This patch improves few aspects of interrupt handling:
- update to current interrupt allocation API
  (use pci_alloc_irq_vectors() instead of deprecated pci_enable_msi())
- this implicitly will allocate a MSI-X interrupt if available
- get rid of flag RTL_FEATURE_MSI
- remove some dead code, intentionally disabling (unreliable) MSI
  being partially available on old PCI chips.

The patch works fine on a RTL8168evl (chip version 34) and on a
RTL8169SB (chip version 04).

Converting pernet_operations (part #3)

This patchset continues to review and to convert pernet_operations
to async. Where it is possible, they are grouped by type of actions
init/exit methods ([1/28], for example). I hope this will make
the review a little bit easier. The changes are tree-wide: in net, fs,
drivers and security.

These pernet_operations unregister ipvlan net hooks.
nf_unregister_net_hooks() removes hooks one-by-one,
and then frees the memory via rcu. This looks similar
to that happens, when a new hooks is added: allocation
of bigger memory region, copy of old content, and rcu
freeing the old memory. So, all of net code should be
well with this behavior. Also at the time of hook
unregistering, there are no packets, and foreign net
pernet_operations are not interested in others hooks.
So, we mark them as async.

These pernet_operations are from net/sched directory, and they call only
tc_action_net_init() and tc_action_net_exit():

2)There should not be in-flight packets at the time of tc_action_net_exit()
call, or another pernet_operations send packets to dying net (except
netlink). So, it seems they can be marked as async.

We no longer depend on IPV6, but that now causes a link error with
CONFIG_IPV6=m and CONFIG_IPVLAN=y:

drivers/net/ipvlan/ipvlan_core.o: In function `ipvlan_queue_xmit':
ipvlan_core.c:(.text+0x1440): undefined reference to `ip6_route_output_flags'
drivers/net/ipvlan/ipvlan_core.o: In function `ipvlan_l3_rcv':
ipvlan_core.c:(.text+0x1818): undefined reference to `ip6_route_input_lookup'

This adds back the dependency on IPV6, with the option of building without
IPV6, but forcing IPVLAN to be a module when IPV6 is a module.

10GbE Intel Wired LAN Driver Updates 2018-02-26

This series contains updates to ixgbe and ixgbevf only.

Colin Ian King cleans up redundant variable assignments.

Tonghao Zhang updates ixgbe to avoid writing to the hardware when the
redirection table has not changed.

Jake fixes the driver logic for checking and clearing receive timestamp
hangs so that when the PTP_RX_TIMESTAMP_IN_REGISTER flag is set, we no
longer need to check for receive timestamp hangs, which in turn will
stop the spurious log messages.

Emil updates ixgbevf with several features and improvements done in
other drivers, starting with the handling of page addresses so that we
always refer to them using a void pointer.  Added a 'legacy-rx' flag to
allow switching between the old and new receive code paths.  Added
support for using 3K buggers in order 1 page.  Updated the driver to
ensure that calls to ixgbevf_open() are rtnl lock protected and improved
the error handling when setting up multiple queues.  Added support for
providing a buffer with head room and tail room to allow for shared
info, NET_SKB_PAD, and NET_IP_ALIGN, so that we can start using
build_skb to build frames instead of using memcpy() the headers.
Updated the logic of handling rings closer to ixgbe.  Consolidated the
receive paths to reduce duplication when we expand them in the future.
Added build_skb() support to ixgbevf.
