virtio: skip error when probing kernel managed device

virtio PMD could use IO port to configure the virtio device without
using UIO/VFIO driver in legacy mode.

There are two issues with previous implementation:
1) virtio PMD will take over the virtio device(s) blindly even if not
intended for DPDK.
2) driver conflict between virtio PMD and virtio-net kernel driver.

This patch checks if there is kernel driver other than UIO/VFIO managing
the virtio device before using port IO.

If legacy_virtio_resource_init fails and kernel driver other than
VFIO/UIO is managing the device, return 1 to tell the upper layer we
don't take over this device.
For all other IO port mapping errors, return -1.

Note than if VFIO/UIO fails, now we don't fall back to port IO.

notifies the secondary process.

This race-condition became visible during the development of

all host interfaces and then broadcast it by all of them.  It did
notify the switches about the new location of the migrated VM, however,
the mac learning table in the target host is wrong (at least in my
test with OVS):

    $ ovs-appctl fdb/show ovsbr0
     port  VLAN  MAC                Age
        1     0  b6:3c:72:71:cd:4d   10
    LOCAL     0  b6:3c:72:71:cd:4e   10
    LOCAL     0  52:54:00:12:34:68    9
        1     0  56:f6:64:2c:bc:c0    1

Where 52:54:00:12:34:68 is the mac of the VM. As you can see from the
above, the port learned is "LOCAL", which is the "ovsbr0" port. That
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.

-------------

* 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

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.

Ravi Kerur [Thu, 25 Feb 2016 10:24:24 +0000 (11:24 +0100)]
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.
