This is the equivalent of:
bridge link set dev <foo> isolated on|off
Add more bridge port netlink attributes Imported from
include/uapi/linux/if_link.h in Linux v6.3.

Commit 2b008399a4 ("link: add LinkSetGSOIPv4MaxSize and
LinkSetGROIPv4MaxSize") introduced the use of these constants, but they
were added only recently to the golang.org/x/sys/unix package. Update
its version in go.mod and use the pre-defined constants instead of
duplicating them.

Add two new methods to allow setting GSO and GRO max size attributes only.
They make it much easier to enable IPv4 BIG TCP [0].
The equivalent iproute2 commands are:
$ ip link set $link gso_ipv4_max_size $maxSize
$ ip link set $link gro_ipv4_max_size $maxSize
Also add tests for them. We already do support the IPv6 counterpart via
543bb1cade ("link: add LinkSetGSOMaxSize and LinkSetGROMaxSize").

Use the constants provided in the golang.org/x/sys/unix package instead
of locally defining them, as done in commit c94808a88b ("link: add
support for IFLA_GRO_MAX_SIZE").

Add support for the new IFLA_GRO_MAX_SIZE attribute which is needed to
enable BIG TCP[1] properly. Define the attribute in the local link
attributes (nl/link_linux.go) because it isn't yet present in Go's
x/sys/unix package. Also add a test for it.

This PR refers to PR@lebauce and add some changes.
- Added some tests to retrieve bond slave information.
- Link.BondSlave is changed to LinkSlave interface.
- BondSlaveState.String() returns UPPER case. (same as iproute2)
- BondSlaveMiiStatus.String() returns UPPER case. (same as iproute2)
- Add a new Link type, IPoIB, that exposes the following IPoIB attributes:
* IFLA_IPOIB_PKEY
* IFLA_IPOIB_MODE
* IFLA_IPOIB_UMCAST
- Suppport Deserialize for IPoIB link attributes in LinkDeserialize()
- Support IPoIB attributes in LinkAdd()
For tuntap interfaces, return a TunTap Interface instead of
a Generic link when retrieving the interface.
Use netlink extended attributes to populate the Link attributes
for the tuntap link.
In case of older tun driver which does not provide these
attributes, use sysfs to retrieve these attributes.
This commit also adds Owner and Group attributes for the TunTap
Link.

XFRM interfaces are available in Linux Kernel 4.19+
When an IF_ID is applied to a XFRM policy and state, the corresponding
traffic will be sent through the virtual interface with the same IF_ID.
Add support for setting InfiniBand Node and Port GUID address
configuration of a VF when InfiniBand HCA are used with SR-IOV mode.

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.

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

* 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.
