]

However, we have zero extension optimization that zeroing high 32-bit could
be eliminated, therefore above IMMED insn won't be available for which case
the first sequence needs to be generated.

f53a7ad189 r8152: Set memory to all 0xFFs on failed reg reads
get_registers() blindly copies the memory written to by the
usb_control_msg() call even if the underlying urb failed.

This could lead to junk register values being read by the driver, since
some indirect callers of get_registers() ignore the return values. One
example is:
  ocp_read_dword() ignores the return value of generic_ocp_read(), which
  calls get_registers().

So, emulate PCI "Master Abort" behavior by setting the buffer to all
0xFFs when usb_control_msg() fails.

This patch is copied from the r8152 driver (v2.12.0) published by
Realtek (www.realtek.com).

That can cause a long delay in fw fatal error handling which waits in a

try asking for fw core dump command while fw in fatal state may not
respond and driver will wait for command timeout.

50f5604476 iwlwifi: mvm: Allow multicast data frames only when associated
The MAC context configuration always allowed multicast data frames
to pass to the driver for all MAC context types, and in the
case of station MAC context both when associated and when not
associated.

One of the outcomes of this configuration is having the FW forward
encrypted multicast frames to the driver with Rx status indicating
that the frame was not decrypted (as expected, since no keys were
configured yet) which in turn results with unnecessary error
messages.

9584412438 rt2x00: clear IV's on start to fix AP mode regression
To do not brake HW restart we should keep initialization vectors data.
I assumed that on start the data is already initialized to zeros, but
that not true on some scenarios and we should clear it. So add
additional flag to check if we are under HW restart and clear IV's
data if we are not.

Patch fixes AP mode regression.

cfef46d692 ravb: Fix use-after-free ravb_tstamp_skb
When a Tx timestamp is requested, a pointer to the skb is stored in the
ravb_tstamp_skb struct. This was done without an skb_get. There exists
the possibility that the skb could be freed by ravb_tx_free (when
ravb_tx_free is called from ravb_start_xmit) before the timestamp was
processed, leading to a use-after-free bug.

Use skb_get when filling a ravb_tstamp_skb struct, and add appropriate
frees/consumes when a ravb_tstamp_skb struct is freed.

Instead unmap it when the hypervisor call has completed. This patch
avoids the possibility that a buffer will not be unmapped because

9bf46566e8 bnxt_en: Fix to include flow direction in L2 key
FW expects the driver to provide unique flow reference handles
for Tx or Rx flows. When a Tx flow and an Rx flow end up sharing
a reference handle, flow offload does not seem to work.
This could happen in the case of 2 flows having their L2 fields
wildcarded but in different direction.
Fix to incorporate the flow direction as part of the L2 key

v2: Move the dir field to the end of the bnxt_tc_l2_key struct to
fix the warning reported by kbuild test robot <lkp@intel.com>.
There is existing code that initializes the structure using
nested initializer and will warn with the new u8 field added to
the beginning.  The structure also packs nicer when this new u8 is
added to the end of the structure [MChan].

685ec6a81b bnxt_en: Use correct src_fid to determine direction of the flow
Direction of the flow is determined using src_fid. For an RX flow,
src_fid is PF's fid and for TX flow, src_fid is VF's fid. Direction
of the flow must be specified, when getting statistics for that flow.
Currently, for DECAP flow, direction is determined incorrectly, i.e.,
direction is initialized as TX for DECAP flow, instead of RX. Because
of which, stats are not reported for this DECAP flow, though it is
offloaded and there is traffic for that flow, resulting in flow age out.

This patch fixes the problem by determining the DECAP flow's direction
using correct fid.  Set the flow direction in all cases for consistency
even if 64-bit flow handle is not used.

e8f267b063 bnxt_en: Improve RX doorbell sequence.
When both RX buffers and RX aggregation buffers have to be
replenished at the end of NAPI, post the RX aggregation buffers first
before RX buffers.  Otherwise, we may run into a situation where
there are only RX buffers without RX aggregation buffers for a split
second.  This will cause the hardware to abort the RX packet and
report buffer errors, which will cause unnecessary cleanup by the
driver.

Ringing the Aggregation ring doorbell first before the RX ring doorbell
will prevent some of these buffer errors.  Use the same sequence during
ring initialization as well.
