Attempts to connect to a local address with a socket bound
to a device with the local address hangs if there is no listener:

  $ ip addr sh dev eth1
  3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 02:e0:f9:1c:00:37 brd ff:ff:ff:ff:ff:ff
    inet 10.100.1.4/24 scope global eth1
       valid_lft forever preferred_lft forever
    inet6 2001:db8:1::4/120 scope global
       valid_lft forever preferred_lft forever
    inet6 fe80::e0:f9ff:fe1c:37/64 scope link
       valid_lft forever preferred_lft forever

  $ vrf-test -I eth1 -r 10.100.1.4
  <hangs when there is no server>

(don't let the command name fool you; vrf-test works without vrfs.)

The problem is that the original intended device, eth1 in this case, is
lost when the tcp reset is sent, so the socket lookup does not find a
match for the reset and the connect attempt hangs. Fix by adjusting
orig_oif for local traffic to the device from the fib lookup result.

With this patch you get the more user friendly:
  $ vrf-test -I eth1 -r 10.100.1.4
  connect failed: 111: Connection refused

orig_oif is saved to the newly created rtable as rt_iif and when set
it is used as the dif for socket lookups. It is set based on flowi4_oif
passed in to ip_route_output_key_hash_rcu and will be set to either
the loopback device, an l3mdev device, nothing (flowi4_oif = 0 which
is the case in the example above) or a netdev index depending on the
lookup path. In each case, resetting orig_oif to the device in the fib
result for the RTN_LOCAL case allows the actual device to be preserved
as the skb tx and rx is done over the loopback or VRF device.

 1. delaying the automatic bring up of VF device to allow udev to change name.

 4. minor cleanups
 5. allow setting send/receive buffer size with ethtool.

Control the size of the buffer areas via ethtool ring settings.
They aren't really traditional hardware rings, but host API breaks
receive and send buffer into chunks. The final size of the chunks are
controlled by the host.

The default value of send and receive buffer area for host DMA
is much larger than it needs to be. Experimentation shows that
4M receive and 1M send is sufficient.

If slave device doesn't support MAC address change then it

net: sched: let the offloader decide what to offload

Currently there is a Qdisc_class_ops->tcf_cl_offload callback
that is called to find out if cls would offload rule or not.
This is only supported by sch_ingress and sch_clsact.
So the Qdisc are to decide. However, the driver knows what is he
able to offload, so move the decision making to drivers completely.
Just pass classid there and provide set of helpers to allow
identification of qdisc.

As a side effect, this actually allows clsact egress rules
offload in mlxsw.
