The TW_IOCTL_GET_LOCK ioctl uses do_gettimeofday() to check whether a
lock has expired. This can misbehave due to a concurrent settimeofday()
call, as it is based on 'real' time, and it will overflow in y2038 on
32-bit architectures, producing unexpected results when used across the
overflow time.

This changes it to using monotonic time, using ktime_get() to simplify

bfa_aen_entry_s is passed through a netlink socket that can be read by
either 32-bit or 64-bit processes, but the data format is different
between the two on current implementations.

Originally, this was using a 'struct timeval', which also suffers from
getting redefined with a new libc implementation.

With this patch, the layout gets fixed to having two 64-bit members for
the time, making it the same on 32-bit kernels and 64-bit kernels
running either compat or native user space including x32.

Provided that the new header file gets used to recompile any 32-bit
application binaries, this will fix running those on a 64-bit kernel
(with or without this patch) e.g. in a container environment, and it
will make binaries work that will be built against a future 32-bit glibc
that uses a 64-bit time_t, and avoid the y2038 overflow there.

However, this also breaks compatibility with any existing 32-bit binary
running on a native 32-bit kernel, those must be recompiled against the
new header, which in turn makes them incompatible with older kernels
unless the same change gets applied there.

Obviously this patch should only be applied when the benefits outweigh
the possible breakage. I'm posting it under the assumption that there
are no open-source tools using the netlink interface, and that users of
the binaries provided by qlogic for SLES10/11 and RHEL5/6 are not
actually being used on new future systems with 32-bit x86 kernels.

bfa_aen_entry_s is passed to user space in a netlink message, but is
defined using a 'struct timeval' and an 'enum' that are not only
different between architectures, but also between 32-bit user space and
64-bit kernels they may run on, as well as depending on the particular C
library that defines timeval.

This changes the in-kernel definition to no longer use the timeval type
directly but instead use two open-coded 'unsigned long' members.  This
keeps the existing ABI, but making the variable unsigned also helps make
it work after y2038, until it overflows in 2106.

Since the macro becomes overly complex at this point, I'm changing it to
an inline function for readability.

I'm not changing the 32-bit user-space ABI at this point, to keep the
changes separate, I deally this would be defined using the same binary
layout for all architectures.

The bfa_get_log_time() returns a 64-bit timestamp that does not suffer

0xffffffff80000000 in y2038 and produce wrong results.

Tuntap and similar devices can inject GSO packets. Accept type
VIRTIO_NET_HDR_GSO_UDP, even though not generating UFO natively.

Processes are expected to use feature negotiation such as TUNSETOFFLOAD
to detect supported offload types and refrain from injecting other
packets. This process breaks down with live migration: guest kernels
do not renegotiate flags, so destination hosts need to expose all
features that the source host does.

Partially revert the UFO removal from 182e0b6b~1..d9d30adf.
This patch introduces nearly(*) no new code to simplify verification.
It brings back verbatim tuntap UFO negotiation, VIRTIO_NET_HDR_GSO_UDP
insertion and software UFO segmentation.

It does not reinstate protocol stack support, hardware offload
(NETIF_F_UFO), SKB_GSO_UDP tunneling in SKB_GSO_SOFTWARE or reception
of VIRTIO_NET_HDR_GSO_UDP packets in tuntap.

To support SKB_GSO_UDP reappearing in the stack, also reinstate
logic in act_csum and openvswitch. Achieve equivalence with v4.13 HEAD
by squashing in commit 93991221 ("net: skb_needs_check() removes
CHECKSUM_UNNECESSARY check for tx.") and reverting commit 8d63bee6
("net: avoid skb_warn_bad_offload false positives on UFO").

(*) To avoid having to bring back skb_shinfo(skb)->ip6_frag_id,
ipv6_proxy_select_ident is changed to return a __be32 and this is
assigned directly to the frag_hdr. Also, SKB_GSO_UDP is inserted
at the end of the enum to minimize code churn.

Tested
  Booted a v4.13 guest kernel with QEMU. On a host kernel before this
  patch `ethtool -k eth0` shows UFO disabled. After the patch, it is
  enabled, same as on a v4.13 host kernel.

  A UFO packet sent from the guest appears on the tap device:
    host:
      nc -l -p -u 8000 &
      tcpdump -n -i tap0

    guest:
      dd if=/dev/zero of=payload.txt bs=1 count=2000
      nc -u 192.16.1.1 8000 < payload.txt

  Direct tap to tap transmission of VIRTIO_NET_HDR_GSO_UDP succeeds,
  packets arriving fragmented:

5:   first->next_to_watch = tx_desc      napi_consume_skb(tx_buffer->skb ..);
6:   writel(i, tx_ring->tail);

The read_barrier_depends is insufficient to ensure that tx_buffer->skb does not
get loaded prior to tx_buffer->next_to_watch, which then results in loading
a stale skb pointer. This patch replaces the read_barrier_depends with
smp_rmb to ensure loads are ordered with respect to the load of
tx_buffer->next_to_watch.

The current method for notifying clients of l2 parameters is broken
because we fail to copy the new parameters to the client instance

This patch first introduces the i40evf_client_get_params function to
prevent code duplication in the i40evf_client_add_instance and the
i40evf_notify_client_l2_params functions.  We then fix the notify l2
params function to actually copy the parameters to client instance
struct and do the same in the *_add_instance' function.  Lastly this
patch reorganizes the priority in which client tasks fire so that if the
flag for notifying l2 params is set, it will trigger before the open
because the client needs these new parameters as part of a client open
