This change adds support for configuring these modes via the device

For RGMII with internal delays (modes RGMII_ID,RGMII_TXID, RGMII_RXID),

net: phy: adin: add {write,read}_mmd hooks
Both ADIN1200 & ADIN1300 support Clause 45 access for some registers.
The Extended Management Interface (EMI) registers are accessible via both
Clause 45 (at register MDIO_MMD_VEND1) and using Clause 22.
The Clause 22 access for MMD regs differs from the standard one defined by
802.3. The ADIN PHYs use registers ExtRegPtr (0x0010) and ExtRegData
(0x0011) to access Clause 45 & EMI registers.
The indirect access is done via the following mechanism (for both R/W):
1. Write the address of the register in the ExtRegPtr
2. Read/write the value of the register via reg ExtRegData
This mechanism is needed to manage configuration of chip settings and to
access EEE registers via Clause 22.
Since Clause 45 access will likely never be used, it is not implemented via
this hook.

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

The 2 chips are register compatible with one another. The main difference
being that ADIN1200 doesn't operate in gigabit mode.
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.

net: phy: let phy_speed_down/up support speeds >1Gbps
So far phy_speed_down/up can be used up to 1Gbps only. Remove this
restriction by using new helper __phy_speed_down. New member adv_old
in struct phy_device is used by phy_speed_up to restore the advertised
modes before calling phy_speed_down. Don't simply advertise what is
supported because a user may have intentionally removed modes from
advertisement.

phy_speed_down_core provides most of the functionality for
phy_speed_down. It makes use of new helper phy_resolve_min_speed that is
based on the sorting of the settings[] array. In certain cases it may be

====================
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

t->size = 1;

/* 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.

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.

can: xilinx_can: xcan_chip_start(): fix failure with invalid bus
Currently the xilinx_can xcan_chip_start() function, called from
.ndo_open() and via CAN_MODE_START (bus-off restart), waits for the SR
register to show the wanted operating state, with a 1 sec timeout.
However, that register bit will only be set once the HW has observed 11
consecutive recessive bits (BusIdle) on the bus.
If the bus will not see the 11 bits (e.g. it is stuck dominant), the
function will timeout and return an error. If this was done as part of a
scheduled restart from bus-off, the interface will stay in bus-off state
forever even if the bus recovers later.
According to M_CAN and FLEXCAN documentation they also wait for 11
consecutive recessive bits, but their drivers do not seem to wait for
that.
To make the behavior consistent, modify xilinx_can to also not wait for
the synchronization to complete.
The only way for users to know for sure that the bus has been joined
successfully is to see successfully received or transmitted frames. That
does not seem optimal, but it is consistent with other drivers and we
should have a properly working restart-ms with xilinx_can.
