* Multicast snooping and hello time are the only ones supported at the
moment
* Only pass values to kernel when user sets them, otherwise let kernel
decide default
* Can set multicast snooping on existing bridges
* Tests disabled on Travis CI as the kernel version is too old
* All bridge flags copied from Kernel code, but only the two mentioned
above work

Bridge ports can be set to use the proxy arp features by calling
either LinkSetBrProxyArp() or LinkSetBrProxyArpWiFi().

This patch removes the unnecessary condition of parsing U32 data that
checks if sel.Flags has nl.TC_U32_TERMINAL or sel.Nkeys is not 1.
Because of the modification to U32 that enalbed to specify multiple sel
keys, this condition is not valid anymore. This condition stops the
parsing of U32 fliter data with multiple attributes and this prevents
the users from getting all the necessary attributes, e.g., the class Id
of the filter.

Having the extra data available in the notification for new addresses is useful
to, for instance, filter out temporary addresses or keep track of address
lifetimes.

This adds parsing of the preferred and valid lifetime information from the
netlink IFA_CACHEINFO attribute. They are stored as PreferedLft and ValidLft in
the Addr struct if found.

Currently a LinkByName("bondX") doesn't return the bond specific attributes.
parseBondData needs to update the link that is passed in in order for
the bond's Mode, Miimon etc to be populated correctly.
Removed extra pointer not needed in AddIP
Updated tests
Removed the use of io.SeekCurrent and defined it as a const

This patch adds the advanced u32 match feature support with the
selection keys. It enables the users to crate a complex filter as follow
for instance:
$ tc filter add dev eth0 parent 1: prio 1 u32 match ip dport 80 0xff \
match u32 0x146ca 0xffff at 32 flowid 1:46cb
To expose TcU32Sel and TcU32Key defined in nl package, this patch copies
them to filte.go and their values that require Big-endianness are
handled appropriately in FilterAdd function in filter_linux.go.

Added tests for:
Table FLUSH
Table GET
Table DELETE with filter
Filter match
Use a simple UDP client to create flows into the conntrack for testing purpose
Each test will run in a separate network namespace so can run in parallel
Added kernel module dependencies into the travis file

- Conntrack table FLUSH
- Conntrack table DELETE with filter
The filter is only for IP field
- Conntrack table GET
The flow information is not complete, but the method
returns a simplified structure with basic flow info

This patch adds a new switch case that handles the class ID attribute of
the U32 filter data listed by FilterList. Without this case block the
class ID of the U32 filter is always set to zero. The new test
conditions are added to TestFilterAddDel and TestFilterU32BpfAddDel in
filter_test.go as well.

The go get command and make both fail when executed on
non-linux platforms. Modified it so that there are no
compilation errors when developing in such an
environment.
The non-Linux stub implementation found in netlink_unspecified.go was
missing quite a few Link related functions. Also, some of the
functions that were there took a `*Link` instead of a `Link`.
When developing for Linux on a non-Linux platform, it's useful to have
mock method implementations so the code can easily build locally.
This patch adds such mock implementations for the handle struct, as is
already done in netlink_unspecified.go and route_unspecified.go.
The issue was noticed when building coreos/flannel on Mac. By default
the build would fail with:
pkg/ip/iface.go:32: cannot use link (type *netlink.Device) as type
*netlink.Link in argument to netlink.AddrList:
*netlink.Link is pointer to interface, not interface
Resolved by making interfaces of AddList() implementations the same,
although the reason for having `netlink_unspecified.go` is not fully
clear to me and given that there's only one implementation available.
Perhaps a better idea would be to remove the "interface" altoghether.
Retreive the link type from Netlink GetLink information.
Aim to return the same value as nl-link-list for example :
gre0 gre <noarp,up,running,lowerup> slave-of NONE group 0 ipgre : gre0
gretap0 ether <broadcast,multicast> slave-of NONE group 0 ipgre : gretap0
dummy0 ether 36:d5:87:cf:eb:35 <broadcast,noarp> group 0
tun0 none <pointopoint,multicast,noarp> group 0
tap0 ether 4e:ce:43:4a:82:c2 <broadcast,multicast> group 0
