The num_rx_pools value is overwritten when we reinitialize the queue
configuration. In reality we shouldn't need to be updating the value since
it is redone every time we call into ixgbe_setup_tc so for now just drop
the spots where we were incrementing or decrementing the value.

In order for RSS to work on the macvlan pools of the X550 we need to
populate the MRQC, RETA, and RSS key values for each pool. This patch makes
it so that we now take care of that.

In addition I have dropped the macvlan specific configuration of psrtype
since it is redundant with the code that already exists for configuring
this value.

If the number of VFs are changed we need to reinitialize the part since the
offset for the device and the number of pools will be incorrect. Without
this change we can end up seeing Tx hangs and dropped Rx frames for
incoming traffic.

In addition we should drop the code that is arbitrarily changing the
default pool and queue configuration. Instead we should wait until the port
is reset and reconfigured via ixgbe_sriov_reinit.

When SR-IOV was enabled the macvlan offload was configuring several filters
with the wrong pool value. This would result in the macvlan interfaces not
being able to receive traffic that had to pass over the physical interface.

To fix it wrap the pool argument in the VMDQ_P macro which will add the
necessary offset to get to the actual VMDq pool

Netfilter/IPVS updates for net-next

The following patchset contains Netfilter/IPVS updates for your
net-next tree:

1) Free hooks via call_rcu to speed up netns release path, from
   Florian Westphal.

2) Reduce memory footprint of hook arrays, skip allocation if family is
   not present - useful in case decnet support is not compiled built-in.
   Patches from Florian Westphal.

3) Remove defensive check for malformed IPv4 - including ihl field - and
   IPv6 headers in x_tables and nf_tables.

4) Add generic flow table offload infrastructure for nf_tables, this
   includes the netlink control plane and support for IPv4, IPv6 and
   mixed IPv4/IPv6 dataplanes. This comes with NAT support too. This
   patchset adds the IPS_OFFLOAD conntrack status bit to indicate that
   this flow has been offloaded.

5) Add secpath matching support for nf_tables, from Florian.

6) Save some code bytes in the fast path for the nf_tables netdev,
   bridge and inet families.

7) Allow one single NAT hook per point and do not allow to register NAT
   hooks in nf_tables before the conntrack hook, patches from Florian.

8) Seven patches to remove the struct nf_af_info abstraction, instead
   we perform direct calls for IPv4 which is faster. IPv6 indirections
   are still needed to avoid dependencies with the 'ipv6' module, but
   these now reside in struct nf_ipv6_ops.

9) Seven patches to handle NFPROTO_INET from the Netfilter core,
   hence we can remove specific code in nf_tables to handle this
   pseudofamily.

10) No need for synchronize_net() call for nf_queue after conversion
    to hook arrays. Also from Florian.

11) Call cond_resched_rcu() when dumping large sets in ipset to avoid
    softlockup. Again from Florian.

12) Pass lockdep_nfnl_is_held() to rcu_dereference_protected(), patch
    from Florian Westphal.

13) Fix matching of counters in ipset, from Jozsef Kadlecsik.

14) Missing nfnl lock protection in the ip_set_net_exit path, also
    from Jozsef.

15) Move connlimit code that we can reuse from nf_tables into
    nf_conncount, from Florian Westhal.

And asorted cleanups:

16) Get rid of nft_dereference(), it only has one single caller.

17) Add nft_set_is_anonymous() helper function.

18) Remove NF_ARP_FORWARD leftover chain definition in nf_tables_arp.

19) Remove unnecessary comments in nf_conntrack_h323_asn1.c
    From Varsha Rao.

20) Remove useless parameters in frag_safe_skb_hp(), from Gao Feng.

21) Constify layer 4 conntrack protocol definitions, function
    parameters to register/unregister these protocol trackers, and
    timeouts. Patches from Florian Westphal.

22) Remove nlattr_size indirection, from Florian Westphal.

23) Add fall-through comments as -Wimplicit-fallthrough needs this,
    from Gustavo A. R. Silva.

24) Use swap() macro to exchange values in ipset, patch from
    Gustavo A. R. Silva.

As of now, there're two sk_family are traced with sock:inet_sock_set_state,
which are AF_INET and AF_INET6.
So the sk_family are exposed as well.
Then we can conveniently use it to do the filter.

Both sk_family and sk_protocol are showed in the printk message, so we need
not expose them as tracepoint arguments.

Allow a process bound to a VRF to connect to a linklocal address.
Currently, this fails because of a mismatch between the scope of the
linklocal address and the sk_bound_dev_if inherited by the VRF binding:
    $ ssh -6 fe80::70b8:cff:fedd:ead8%eth1
    ssh: connect to host fe80::70b8:cff:fedd:ead8%eth1 port 22: Invalid argument

Relax the scope check to allow the socket to be bound to the same L3
device as the scope id.

This makes ipv6 linklocal consistent with other relaxed checks enabled
by commits 1ff23bee ("net: l3mdev: Allow send on enslaved interface")
and 7bb387c5 ("net: Allow IP_MULTICAST_IF to set index to L3 slave").

frame size not only controls the RX packet size, but also controls the
TX packet size. the RX packets whose size are greater than the setting
value will be dropped.
