ac7a1717a2 nfp: bpf: complete ALU32 logic shift supports

  BPF_ALU | BPF_LSH | BPF_X
  BPF_ALU | BPF_RSH | BPF_X
  BPF_ALU | BPF_RSH | BPF_K

For BPF_RSH | BPF_K, it could be implemented using NFP direct shift
instruction. For the other BPF_X shifts, NFP indirect shifts sequences need
to be used.

Separate code-gen hook is assigned to each instruction to make the
implementation clear.

db0a4b3b6b nfp: bpf: correct the behavior for shifts by zero
Shifts by zero do nothing, and should be treated as nops.

Even though compiler is not supposed to generate such instructions and
manual written assembly is unlikely to have them, but they are legal
instructions and have defined behavior.

This patch correct existing shifts code-gen to make sure they do nothing
when shift amount is zero except when the instruction is ALU32 for which
high bits need to be cleared.

For shift amount bigger than type size, already, NFP JIT back-end errors
out for immediate shift and only low 5 bits will be taken into account for
indirect shift which is the same as x86.

ee69804714 nfp: use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

instance = kzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

fa6821cbf1 r8169: improve WoL handling
WoL handling for the RTL8168 family is a little bit tricky because of
different types of broken BIOS and/or chip quirks.

Two known issues:
1. Network properly resumes from suspend only if WoL is enabled in the chip.
2. Some notebooks wake up immediately if system is suspended and network
   device is wakeup-enabled.

Few patches tried to deal with this:
7edf6d314c ("r8169: disable WOL per default")
18041b5236 ("r8169: restore previous behavior to accept BIOS WoL
settings")

Currently we have the situation that the chip WoL settings as set by
the BIOS are respected (to prevent issue 1), but the device doesn't get
wakeup-enabled (to prevent issue 2).

This leads to another issue:
If systemd is told to set WoL it first checks whether the requested
settings are active already (and does nothing if yes). Due to the chip
WoL flags being set properly systemd assumes that WoL is configured
properly in our case. Result is that device doesn't get wakeup-enabled
and WoL doesn't work (until it's set e.g. by ethtool).

This patch now:
- leaves the chip WoL settings as is (to prevent issue 1)
- keeps the behavior to not wakeup-enable the device initially
  (to prevent issue 2)
- In addition we report WoL as being disabled in get_wol, matching
  that device isn't wakeup-enabled. If systemd is told to enable WoL,
  it will therefore detect that it has to do something and will
  call set_wol.

Of course the user still has the option to override this with
e.g. ethtool.

v2:
- Don't just exclude __rtl8169_get_wol() from compiling, remove it.
v3:
- adjust commit message

When the VF shares the same TC config as PF, the business

For simplicity, we are not considering VF sharing the same tc
configuration as PF use case, so this patch removes the support
of TC configuration from VF and forcing VF to just use single
TC.

The Mediatek MT7621 SoC contains the same ethernet hardware module as
used on a number of other MediaTek SoC parts. There are some minor
differences to deal with but we can use the same driver to support
them all.

This patch is based on work by Bjørn Mork <bjorn@mork.no>, and his
original patch is at:

3293bc63f5

There is an additional compatible devicetree type added, and the primary
change to the code required is to support a single interrupt (for both
RX and TX interrupts).

782a624d00 bnxt_en: Add bnxt_en initial port params table and register it
Register devlink_port with devlink and create initial port params
table for bnxt_en. The table consists of a generic parameter:

wake_on_lan: Enables Wake on Lan for this port when magic packet
is received with this port's MAC address using ACPI pattern.
If enabled, the controller asserts a wake pin upon reception of
WoL packet.  ACPI (Advanced Configuration and Power Interface) is
an industry specification for the efficient handling of power
consumption in desktop and mobile computers.

v2->v3:
- Modify bnxt_dl_wol_validate(), to throw error message when user gives
  value other than DEVLINK_PARAM_WAKE_MAGIC ot to disable WOL.
- Use netdev_err() instead of netdev_warn(), when devlink_port_register()
  and devlink_port_params_register() returns error. Also, don't log rc
  in this message.

c829f5f52d cxgb4: cxgb4_tc_u32: use struct_size() in kvzalloc()
One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

instance = kvzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:

instance = kvzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

The interrupt handler contains a workaround for RX hang applicable
to Zynq and AT91RM9200 only. Subsequent versions do not need this
workaround. This workaround unnecessarily resets RX whenever RX used
bit read is observed, which can be often under heavy traffic. There
is no other action performed on RX UBR interrupt. Hence introduce a
CAPS mask; enable this interrupt and workaround only on affected
versions.
