The IFLA_* constants in in x/sys/unix were updated to Linux 4.15 in
golang/sys@88d2dcc510, so use these instead of locally duplicating
them.

This test spawns a go routine that subscribe for some
events while the main thread will close the socket.
The go routine will returns after 5s when the timetout
on the recv fires and the fd is actually == -1

If the socket is closed the recv that are waiting for messages
are not woken up. The result especially for Subscribe socket is
most likely a go routine leak.
This commit introduces a method to set the timeout

Add support for setting trust state of a VF. This allows restricting
certain operations on VF when its untrusted such as disabling
promiscuous mode.

Add bond parameters corresponding to:
* IFLA_BOND_AD_ACTOR_SYS_PRIO
* IFLA_BOND_AD_USER_PORT_KEY
* IFLA_BOND_AD_ACTOR_SYSTEM
* IFLA_BOND_TLB_DYNAMIC_LB
These are available in new(ish) kernels.
* 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 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.

The filter is only for IP field
- Conntrack table GET

returns a simplified structure with basic flow info

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.
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

* Add netlink definitions for extra IFLAs
The relevant IFLA_* are defined in the kernel but not in the syscall
package.
* Parameterize the return value of loadSimpleBpf
Allow the return value of the bpf program created by loadSimpleBpf to
be specified by the caller. Before this, the value was hardcoded to 1.
* Add support for a new IFLA that enables using a bpf program as a
filter early in the driver path of some NICs.
* Add a test for set/get of an xdp program. Since currently, the XDP
IFLA is optional, check that the hardware supports it before trying to
set the field.

Key length used in DeserializeSerialise XfrmAlgo tests is
endianess dependant. Correction needed to have
TestXfrmAlgoDeserializeSerialize and
TestXfrmAlgoAuthDeserializeSerialize
pass ok on ppc64 arch (big endian).
An issue happens when netlink.LinkSubscribe is called back to back, even
when there is a Close() of the netlink socket (via the done chan
parameter). The issue seems to stem from the fact that after the
close/open happen together, the same fd is allocated. This lets the
s.Receive() calls succeed in more than one goroutine, which causes the
updates to issue randomly since the same fd has multiple readers and the
original Subscribe never finishes.
After a Close(), mark the Socket as invalid (-1) so that calls to
Send()/Receive() will fail going forward.
