net: dsa: mv88e6xxx: check for mode change in port_setup_mac
The mv88e6xxx_port_setup_mac checks if the requested MAC settings are
different from the current ones, and if not, does nothing (since chaning
them requires putting the link down).
In this check it only looks if the triplet [link, speed, duplex] is
being changed.
This patch adds support to also check if the mode parameter (of type
phy_interface_t) is requested to be changed. The current mode is
computed by the ->port_link_state() method, and if it is different from
PHY_INTERFACE_MODE_NA, we check for equality with the requested mode.
In the implementations of the mv88e6250_port_link_state() method we set
the current mode to PHY_INTERFACE_MODE_NA - so the code does not check
for mode change on 6250.
In the mv88e6352_port_link_state() method, we use the cached cmode of
the port to determine the mode as phy_interface_t (and if it is not
enough, eg. for RGMII, we also look at the port control register for
RX/TX timings).

* ADIN1300 - Robust, Industrial, Low Latency 10/100/1000 Gigabit

The chips can be operated by the Generic PHY driver as well via the
standard IEEE PHY registers (0x0000 - 0x000F) which are supported by the

completely in HW, according to spec, i.e. no extra SW configuration
required.
This changeset also implements the ability to configure the chips via SW

net: phy: adin: implement PHY subsystem software reset
The ADIN PHYs supports 4 types of reset:
1. The standard PHY reset via BMCR_RESET bit in MII_BMCR reg
2. Reset via GPIO
3. Reset via reg GeSftRst (0xff0c) & reload previous pin configs
4. Reset via reg GeSftRst (0xff0c) & request new pin configs
Resets 2, 3 & 4 are almost identical, with the exception that the crystal
oscillator is available during reset for 2.
This change implements subsystem software reset via the GeSftRst and
reloading the previous pin configuration (so reset number 3).
This will also reset the PHY core regs (similar to reset 1).
Since writing bit 1 to reg GeSftRst is self-clearing, the only thing that
can be done, is to write to that register, wait a specific amount of time
(10 milliseconds should be enough) and try to read back and check if there
are no errors on read. A busy-wait-read won't work well, and may sometimes
work or not work.
In case phylib is configured to also do a reset via GPIO, the ADIN PHY may
be reset twice when the PHY device registers, but that isn't a problem,
since it's being done on boot (or PHY device register).

This is controlled via the PHY Control 1 register.
The supported modes are:
1. Manual MDI
2. Manual MDIX
3. Auto MDIX - prefer MDIX
4. Auto MDIX - prefer MDI
The phydev mdix & mdix_ctrl fields include modes 3 & 4 into a single
auto-mode. So, the default mode this driver enables is 4 when Auto-MDI mode
is used.
When detecting MDI/MDIX mode, a combination of the PHY Control 1 register
and PHY Status 1 register is used to determine the correct MDI/MDIX mode.
If Auto-MDI mode is not set, then the manual MDI/MDIX mode is returned.
If Auto-MDI mode is set, then MDIX mode is returned differs from the
preferred MDI/MDIX mode.
This covers all cases where:
1. MDI preferred & Pair01Swapped == MDIX
2. MDIX preferred & Pair01Swapped == MDI
3. MDI preferred & ! Pair01Swapped == MDIX
4. MDIX preferred & ! Pair01Swapped == MDI
The preferred MDI/MDIX mode is not configured via SW, but can be configured
via HW pins. Note that the `Pair01Swapped` is the Green-Yellow physical
pairs.

The indirect access is done via the following mechanism (for both R/W):
1. Write the address of the register in the ExtRegPtr

This mechanism is needed to manage configuration of chip settings and to

The management FW has exposed an additional method of configuring some of
the nvram options, and this makes use of that. This implementation will
come into use when newer FW files which contain configuration directives
employing this API will be provided to ethtool -f.

====================
pull-request: can-next 2019-08-14
this is a pull request for net-next/master consisting of 41 patches.
The first two patches are for the kvaser_pciefd driver: Christer Beskow
removes unnecessary code in the kvaser_pciefd_pwm_stop() function,
YueHaibing removes the unused including of <linux/version.h>.
In the next patch YueHaibing also removes the unused including of
<linux/version.h> in the f81601 driver.
In the ti_hecc driver the next 6 patches are by me and fix checkpatch
warnings. YueHaibing's patch removes an unused variable in the
ti_hecc_mailbox_read() function.
The next 6 patches all target the xilinx_can driver. Anssi Hannula's
patch fixes a chip start failure with an invalid bus. The patch by
Venkatesh Yadav Abbarapu skips an error message in case of a deferred
probe. The 3 patches by Appana Durga Kedareswara rao fix the RX and TX
path for CAN-FD frames. Srinivas Neeli's patch fixes the bit timing
calculations for CAN-FD.
The next 12 patches are by me and several checkpatch warnings in the
af_can, raw and bcm components.
Thomas Gleixner provides a patch for the bcm, which switches the timer
to HRTIMER_MODE_SOFT and removes the hrtimer_tasklet.
Then 6 more patches by me for the gw component, which fix checkpatch
warnings, followed by 2 patches by Oliver Hartkopp to add CAN-FD
support.
The vcan driver gets 3 patches by me, fixing checkpatch warnings.
And finally a patch by Andre Hartmann to fix typos in CAN's netlink
header.

Merge git://git./linux/kernel/git/bpf/bpf-next
Daniel Borkmann says:
====================
The following pull-request contains BPF updates for your *net-next* tree.
There is a small merge conflict in libbpf (Cc Andrii so he's in the loop
as well):
for (i = 1; i <= btf__get_nr_types(btf); i++) {
t = (struct btf_type *)btf__type_by_id(btf, i);
if (!has_datasec && btf_is_var(t)) {
/* replace VAR with INT */
t->info = BTF_INFO_ENC(BTF_KIND_INT, 0, 0);
<<<<<<< HEAD
/*
* using size = 1 is the safest choice, 4 will be too
* big and cause kernel BTF validation failure if
* original variable took less than 4 bytes
*/
t->size = 1;
*(int *)(t+1) = BTF_INT_ENC(0, 0, 8);
} else if (!has_datasec && kind == BTF_KIND_DATASEC) {
=======
t->size = sizeof(int);
*(int *)(t + 1) = BTF_INT_ENC(0, 0, 32);

/* replace DATASEC with STRUCT */
Conflict is between the two commits
1d4126c4e119 ("libbpf: sanitize VAR to
conservative 1-byte INT") and
b03bc6853c0e ("libbpf: convert libbpf code to
use new btf helpers"), so we need to pick the sanitation fixup as well as
use the new btf_is_datasec() helper and the whitespace cleanup. Looks like
the following:
[...]
if (!has_datasec && btf_is_var(t)) {
/* replace VAR with INT */
t->info = BTF_INFO_ENC(BTF_KIND_INT, 0, 0);
/*
* using size = 1 is the safest choice, 4 will be too
* big and cause kernel BTF validation failure if
* original variable took less than 4 bytes
*/
t->size = 1;
*(int *)(t + 1) = BTF_INT_ENC(0, 0, 8);
} else if (!has_datasec && btf_is_datasec(t)) {
/* replace DATASEC with STRUCT */
[...]
The main changes are:
1) Addition of core parts of compile once - run everywhere (co-re) effort,
that is, relocation of fields offsets in libbpf as well as exposure of
kernel's own BTF via sysfs and loading through libbpf, from Andrii.
More info on co-re: http://vger.kernel.org/bpfconf2019.html#session-2
and http://vger.kernel.org/lpc-bpf2018.html#session-2
2) Enable passing input flags to the BPF flow dissector to customize parsing
and allowing it to stop early similar to the C based one, from Stanislav.
3) Add a BPF helper function that allows generating SYN cookies from XDP and
tc BPF, from Petar.
4) Add devmap hash-based map type for more flexibility in device lookup for
redirects, from Toke.
5) Improvements to XDP forwarding sample code now utilizing recently enabled
devmap lookups, from Jesper.
6) Add support for reporting the effective cgroup progs in bpftool, from Jakub
and Takshak.
7) Fix reading kernel config from bpftool via /proc/config.gz, from Peter.
8) Fix AF_XDP umem pages mapping for 32 bit architectures, from Ivan.
9) Follow-up to add two more BPF loop tests for the selftest suite, from Alexei.
10) Add perf event output helper also for other skb-based program types, from Allan.
11) Fix a co-re related compilation error in selftests, from Yonghong.

Patch #1 is a follow-up patch to rename /sys/kernel/btf/kernel into

can: gw: add support for CAN FD frames
Introduce CAN FD support which needs an extension of the netlink API to
pass CAN FD type content to the kernel which has a different size to
Classic CAN. Additionally the struct canfd_frame has a new 'flags' element
that can now be modified with can-gw.
The new CGW_FLAGS_CAN_FD option flag defines whether the routing job
handles Classic CAN or CAN FD frames. This setting is very strict at
reception time and enables the new possibilities, e.g. CGW_FDMOD_* and
modifying the flags element of struct canfd_frame, only when
CGW_FLAGS_CAN_FD is set.
