is reasonable, since we indeed send the pkt by the "ovsbr0" interface.
The wrong mac table lead all the packets to the VM go to the "ovsbr0"
in the end, which ends up with all packets being lost, until the guest
send a ARP quest (or reply) to refresh the mac learning table.
Jianfeng then came up with a solution I have thought of firstly but NAKed
by myself, concerning it has potential issues [0]. The solution is as title
stated: broadcast the RARP packet by injecting it to the receiving mbuf
arrays at rte_vhost_dequeue_burst(). The re-bring of that idea made me
think it twice; it looked like a false concern to me then. And I had done
a rough verification: it worked as expected.
[0]: http://dpdk.org/ml/archives/dev/2016-February/033527.html
Another note is that while preparing this version, I found that DPDK has
some ARP related structures and macros defined. So, use them instead of
the one from standard header files here.

examples/l3fwd: rework exact-match
Current implementation of Exact-Match uses different execution path than
for LPM. Unifying them allows to reuse big part of LPM code and sightly
increase performance of Exact-Match.
Main changes:
-------------
* Packet classification stage is separated from the rest of path for both
LPM and EM.
* Packet processing, modifying and transmit part is the same for LPM and EM
and mostly based on the current LPM implementation.
* Shared code is moved to the common file "l3fwd_sse.h".
* While sequential packet classification in EM path, seems to be faster
than using multi hash lookup, used before, it is used by default. Old
implementation is moved to the file l3fwd_em_hlm_sse.h and can be enabled
with HASH_LOOKUP_MULTI global define in compilation time.

$ $QEMU -smp cores=2,sockets=1 -m 4G -cpu host -enable-kvm \

3. Start l2fwd in VM
$ ./examples/l2fwd/build/l2fwd -c 0x1 -n 4 -m 1024 -- -p 0x1
4. Use ixia to inject packets in a small data bit rate.
Error:
vhost-switch keeps printing error message:
failed to allocate memory for mbuf.
Root cause:
How many mbufs allocated for a port is calculated by below formula.
NUM_MBUFS_PER_PORT = ((MAX_QUEUES*RTE_TEST_RX_DESC_DEFAULT) + \
(num_switching_cores*MAX_PKT_BURST) + \
(num_switching_cores*RTE_TEST_TX_DESC_DEFAULT) +\
(num_switching_cores*MBUF_CACHE_SIZE))
We suppose num_switching_cores is 1 and MBUF_CACHE_SIZE is 128.
And when initializing port, master core fills mbuf mempool cache,
so there would be some left in that cache, for example 121.
So total mbufs which can be used is:
(MAX_PKT_BURST + MBUF_CACHE_SIZE - 121) = (32 + 128 - 121) = 39.
What makes it worse is that there is a buffer to store mbufs
(which will be tx_burst to physical port), if it occupies some mbufs,
there will be possible < 32 mbufs left, so vhost dequeue prints out
this msg.
In all, it fails to include master core's mbuf mempool cache.

examples/l3fwd: modularize
The main problem with l3fwd is that it is too monolithic with everything
being in one file, and the various options all controlled by compile time
flags. This means that it's hard to read and understand, and when making
any changes, you need to go to a lot of work to try and ensure you cover
all the code paths, since a compile of the app will not touch large parts
of the l3fwd codebase.
Following changes were done to fix the issues mentioned above
- Split out the various lpm and hash specific functionality into separate
files, so that l3fwd code has one file for common code e.g. args
processing, mempool creation, and then individual files for the various
forwarding approaches.
Following are new file lists
main.c (Common code for args processing, memppol creation, etc)
l3fwd_em.c (Hash/Exact match aka 'EM' functionality)
l3fwd_em_sse.h (SSE4_1 buffer optimizated 'EM' code)
l3fwd_lpm.c (Longest Prefix Match aka 'LPM' functionality)
l3fwd_lpm_sse.h (SSE4_1 buffer optimizated 'LPM' code)
l3fwd.h (Common include for 'EM' and 'LPM')
- The choosing of the lpm/hash path should be done at runtime, not
compile time, via a command-line argument. This will ensure that
both code paths get compiled in a single go
Following examples show runtime options provided
Select 'LPM' or 'EM' based on run time selection f.e.
> l3fwd -c 0x1 -n 1 -- -p 0x1 -E ... (EM)
> l3fwd -c 0x1 -n 1 -- -p 0x1 -L ... (LPM)
Options "E" and "L" are mutualy-exclusive.
If none selected, "L" is default.

examples/vhost: add virtio offload
Change the codes in vhost sample to test virtio offload feature.
These changes include,
1. add two test options: tx-csum and tso.
2. add virtio_tx_offload() function to test vhost TX offload feature
for VM to NIC case;
however, for VM to VM case, it doesn't need to call this function,
the reason is explained in patch 2.

vhost: add guest offload setting
Add guest offload setting in vhost lib.
Virtio 1.0 spec (5.1.6.4 Processing of Incoming Packets) says:
1. If the VIRTIO_NET_F_GUEST_CSUM feature was negotiated, the
VIRTIO_NET_HDR_F_NEEDS_CSUM bit in flags can be set: if so,
the packet checksum at offset csum_offset from csum_start
and any preceding checksums have been validated. The checksum
on the packet is incomplete and csum_start and csum_offset
indicate how to calculate it (see Packet Transmission point 1).
2. If the VIRTIO_NET_F_GUEST_TSO4, TSO6 or UFO options were
negotiated, then gso_type MAY be something other than
VIRTIO_NET_HDR_GSO_NONE, and gso_size field indicates the
desired MSS (see Packet Transmission point 2).
In order to support these features, the following changes are added,
1. Extend 'VHOST_SUPPORTED_FEATURES' macro to add the offload features negotiation.
2. Enqueue these offloads: convert some fields in mbuf to the fields in virtio_net_hdr.
There are more explanations for the implementation.
For VM2VM case, there is no need to do checksum, for we think the
data should be reliable enough, and setting VIRTIO_NET_HDR_F_NEEDS_CSUM
at RX side will let the TCP layer to bypass the checksum validation,
so that the RX side could receive the packet in the end.
In terms of us-vhost, at vhost RX side, the offload information is
inherited from mbuf, which is in turn inherited from TX side. If we
can still get those info at RX side, it means the packet is from
another VM at same host. So, it's safe to set the
VIRTIO_NET_HDR_F_NEEDS_CSUM, to skip checksum validation.

The patch
c344eab3ee has moved the hardware definition of CPU flags.
Now the functions checking these hardware flags are also moved.
The function rte_cpu_get_flag_enabled() is no more inline.
The benefits are:
- remove rte_cpu_feature_table from the ABI (recently added)
- hide hardware details from the API
- allow to adapt structures per arch (done in next patch)
