Nikolay Aleksandrov fdbdd356f0 ip: bridge_slave: add support for per-port group_fwd_mask
This patch adds the iproute2 support for getting and setting the
per-port group_fwd_mask. It also tries to resolve the value into a more
human friendly format by printing the known protocols instead of only
the raw value.
The man page is also updated with the new option.

William Tu 9a1381d509 gre: add support for ERSPAN tunnel
The patch adds ERSPAN type II tunnel support. The implementation is
based on the draft at
 https://tools.ietf.org/html/draft-foschiano-erspan-01.

One of the purposes is for Linux box to be able to receive ERSPAN
monitoring traffic sent from the Cisco switch, by creating a ERSPAN
tunnel device. In addition, the patch also adds ERSPAN TX, so traffic
can also be encapsulated into ERSPAN and sent out.

The implementation reuses the key as ERSPAN session ID, and
field 'erspan' as ERSPAN Index fields:
./ip link add dev ers11 type erspan seq key 100 erspan 123 \
		local 172.16.1.200 remote 172.16.1.100

Daniel Borkmann a872b870a5 bpf: add support for generic xdp
Follow-up to commit c7272ca720 ("bpf: add initial support for
attaching xdp progs") to also support generic XDP. This adds an
indicator for loaded generic XDP programs when programs are loaded
as shown in c7272ca720, but the driver still lacks native XDP
support.

  # ip link
  [...]
  3: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 xdpgeneric qdisc [...]
      link/ether 0c:c4:7a:03:f9:25 brd ff:ff:ff:ff:ff:ff
  [...]

In case the driver does support native XDP, but the user wants
to load the program as generic XDP (e.g. for testing purposes),
then this can be done with the same semantics as in c7272ca720,
but with 'xdpgeneric' instead of 'xdp' command for loading:

  # ip -force link set dev eno1 xdpgeneric obj xdp.o

Robert Shearman 837552b445 iplink: add support for afstats subcommand
Add support for new afstats subcommand. This uses the new
IFLA_STATS_AF_SPEC attribute of RTM_GETSTATS messages to show
per-device, AF-specific stats. At the moment the kernel only supports
MPLS AF stats, so that is all that's implemented here.

The print_num function is exposed from ipaddress.c to be used for
printing the new stats so that the human-readable option, if set, can
be respected.

Example of use:

    $ ./ip/ip -f mpls link afstats dev eth1
    3: eth1
        mpls:
            RX: bytes  packets  errors  dropped  noroute
            9016       98       0       0        0

Daniel Borkmann c7272ca720 bpf: add initial support for attaching xdp progs
Now that we made the BPF loader generic as a library, reuse it
for loading XDP programs as well. This basically adds a minimal
start of a facility for iproute2 to load XDP programs. There
currently only exists the xdp1_user.c sample code in the kernel
tree that sets up netlink directly and an iovisor/bcc front-end.

Since we have all the necessary infrastructure in place already
from tc side, we can just reuse its loader back-end and thus
facilitate migration and usability among the two for people
familiar with tc/bpf already. Sharing maps, performing tail calls,
etc works the same way as with tc. Naturally, once kernel
configuration API evolves, we will extend new features for XDP
here as well, resp. extend dumping of related netlink attributes.

Minimal example:

  clang -target bpf -O2 -Wall -c prog.c -o prog.o
  ip [-force] link set dev em1 xdp obj prog.o       # attaching
  ip [-d] link                                      # dumping
  ip link set dev em1 xdp off                       # detaching

For the dump, intention is that in the first line for each ip
link entry, we'll see "xdp" to indicate that this device has an
XDP program attached. Once we dump some more useful information
via netlink (digest, etc), idea is that 'ip -d link' will then
display additional relevant program information below the "link/
ether [...]" output line for such devices, for example.

Moshe Shemesh 56e9f0ab19 ip link: Add support to configure SR-IOV VF to vlan protocol 802.1ad (VST QinQ)
Introduce a new API that exposes a list of vlans per VF (IFLA_VF_VLAN_LIST),
giving the ability for user-space application to specify it for the VF as
an option to support 802.1ad (VST QinQ).

We introduce struct vf_vlan_info, which extends struct vf_vlan and adds
an optional VF VLAN proto parameter.
Default VLAN-protocol is 802.1Q.

Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
compatibility with older kernel versions.

Suitable ip link tool command examples:
 - Set vf vlan protocol 802.1ad (S-TAG)
	ip link set eth0 vf 1 vlan 100 proto 802.1ad
 - Set vf vlan S-TAG and vlan C-TAG (VST QinQ)
	ip link set eth0 vf 1 vlan 100 proto 802.1ad vlan 30 proto 802.1Q
 - Set vf to VST (802.1Q) mode
	ip link set eth0 vf 1 vlan 100 proto 802.1Q
 - Or by omitting the new parameter (backward compatible)
	ip link set eth0 vf 1 vlan 100
