net: bridge: vlan options: nest the tunnel options
After a discussion with Roopa about the new tunnel vlan option, she
suggested that we'll be adding more tunnel options and attributes, so
it'd be better to have them all grouped together under one main vlan
entry tunnel attribute instead of making them all main attributes. Since
the tunnel code was added in this net-next cycle and still hasn't been
released we can easily nest the BRIDGE_VLANDB_ENTRY_TUNNEL_ID attribute
in BRIDGE_VLANDB_ENTRY_TUNNEL_INFO and allow for any new tunnel
attributes to be added there. In addition one positive side-effect is
that we can remove the outside vlan info flag which controlled the
operation (setlink/dellink) and move it under a new nested attribute so
user-space can specify it explicitly.
Thus the vlan tunnel format becomes:
[BRIDGE_VLANDB_ENTRY]
[BRIDGE_VLANDB_ENTRY_TUNNEL_INFO]
[BRIDGE_VLANDB_TINFO_ID]
[BRIDGE_VLANDB_TINFO_CMD]
...

Now that we have a nested tunnel info attribute we can add a separate
one for the tunnel command and require it explicitly from user-space. It
must be one of RTM_SETLINK/DELLINK. Only RTM_SETLINK requires a valid
tunnel id, DELLINK just removes it if it was set before. This allows us
to have all tunnel attributes and control in one place, thus removing
the need for an outside vlan info flag.

While discussing the new API, Roopa mentioned that we'll be adding more
tunnel attributes and options in the future, so it's better to make it a
nested attribute, since this is still in net-next we can easily change it
and nest the tunnel id attribute under BRIDGE_VLANDB_ENTRY_TUNNEL_INFO.
The new format is:
[BRIDGE_VLANDB_ENTRY]
[BRIDGE_VLANDB_ENTRY_TUNNEL_INFO]
[BRIDGE_VLANDB_TINFO_ID]
Any new tunnel attributes can be nested under
BRIDGE_VLANDB_ENTRY_TUNNEL_INFO.

This patch adds struct_ops support to the bpftool.
To recap a bit on the recent bpf_struct_ops feature on the kernel side:
It currently supports "struct tcp_congestion_ops" to be implemented
in bpf. At a high level, bpf_struct_ops is struct_ops map populated
with a number of bpf progs. bpf_struct_ops currently supports the
"struct tcp_congestion_ops". However, the bpf_struct_ops design is
generic enough that other kernel struct ops can be supported in
the future.
Although struct_ops is map+progs at a high lever, there are differences
in details. For example,
1) After registering a struct_ops, the struct_ops is held by the kernel
subsystem (e.g. tcp-cc). Thus, there is no need to pin a
struct_ops map or its progs in order to keep them around.
2) To iterate all struct_ops in a system, it iterates all maps
in type BPF_MAP_TYPE_STRUCT_OPS. BPF_MAP_TYPE_STRUCT_OPS is
the current usual filter. In the future, it may need to
filter by other struct_ops specific properties. e.g. filter by
tcp_congestion_ops or other kernel subsystem ops in the future.
3) struct_ops requires the running kernel having BTF info. That allows
more flexibility in handling other kernel structs. e.g. it can
always dump the latest bpf_map_info.
4) Also, "struct_ops" command is not intended to repeat all features
already provided by "map" or "prog". For example, if there really
is a need to pin the struct_ops map, the user can use the "map" cmd
to do that.
While the first attempt was to reuse parts from map/prog.c, it ended up
not a lot to share. The only obvious item is the map_parse_fds() but
that still requires modifications to accommodate struct_ops map specific
filtering (for the immediate and the future needs). Together with the
earlier mentioned differences, it is better to part away from map/prog.c.
The initial set of subcmds are, register, unregister, show, and dump.
For register, it registers all struct_ops maps that can be found in an
obj file. Option can be added in the future to specify a particular
struct_ops map. Also, the common bpf_tcp_cc is stateless (e.g.
bpf_cubic.c and bpf_dctcp.c). The "reuse map" feature is not
implemented in this patch and it can be considered later also.
For other subcmds, please see the man doc for details.

The kernel struct_ops obj has kernel's func ptrs implemented by bpf_progs.
The bpf prog_id is stored as the value of the func ptr for introspection
purpose. In the latter patch, a struct_ops dump subcmd will be added
to introspect these func ptrs. It is desired to print the actual bpf
prog_name instead of only printing the prog_id.
Since struct_ops is the only usecase storing prog_id in the func ptr,
this patch adds a prog_id_as_func_ptr bool (default is false) to
"struct btf_dumper" in order not to mis-interpret the ptr value
for the other existing use-cases.
While printing a func_ptr as a bpf prog_name,
this patch also prefix the bpf prog_name with the ptr's func_proto.
[ Note that it is the ptr's func_proto instead of the bpf prog's
func_proto ]
It reuses the current btf_dump_func() to obtain the ptr's func_proto
string.
Here is an example from the bpf_cubic.c:

can grab it when the request is prepared (from the original task), and
pass that in when we do the async part part of the open.

This soc has two phy's for the pcie one of them using just a different
register for settig it up but sharing all the rest of the config. Until
now we was presenting this schema as three different phy's in the device
tree using the 'phy-cells' node property to discriminate an index and
setting up a complete phy for the dual port index. This sometimes worked
properly but reconfiguring the same registers twice presents sometimes
some unstable pcie links and the ports was not properly being detected.
The problems only appears on hard resets and soft resets was properly
working. Instead of having this schema just set two phy's in the device
ree and use the 'phy-cells' property to say if the port has or not a dual
port. Doing this configuration and set up becomes easier, LOC is decreased
and the behaviour also gets deterministic with properly and stable pcie
links in both hard and soft resets.

Controls Qualcomm's SS PHY 1.0.0 implemented on various SoCs on both the
20nm and 28nm process nodes.
Based on Sriharsha Allenki's <sallenki@codeaurora.org> original code.
[bod: Removed dependency on extcon.
Switched to gpio-usb-conn to handle VBUS On/Off
Switched to usb-role-switch to bind gpio-usb-conn to DWC3]

Binding description for Qualcomm's Synopsys 1.0.0 SuperSpeed PHY. This PHY
appears in a number of SoCs on various flavors of 20nm and 28nm nodes.
This commit adds information related to the 28nm node only.
Based on Sriharsha Allenki's <sallenki@codeaurora.org> original
definitions.

Adds Qualcomm 28nm Hi-Speed USB PHY driver support. This PHY is usually
paired with Synopsys DWC3 USB controllers on Qualcomm SoCs.
The PHY can come in two flavours femtoPHY or picoPHY. This commit adds
support for the femtoPHY with the possibility of extending to the picoPHY
with additional future commits. Both PHYs are on a 28 nanometer process
node.
[bod: Updated qcom_snps_hsphy_set_mode to match new method signature
Added disjunct on mode > 0
Removed regulator_set_voltage() in favour of setting floor in dts
Removed 'snps' and from driver name
Extended commit log to mention femtoPHY and picoPHY for future
reference.]

Usually the digital and analog phys use the same reference clock,
but some platforms have two separate reference clocks for each of
them, so add another optional clock to support them.
In order to keep the clock names consistent with PHY IP's, change
the da_ref for analog phy and ref clock for digital phy.
