Fix and optimize DMAC check in ethernet-input node to utilize NIC or
driver which support L3 DMAC-filtering mode so that DMAC check can be
bypassed safely for interfaces/sub-interfaces in L3 mode.
Checking of interface in L3-DMAC-filtering state to avoid DMAC check
require the following:
a) Fix interface driver init sequence for devices which supports L3
DMAC-filtering to indicate its capability and initialize interface
to L3 DMAC-filtering state.
b) Fix ethernet_set_flags() function and its associated callback
flags_change() functions registered by various drivers in interface
infra to provide proper L3 DMAC filtering status.
Maintain interface/sub-interface L3 config count so DMAC checks can be
bypassed if L3 forwarding is not setup on any main/sub-interfaces.

New callback vnet_hw_interface_add_del_mac_address().
Add or delete secondary MAC addresses on a hardware interface.
This will allow packets to be processed which have a destination
MAC address other than the primary programmed MAC address without
needing to put the device into promiscuous mode.

See .../src/vnet/classify/trace_classify.h for the business end
of the scheme.
It would be best to hash pkts, prefetch buckets, and do the primary
table lookups two at a time. The inline as given works, but perf
tuning will be required. "At least it works..."
Add "classify filter" debug cli, for example:
classify filter mask l3 ip4 src dst \
match l3 ip4 dst 192.168.2.10 src 192.168.1.10
Add "pcap rx | tx trace ... filter" to use the current classify filter chain
Patch includes sphinx documentation and doxygen tags.

Spinlock performance improved when implemented with compare_and_exchange
instead of test_and_set. All instances of test_and_set locks were refactored
to use clib_spinlock_t when possible. Some locks e.g. ssvm synchronize
between processes rather than threads, so they cannot directly use
clib_spinlock_t.

- arp-input, registered with the ethernet protocol dispatcher, performs
basic checks and starts the arc
- arp-reply; first feature on the arc replies to requests and learns
from responses (no functional change)
- arp-proxy; checks against the proxy DB
arp-reply and arp-proxy are enabled when the interface is appropriately
configured.

This patch enables bonding numa awareness on multi-socket
server working in active-backeup mode.
The VPP adds capability for automatically preferring slave
with local numa node in order to reduces the load on the
QPI-bus and improve system overall performance in multi-socket
use cases. Users doesn't need to add any extra operation as
usual.

This commit adds a "gso" parameter to existing "create tap..." CLI,
and a "no-gso" parameter for the compatibility with the future,
when/if defaults change.
It makes use of the lowest bit of the "tap_flags" field in the API call
in order to allow creation of GSO interfaces via API as well.
It does the necessary syscalls to enable the GSO
and checksum offload support on the kernel side and sets two flags
on the interface: virtio-specific virtio_if_t.gso_enabled,
and vnet_hw_interface_t.flags & VNET_HW_INTERFACE_FLAG_SUPPORTS_GSO.
The first one, if enabled, triggers the marking of the GSO-encapsulated
packets on ingress with VNET_BUFFER_F_GSO flag, and
setting vnet_buffer2(b)->gso_size to the desired L4 payload size.
VNET_HW_INTERFACE_FLAG_SUPPORTS_GSO determines the egress packet
processing in interface-output for such packets:
When the flag is set, they are sent out almost as usual (just taking
care to set the vnet header for virtio).
When the flag is not enabled (the case for most interfaces),
the egress path performs the re-segmentation such that
the L4 payload of the transmitted packets equals gso_size.
The operations in the datapath are enabled only when there is at least
one GSO-compatible interface in the system - this is done by tracking
the count in interface_main.gso_interface_count. This way the impact
of conditional checks for the setups that do not use GSO is minimized.
"show tap" CLI shows the state of the GSO flag on the interface, and
the total count of GSO-enabled interfaces (which is used to enable
the GSO-related processing in the packet path).
This commit lacks IPv6 extension header traversal support of any kind -
the L4 payload is assumed to follow the IPv6 header. Also it performs
the offloads only for TCP (TSO - TCP segmentation offload).
The UDP fragmentation offload (UFO) is not part of it.
For debug purposes it also adds the debug CLI:
"set tap gso {<interface> | sw_if_index <sw_idx>} <enable|disable>"

In dpdk based bonding, when the bond interface is configured for l2,
it automatically sets the bond interface to promiscuous mode and sets rx
redirect to ethernet-input. This allows traffic to be bridged to
non compute node facing interface when it is received from the compute
node interface.
For native vpp bonding, we need to do similar things. When the bond interface
is configured for l2, we set the slave interfaces to promiscuous mode
and set rx redirect to ethernet-input because dpdk does not know anything
about the bond interface. Likewise, when a new interface is enslaved, we also
need to do the same thing if the bond interface has already been configured
for l2.
