For sync we send a marker cmd every <defined throughout debugfs> seconds.
The trigger for getting gp2 clock values from the FW is set by
writing to debugfs a periodic time in seconds,
if value zero is written, only one request would be sent
and the timer would be canceled.
Also added a small infrastructure for debugfs runtime code.

The way p2p NoA is forced in SCM (used for WFA tests)
is by setting a quota < 100% (simulating DCM).
A test-mode command is used for setting the NoA params.
In that case, force quota update or nothing will happen
if there was no significant change in the quota
at that exact point (which is likely to be the case).

Generate rules for the NFP to encapsulate packets in Geneve tunnels. Move
the vxlan action code to generic udp tunnel actions and use core code for
both vxlan and Geneve.
Only support outputting to well known port 6081. Setting tunnel options
is not supported yet.
Only attempt to offload if the fw supports Geneve.

Compile Geneve match fields for offloading to the NFP. The addition of
Geneve overflows the 8 bit key_layer field, so apply extended metadata to
the match cmsg allowing up to 32 more key_layer fields.
Rather than adding new Geneve blocks, move the vxlan code to generic ipv4
udp tunnel structs and use these for both vxlan and Geneve.
Matches are only supported when specifically mentioning well known port
6081. Geneve tunnel options are not yet included in the match.
Only offload Geneve if the fw supports it - include check for this.

The tunnel dest IP is required for separate offload to the NFP. It is
already verified that a dest IP must be present and must be an exact
match in the flower rule. Therefore, we can just extract the IP from the
generated offload rule and remove the unused mask variable. The function
is then no longer required to return the IP separately.
Because tun_dst is localised to tunnel matches, move the declaration to
the tunnel if branch.

The PHY performs just as well when left in its default configuration and
it makes senses because this poke gets reset just after init.
According to the documentation, all registers in the Analog/DSP bank are
reset when there is a mode switch from 10BT to 100BT. The bank is also
reset on power down and soft reset, so we will never see the value which
may have been set by the bootloader.
In the end, we have used the default configuration so far and there is no
reason to change now. Remove CONFIG_A6 poke to make this clear.

Daniel Borkmann says:
====================
pull-request: bpf-next 2017-12-18
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Allow arbitrary function calls from one BPF function to another BPF function.
As of today when writing BPF programs, __always_inline had to be used in
the BPF C programs for all functions, unnecessarily causing LLVM to inflate
code size. Handle this more naturally with support for BPF to BPF calls
such that this __always_inline restriction can be overcome. As a result,
it allows for better optimized code and finally enables to introduce core
BPF libraries in the future that can be reused out of different projects.
x86 and arm64 JIT support was added as well, from Alexei.
2) Add infrastructure for tagging functions as error injectable and allow for
BPF to return arbitrary error values when BPF is attached via kprobes on
those. This way of injecting errors generically eases testing and debugging
without having to recompile or restart the kernel. Tags for opting-in for
this facility are added with BPF_ALLOW_ERROR_INJECTION(), from Josef.
3) For BPF offload via nfp JIT, add support for bpf_xdp_adjust_head() helper
call for XDP programs. First part of this work adds handling of BPF
capabilities included in the firmware, and the later patches add support
to the nfp verifier part and JIT as well as some small optimizations,
from Jakub.
4) The bpftool now also gets support for basic cgroup BPF operations such
as attaching, detaching and listing current BPF programs. As a requirement
for the attach part, bpftool can now also load object files through
'bpftool prog load'. This reuses libbpf which we have in the kernel tree
as well. bpftool-cgroup man page is added along with it, from Roman.
5) Back then commit e87c6bc3852b ("bpf: permit multiple bpf attachments for
a single perf event") added support for attaching multiple BPF programs
to a single perf event. Given they are configured through perf's ioctl()
interface, the interface has been extended with a PERF_EVENT_IOC_QUERY_BPF
command in this work in order to return an array of one or multiple BPF
prog ids that are currently attached, from Yonghong.
6) Various minor fixes and cleanups to the bpftool's Makefile as well
as a new 'uninstall' and 'doc-uninstall' target for removing bpftool
itself or prior installed documentation related to it, from Quentin.
7) Add CONFIG_CGROUP_BPF=y to the BPF kernel selftest config file which is
required for the test_dev_cgroup test case to run, from Naresh.
8) Fix reporting of XDP prog_flags for nfp driver, from Jakub.
9) Fix libbpf's exit code from the Makefile when libelf was not found in
the system, also from Jakub.

Unlike the various of_* routines to fetch properties, fwnode_* routines can
have an early check against a NULL fwnode_handle reference which makes them
return -EINVAL (see fwnode_call_int_op), thus making it virtually impossible to
differentiate what type of error is going on.
Have an early check in phylink_register_sfp() so we can keep proceeding with
the initialization, there is not much we can do without a valid fwnode_handle
except return early and treat this similarly to -ENOENT.

It has been reported that the dummy byte we add to avoid
ZLPs can be forwarded by the modem to the PGW/GGSN, and that
some operators will drop the connection if this happens.
In theory, QMI devices are based on CDC ECM and should as such
both support ZLPs and silently ignore the dummy byte. The latter
assumption failed. Let's test out the first.
