The TSU_QTAG0/1 registers found in the Gigabit Ether controllers actually
have the same long name as the TSU_QTAGM0/1 registers in the early Ether
controllers: Qtag Addition/Deletion Set Register (Port 0/1 to 1/0); thus
there's no need to make a difference in sh_eth_tsu_init() between those
controllers. Unfortunately, we can't just remove TSU_QTAG0/1 from the
register *enum* because that would break the ethtool register dump...

On hardware which supports timestamping all packets, the timestamps are
recorded in the packet buffer, and the driver no longer uses or reads
the registers. This makes the logic for checking and clearing Rx
timestamp hangs meaningless.
If we run the ixgbe_ptp_rx_hang() function in this case, then the driver
will continuously spam the log output with "Clearing Rx timestamp hang".
These messages are spurious, and confusing to end users.
The original code in commit a9763f3cb5 ("ixgbe: Update PTP to support
X550EM_x devices", 2015-12-03) did have a flag PTP_RX_TIMESTAMP_IN_REGISTER
which was intended to be used to avoid the Rx timestamp hang check,
however it did not actually check the flag before calling the function.
Do so now in order to stop the checks and prevent the spurious log
messages.

mv88e6xxx: Poll when no interrupt defined
Not all boards using the mv88e6xxx switches have the interrupt output

register, which is more efficient than having phylib do it. And it
enables other switch interrupts to be services.

Not all boards have the interrupt output from the switch connected to
a GPIO line. In such cases, phylib has to poll the internal PHYs,
rather than receive an interrupt when there is a change in the link
state. phylib polls once per second, and per PHY reads around 4
words. With a switch typically having 4 internal PHYs, this means 16
MDIO transactions per second.
Rather than performing this phylib level polling, have the driver poll
the interrupt status register. If the status register indicates an
interrupt condition processing of interrupts in the same way as if a
GPIO was used.
Polling 10 times a second places less load on the MDIO bus. But rather
than taking on average 0.5s to detect a link change, it takes less
than 0.05s. Additionally, other interrupts, such as the watchdog, ATU
and VTU violations will be reported.

Up until now we only allowed VLAN devices to be put in a VLAN-unaware
bridge, but some users need the ability to enslave physical ports as
well.
This is achieved by mapping the port and VID 1 to the bridge's vFID,
instead of the port and the VID used by the VLAN device.
The above is valid because as long as the port is not enslaved to a
bridge, VID 1 is guaranteed to be configured as PVID and egress
untagged.

pull-request: bpf-next 2018-02-26
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Various improvements for BPF kselftests: i) skip unprivileged tests
when kernel.unprivileged_bpf_disabled sysctl knob is set, ii) count
the number of skipped tests from unprivileged, iii) when a test case
had an unexpected error then print the actual but also the unexpected
one for better comparison, from Joe.
2) Add a sample program for collecting CPU state statistics with regards
to how long the CPU resides in cstate and pstate levels. Based on
cpu_idle and cpu_frequency trace points, from Leo.
3) Various x64 BPF JIT optimizations to further shrink the generated
image size in order to make it more icache friendly. When tested on
the Cilium generated programs, image size reduced by approx 4-5% in
best case mainly due to how LLVM emits unsigned 32 bit constants,
from Daniel.
4) Improvements and fixes on the BPF sockmap sample programs: i) fix
the sockmap's Makefile to include nlattr.o for libbpf, ii) detach
the sock ops programs from the cgroup before exit, from Prashant.
5) Avoid including xdp.h in filter.h by just forward declaring the
struct xdp_rxq_info in filter.h, from Jesper.
6) Fix the BPF kselftests Makefile for cgroup_helpers.c by only declaring
it a dependency for test_dev_cgroup.c but not every other test case
where it is not needed, from Jesper.
7) Adjust rlimit RLIMIT_MEMLOCK for test_tcpbpf_user selftest since the
default is insufficient for creating the 'global_map' used in the
corresponding BPF program, from Yonghong.
8) Likewise, for the xdp_redirect sample, Tushar ran into the same when
invoking xdp_redirect and xdp_monitor at the same time, therefore
in order to have the sample generically work bump the limit here,

CPU is active when have running tasks on it and CPUFreq governor can
select different operating points (OPP) according to different workload;
we use 'pstate' to present CPU state which have running tasks with one
specific OPP. On the other hand, CPU is idle which only idle task on
it, CPUIdle governor can select one specific idle state to power off
hardware logics; we use 'cstate' to present CPU idle state.
Based on trace events 'cpu_idle' and 'cpu_frequency' we can accomplish
the duration statistics for every state. Every time when CPU enters
into or exits from idle states, the trace event 'cpu_idle' is recorded;
trace event 'cpu_frequency' records the event for CPU OPP changing, so
it's easily to know how long time the CPU stays in the specified OPP,
and the CPU must be not in any idle state.
This patch is to utilize the mentioned trace events for pstate and
cstate statistics. To achieve more accurate profiling data, the program
uses below sequence to insure CPU running/idle time aren't missed:
- Before profiling the user space program wakes up all CPUs for once, so
can avoid to missing account time for CPU staying in idle state for
long time; the program forces to set 'scaling_max_freq' to lowest
frequency and then restore 'scaling_max_freq' to highest frequency,
this can ensure the frequency to be set to lowest frequency and later
after start to run workload the frequency can be easily to be changed
to higher frequency;
- User space program reads map data and update statistics for every 5s,
so this is same with other sample bpf programs for avoiding big
overload introduced by bpf program self;
- When send signal to terminate program, the signal handler wakes up
all CPUs, set lowest frequency and restore highest frequency to
'scaling_max_freq'; this is exactly same with the first step so
avoid to missing account CPU pstate and cstate time during last
stage. Finally it reports the latest statistics.
The program has been tested on Hikey board with octa CA53 CPUs, below
is one example for statistics result, the format mainly follows up
Jesper Dangaard Brouer suggestion.
Jesper reminds to 'get printf to pretty print with thousands separators
use %' and setlocale(LC_NUMERIC, "en_US")', tried three different arm64
GCC toolchains (5.4.0 20160609, 6.2.1 20161016, 6.3.0 20170516) but all
of them cannot support printf flag character %' on arm64 platform, so go
back print number without grouping mode.

BPF instructions for loading unsigned 32-bit immediates into a
register. Given we cannot change the current/stable LLVM versions
that are already out there, lets optimize this case such that the
JIT prefers to emit 'mov %eax, imm32' over 'movabsq %rax, imm64'
whenever suitable in order to reduce the image size by 4-5 bytes per
such load in the typical case, reducing image size on some of the

These are mostly fixes for problems with merge window code. In
addition we have one doc update (alua) and two dead code removals
(aiclib and octogon) a spurious assignment removal (csiostor) and a
performance improvement for storvsc involving better interrupt
spreading and increasing the command per lun handling.

For ages iproute2 has used `struct rtmsg` as the ancillary header for
FIB rules and in the process set the protocol value to RTPROT_BOOT.
Until ca56209a66 ("net: Allow a rule to track originating protocol")
the kernel rules code ignored the protocol value sent from userspace
and always returned 0 in notifications. To avoid incompatibility with
existing iproute2, send the protocol as a new attribute.
Fixes: cac56209a6 ("net: Allow a rule to track originating protocol")

When in switchdev mode, there is no need to do self loopback checks
as we can't receive those packets, we insert steering rules to the
eswitch that make sure packets can't be looped back.

Up until this point it wasn't possible to activate IB representors
when switching to switchdev mode, remove this limitation.
We trigger reload of the PF IB interface in order to make sure that
already allocated resources are invalid and new resources will be opened
correctly with all the limitations of switchdev mode applied (only raw
packet capabilities, without RoCE). We also move the remove/add to a
place where the E-Switch mode is set/unset to better control when to
trigger this action, this will allow the IB side to start in the correct
mode.
For better code reuse, create a function which reloads an interface and
export it.

This commit adds full support for IB representor:
1) Representors profile, We add two new profiles:
nic_rep_profile - This profile will be used to create an IB device that
represents the PF/UPLINK.
rep_profile - This profile will be used to create an IB device that
represents VFs. Each VF will be its own representor.
2) Proper load/unload callbacks, Those are called by the E-Switch when
moving to/from switchdev mode.
3) Different flow DB handling for when we in switchdev mode.

When enabling many VFs and switching to switchdev mode, the total amount
of mkeys we try to allocate when loading representors is very large and
may cause timeouts on allocations, the same issues was observed on VFs
and we employ the same fix that was done for them. We avoid allocating
the full MR cache on load but still allow it to be manipulated once the
IB device is loaded.

Currently in switchdev mode we allow only for raw packet QPs.
Expose the right capabilities and set the gid table length to 0, also
make sure we don't try to enable RoCE, so split the function
to enable RoCE so representors can enable only the notifier needed for
net device events.
