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).

See .../extras/pg/checksum_offload.pg for a nontrivial example, which
deliberately sets bogus ip and udp checksums in the generated packets,
then fixes the mess with (software emulated) hardware checksum
offload.
Validated via "pcap dispatch trace on max 1000 buffer-trace pg-input 100".
Packets stuffed into loop1-output have the configured bogus ip and udp
checksums. vnet_calc_checksums_inline(...) fixes the checksums, which
are correct when packets visit loop1-tx.
The packet generator is a dumb robot in this regard. If you ask for a
ridiculous flag combination - example: ip4 and ip6 - your mileage may
vary.

Allow for setting the maximum number of generated packets to be included
in the frame passed to next nodes. This is very important for testing
code which may be susceptible to multi-frame vs single-frame bugs (e.g.,
code that is doing re-ordering where packets may be buffered between
frames).
Update:
- remove redundant packet "rate" option.
- reduce n_max_frame to u32 as that's what pulled from the CLI.

previously, PG and virtio interfaces calculate wrong l3 and l4

The fast path almost always has to deal with the real
pointers. Deriving the frame pointer from a frame_index requires a
load of the 32bit frame_index from memory, another 64bit load of the
heap base pointer and some calculations.
Lets store the full pointer instead and do a single 64bit load only.
This helps avoiding problems when the heap is grown and frames are
allocated below vm->heap_aligned_base.

The unit and code coverage tests are boring. The rest of the patch
involves test and packet-generator infra cleanups.
Teach the "make test-xxx" family of targets to set the api test plugin
path correctly, to make "binary-api <api-message-name> <args>" debug
CLI commands work correctly in the "make test"
environment. Unfortunately involves both the top-level and test
Makefiles.
Add a minor pg cli feature, a CLI to manually set
s->sw_if_index[VLIB_TX].
Consider the case where one configures an interface with both a
device-input and an output feature. To test the output feature using
the pg, it's necessary to inject packets into the interface output
node with both b->sw_if_index[VLIB_TX] and b->sw_if_index[VLIB_RX] set
correctly. For example:
packet-generator new {
name tx
limit 15
size 128-128
interface local0 # rx: device input feature not configured on local0
tx-interface loop0 # tx: output node requires b->sw_if_index[VLIB_TX]
node loop0-output
data {
hex 0x01005e7ffffa000dead0000008000102030405060708090a0b0c0d0e0f0102030405
}
}
Fix a longstanding bug in the packet generator stream setup. Remove
kludges which set b->sw_if_index[VLIB_TX] to ~0 [in multiple places]
instead of using the stream value s->sw_if_index[VLIB_TX], and setting
THAT datum correctly.

Currently, buffer index is calculated as a offset to the physmem
region shifted by log2_cacheline size.
When DPDK is used we "hack" physmem data with information taken from
dpdk mempool. This makes physmem code not usable with DPDK.
This change makes buffer memory start and size independent of physmem
basically allowing physmem to be used when DPDK plugin is loaded.

This patch deprecates stack-based thread identification,
Also removes requirement that thread stacks are adjacent.
Finally, possibly annoying for some folks, it renames
all occurences of cpu_index and cpu_number with thread
index. Using word "cpu" is misleading here as thread can
be migrated ti different CPU, and also it is not related
to linux cpu index.

Multiple DHCP (4 and/or 6) servers can be added and removed through multiple calls to the 'set dhcp server' API.
All 4/6/ discover/solicit messages will then be replicated to all servers in the list. The expectation is that the servers/system is configured in such a way that this is viable.
If VSS information is providied for the clinet VRF which also has multiple servers configured, then the same VSS information is sent to each server. Likewise the source address of packets sent to from VPP to each server is the same.
