Currently, psample can only send the packet bits after decapsulation.
The tunnel information is lost. Add the tunnel support.
If the sampled packet has no tunnel info, the behavior is the same as
before. If it has, add a nested metadata field named PSAMPLE_ATTR_TUNNEL
and include the tunnel subfields if applicable.
Increase the metadata length for sampled packet with the tunnel info.
If new subfields of tunnel info should be included, update the metadata
length accordingly.

1GbE Intel Wired LAN Driver Updates 2020-05-19
This series contains updates to igc only.
Sasha cleans up the igc driver code that is not used or needed.
Vitaly cleans up driver code that was used to support Virtualization on
a device that is not supported by igc, so remove the dead code.
Andre renames a few macros to align with register and field names
described in the data sheet. Also adds the VLAN Priority Queue Fliter
and EType Queue Filter registers to the list of registers dumped by
igc_get_regs(). Added additional debug messages and updated return codes
for unsupported features. Refactored the VLAN priority filtering code to
move the core logic into igc_main.c. Cleaned up duplicate code and
useless code.

uaccess-related stuff in net/*
Assorted uaccess-related work in net/*. First, there's
getting rid of compat_alloc_user_space() mess in MCAST_...
[gs]etsockopt() - no need to play with copying to/from temporary
object on userland stack, etc., when ->compat_[sg]etsockopt()
instances in question can easly do everything without that.

atm_dev_ioctl() does copyin in two different ways - one for
ATM_GETNAMES, another for everything else. Start with separating
the former into a new helper (atm_getnames()). The next step

Native ->setsockopt() handling of these options (MCAST_..._SOURCE_GROUP
and MCAST_{,UN}BLOCK_SOURCE) consists of copyin + call of a helper that
does the actual work. The only change needed for ->compat_setsockopt()
is a slightly different copyin - the helpers can be reused as-is.

Parallel to what the native setsockopt() does, except that unlike
the native setsockopt() we do not use memdup_user() - we want
the sockaddr_storage fields properly aligned, so we allocate
4 bytes more and copy compat_group_filter at the offset 4,
which yields the proper alignments.

now we can do MCAST_MSFILTER in compat ->getsockopt() without
playing silly buggers with copying things back and forth.
We can form a native struct group_filter (sans the variable-length
tail) on stack, pass that + pointer to the tail of original request
to the helper doing the bulk of the work, then do the rest of
copyout - same as the native getsockopt() does.
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
pass the userland pointer to the array in its tail, so that part
gets copied out by our functions; copyout of everything else is
done in the callers. Rationale: reuse for compat; the array
is the same in native and compat, the layout of parts before it
is different for compat.

We want to get rid of compat_mc_[sg]etsockopt() and to have that stuff
handled without compat_alloc_user_space(), extra copying through
userland, etc. To do that we'll need ipv4 and ipv6 instances of
->compat_[sg]etsockopt() to manipulate the 32bit variants of mcast
requests, so we need to move the definitions of those out of net/compat.c
and into a public header.

The whole ethertype filtering code is implemented in igc_ethtool.c and
mixes logic from ethtool and core parts. This patch refactors it so core
logic is moved to igc_main.c, aligning the ethertype filtering code
organization with the rest of the filtering code from the driver (MAC
address and VLAN priority).
Besides moving code to igc_main.c, this patch also does some minor
improvements to the code. Below are some highlights.
In case all filters are already in use and the user tries to add another
filter, we return -ENOSPC instead of -EINVAL so a more meaningful error
code is provided. This also aligns with the behavior implemented in MAC
address filtering code.
With this code refactoring, 'etype_bitmap' array in struct igc_adapter
and 'etype_reg_index' in struct igc_nfc_filter are not needed anymore
and are removed.
Log messages are added to help debugging the ethertype filtering code.

Christoph Hellwig says:
====================
add a new ->ndo_tunnel_ctl method to avoid a few set_fs calls v2
both the ipv4 and ipv6 code have an ioctl each that can be used to create
a tunnel using code that doesn't live in the core kernel or ipv6 module.
Currently they call ioctls on the tunnel devices to create these, for
which the code needs to override the address limit, which is a "feature"
I plan to get rid of.
Instead this patchset adds a new ->ndo_tunnel_ctl that can be used for
the tunnel configuration using struct ip_tunnel_parm. The method is
either invoked from a helper that does the uaccess and can be wired up
as ndo_do_ioctl method, or directly from the magic IPV4/6 ioctls that
create tunnels with kernel space arguments.
Changes since v2:
- properly propagate errors in ipip6_tunnel_prl_ctl

realtek ethernet : use generic power management.
The purpose of this patch series is to remove legacy power management callbacks
from realtek ethernet drivers.
The callbacks performing suspend() and resume() operations are still calling
pci_save_state(), pci_set_power_state(), etc. and handling the powermanagement
themselves, which is not recommended.
The conversion requires the removal of the those function calls and change the
callback definition accordingly.

With legacy PM hooks, it was the responsibility
of a driver to manage PCI states and also
device's power state. The generic approach is
to let PCI core handle the work.
The suspend callback enables/disables PCI wake
on the basis of "cp->wol_enabled" variable
which is unknown to PCI core. To utilise its
need, call device_set_wakeup_enable().
