Old method uses the addresses in the config files which could lead serious
problem when multiple tests running in different hosts.
This patch adds a new macaddress pool algorithm, it generates the mac prefix
based on mac address of the host, and fix it to correspond to IEEE802.
When user have set the mac_prefix in the config file, we should use it instead
of the dynamic generated mac prefix.
Add a parameter like 'preserve_mac', to preserve the original mac address, for
things like migration.
MAC addresses are recorded into a dictionary 'address_pool' in following
format: {{'20100310-165222-Wt7l:0' : 'AE:9D:94:6A:9b:f9'},...}
20100310-165222-Wt7l : instance attribute of VM
0 : index of NIC
AE:9D:94:6A:9b:f9 : mac address
Use 'vm instance' + 'nic index' as the key, macaddress is the value.
Changs from v1:
- Use 'vm instance' + 'nic index' as the key of address_pool, address is value.
- Put 'mac_lock' and 'address_pool' to '/tmp', for sharing them to other
autotest instances running on the same host.
- Change function names for less confusion.
- Do not copy 'vm.instance' in vm.clone()
- Split 'adding get_ifname function' to another patch

It's more clear to use 'nic_mode + nic_index + vnc_port' than 'tap0',
It's also unique for one guest.

The kvm_net_utils.py is a just a place that wraps common network
related commands which is used to do the network-related tests.
Use -1 as the packet ratio for loss analysis.
Use quiet mode when doing the flood ping.
Changes from v1:
- Use None to indicate that the session should be local in raw_ping
- Use session.sendline("\003") to send (ctrl+c) signal
- Use None to indicate that the session should be local
- Fix of coding style

This test use ping to check the virtual nics, it contains two kinds of test:
1. Packet loss ratio test, ping the guest with different size of packets.
2. Stress test, flood ping guest then use ordinary ping to test the network.
We could not raise an error when flood ping failed, it's too strict.
But we must check the ping result before/after flood-ping.
The interval and packet size could be configurated through tests_base.cfg
Changes from v1:
- Improve error message

This test is the basic test of transfering file between host and guest. Try to
transfer a large file from host to guest, and transfer it back to host, then
compare the files by diff command.
The default file size is 4000M, scp timeout is 1000s. It means if the average
speed is less than 4M/s, this test will be fail.
We can extend this test by using another disk later, then we can transfer larger
files without the limit of first disk size.
Changes from v1:
- Use md5 to verify the integrity of files
- Try to use autotest API, such as, utils.system()

This test mainly covers TCP sent from host to guest and from guest to host
with repeatedly turn on/off NIC promiscuous mode.
Changes from v1:
- Don't abruptly fail the whole test if we get a failure for a single size

Use 'ping' to test send/recive multicat packets. Flood ping test is also added.
Limit guest network as 'bridge' mode, because multicast packets could not be
transmitted to guest when using 'user' network.
Add join_mcast.py for joining machine into multicast groups.
Changes from v1:
- Just flush the firewall rules with iptables -F

This case just snoop tftp packet through tcpdump, it depends on public dhcp
server, better to test it through dnsmasq.
FIXME: Use dnsmasq for pxe test

Add network load by netperf, server is launched on guest, execute netperf
client with different protocols on host. if all clients execute successfully,
case will be pass. Test result will be record into result.txt.
Now this case only tests with "TCP_RR TCP_CRR UDP_RR TCP_STREAM TCP_MAERTS
TCP_SENDFILE UDP_STREAM". DLPI only supported by Unix, unix domain test is
not necessary, so drop test of DLPI and unix domain.

This is an enhancement of existed vlan test. Rename the vlan_tag.py to vlan.py,
it is more reasonable.
. Setup arp from "/proc/sys/net/ipv4/conf/all/arp_ignore"
. Multiple vlans exist simultaneously
. Test ping between same and different vlans
. Test by TCP data transfer, floop ping between same vlan
. Maximal plumb/unplumb vlans

following condition, it's difficult to realise when parsing config file or
calling get_sub_dict*().
extra_params += ' str1'

The latest case contains TX/RX/SG/TSO/GSO/GRO/LRO test. RTL8139 NIC doesn't
support TSO, LRO, it's too old, so drop offload test from rtl8139. LRO, GRO
are only supported by latest kernel, virtio nic doesn't support receive
offloading function.
Initialize the callbacks first and execute all the sub tests one by one, all
the result will be check at the end.
When execute this test, vhost should be enabled, then most of new feature can
be used. Vhost doestn't support VIRTIO_NET_F_MRG_RXBUF, so do not check large
packets in received offload test.
Transfer files by scp between host and guest, match new opened TCP port by
netstat. Capture the packages info by tcpdump, it contains package length.
FIXME: Quary supported offload function by 'ethtool'
