This patch adds support for the stats argument to the bridge
vlan command which will display the per-vlan statistics and the device
each vlan belongs to with its flags. The supported command filtering
options are dev and vid. Also the man page is updated to explain the new
option.
The patch uses the new RTM_GETSTATS interface with a filter_mask to dump
all bridges and ports vlans. Later we can add support for using the
per-device dump and filter it in the kernel instead.
Example:
$ bridge -s vlan show
port vlan id
br0 1 Egress Untagged
RX: 2536 bytes 20 packets
TX: 2536 bytes 20 packets
101
RX: 43158 bytes 50 packets
TX: 43158 bytes 50 packets
eth1 1 Egress Untagged
RX: 2536 bytes 20 packets
TX: 2536 bytes 20 packets
100
RX: 0 bytes 0 packets
TX: 0 bytes 0 packets
101
RX: 43158 bytes 50 packets
TX: 43158 bytes 50 packets
102
RX: 16897 bytes 93 packets
TX: 0 bytes 0 packets
The format is the same as bridge vlan show but with stats, even though
under the hood the calls done to the kernel are different.

All users of genl have the same code to open a genl socket and resolve
the family for their specific protocol. Introduce a helper to initialize
the handle, and use it in all the genl code.

Add two NLA's that allow configuration of Infiniband node or port GUIDs
by referencing the IPoIB net device set over the physical function. The
format to be used is as follows:
ip link set dev ib0 vf 0 node_guid 00:02:c9:03:00:21:6e:70
ip link set dev ib0 vf 0 port_guid 00:02:c9:03:00:21:6e:78

Kernel gained support for filtering link dumps with commit dc599f76c22b
("net: Add support for filtering link dump by master device and kind").
Add support to ip link command. If a user passes master device or
kind to ip link command they are added to the link dump request message.

Use kernel shared buffer occupancy control commands to make snapshot and
clear occupancy watermarks. Also, allow to show occupancy values in a
nice way.

Implement kernel devlink shared buffer interface. Introduce new object
"sb" and allow to browse the shared buffer parameters and also change
configuration.

Follow-up to kernel commit 6c9059817432 ("bpf: pre-allocate hash map
elements"). Add flags support, so that we can pass in BPF_F_NO_PREALLOC
flag for disallowing preallocation. Update examples accordingly and also
remove the BPF_* map helper macros from them as they were not very useful.
