Type: refactor
This patch refactors the offload flags in vlib_buffer_t.
There are two main reasons behind this refactoring.
First, offload flags are insufficient to represent outer
and inner headers offloads. Second, room for these flags
in first cacheline of vlib_buffer_t is also limited.
This patch introduces a generic offload flag in first
cacheline. And detailed offload flags in 2nd cacheline
of the structure for performance optimization.

When using classifier to filter traces, not all packets will be traced.
In that case, we should only count traced packets.

This adds a new data model for counters.
Specifying the errors severity and unit.
A later patch will update vpp_get_stats to take advantage of this.
Only the map plugin is updates as an example.
New .api language:
A new "counters" keyword to define counter sets.
counters map {
none {
severity info;
type counter64;
units "packets";
description "valid MAP packets";
};
bad_protocol {
severity error;
type counter64;
units "packets";
description "bad protocol";
};
};
Each counter has 4 keywords. severity, which is one of error, info or warn.
A type, which is one of counter64 or gauge64.
units, which is a text field using units from YANG.
paths {
"/err/ip4-map" "map";
"/err/ip6-map" "map";
"/err/ip4-t-map" "map";
"/err/ip6-t-map" "map";
};
A new paths keyword that maps the counter-set to a path in the stats segment KV store.
Updated VPP CLI to include severity so user can see error counter severity.

Provide a minimal trace [ip4/ip6 src/dst address] for dropped pkts
when the user specifies "trace add error-drop XXXX", but does not
trace pkts from the original input node.
This is a wireshark dissector problem. Packets thrown at error-drop
may be well-formed, or not. VPP must not crash, no matter what.
The minimal trace capture and decode could be enhanced. Anyone
interested in doing that must consider all of the corner-cases
involved. This version should be at least somewhat useful.
Note that "pcap trace drop ..." - and the packet generator - seem like
the right tools to use when researching more complex issues.

VXLAN uses csum_offload for IPv6 packets.
But without gso node we have csum calculated only for inner
packet.
This patch adds support for outer header csum calculation.
Checksum for inner packet should be calculated before
interface-output node (for example in vxlan node).

Merge two mildly incompatible static inlines, and rename the results
vnet_calc_checksums_inline (...).
The resulting inline has three additional parameters: int is_ip4, int
is_ip6, and int with_gso. All calls manage to pass one or more as
compile-time constants, which causes a certain amount of code to
disappear in each instantiation.

The 9af7e2e87e used a comparison that fd is >= 0 to check that
the pcap needs closing. While the pcap_close() function does
reset the file descriptor to -1, the freshly initialized structure
has it equal to 0.
This causes the VPP to close stdin if the packets are being seen
on pg interface without the capture file being opened.
This triggers the vpp attempting to read from STDIN
(another bug), which results in running out of memory.

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.

when use pcap cli to capture pcakets into two files rx01.pcap && rx02.pcap,
the first time:
1)pcap rx trace on max 100 intfc any file rx01.pcap
2)......the process of capture data to buffer......
3)pcap rx trace off
the second time:
4)pcap rx trace on max 100 intfc any file rx02.pcap
5)......the process of capture data to buffer......
6)pcap rx trace off
the pcap_write function bug in this two lines
pm->n_packets_captured = 0;
if (pm->n_packets_captured >= pm->n_packets_to_capture) referring to calling pcap_close()
will result in that the twice pcap cli both writes the packets
into rx01.pcap, but nothing into rx02.pcap. Beside, the rx02.pcap
file will not be created.
solution: separate the pcap_close() out of pcap_write()

ASSERT (b[0]->current_length > 0) fails in single loop of
function vnet_interface_output_node_inline_gso.
Under 'do_segmentation' condition, there are two places in code
which execute "continue" in while-loop without incrementing the
pointer to next buffer which is wrong behavior. In fact, at one
place, current buffer is also freed. In which case, during next
iteration buffer ptr still points to free buffer which current
length is 0 and triggers the above assert.

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>"
