The main changes are:
1) Addition of BPF trampoline which works as a bridge between kernel functions,
BPF programs and other BPF programs along with two new use cases: i) fentry/fexit
BPF programs for tracing with practically zero overhead to call into BPF (as
opposed to k[ret]probes) and ii) attachment of the former to networking related
programs to see input/output of networking programs (covering xdpdump use case),
from Alexei Starovoitov.
2) BPF array map mmap support and use in libbpf for global data maps; also a big
batch of libbpf improvements, among others, support for reading bitfields in a
relocatable manner (via libbpf's CO-RE helper API), from Andrii Nakryiko.
3) Extend s390x JIT with usage of relative long jumps and loads in order to lift
the current 64/512k size limits on JITed BPF programs there, from Ilya Leoshkevich.
4) Add BPF audit support and emit messages upon successful prog load and unload in
order to have a timeline of events, from Daniel Borkmann and Jiri Olsa.
5) Extension to libbpf and xdpsock sample programs to demo the shared umem mode
(XDP_SHARED_UMEM) as well as RX-only and TX-only sockets, from Magnus Karlsson.
6) Several follow-up bug fixes for libbpf's auto-pinning code and a new API
call named bpf_get_link_xdp_info() for retrieving the full set of prog
IDs attached to XDP, from Toke Høiland-Jørgensen.
7) Add BTF support for array of int, array of struct and multidimensional arrays
and enable it for skb->cb[] access in kfree_skb test, from Martin KaFai Lau.
8) Fix AF_XDP by using the correct number of channels from ethtool, from Luigi Rizzo.
9) Two fixes for BPF selftest to get rid of a hang in test_tc_tunnel and to avoid
xdping to be run as standalone, from Jiri Benc.
10) Various BPF selftest fixes when run with latest LLVM trunk, from Yonghong Song.
11) Fix a memory leak in BPF fentry test run data, from Colin Ian King.
12) Various smaller misc cleanups and improvements mostly all over BPF selftests and
samples, from Daniel T. Lee, Andre Guedes, Anders Roxell, Mao Wenan, Yue Haibing.

Commit 823eb2a3c4c7 ("PTP: add support for one-shot output") introduced
a new flag for the PTP periodic output request ioctl. This flag is not
currently supported by any driver.
Fix all drivers which implement the periodic output request ioctl to
explicitly reject any request with flags they do not understand. This
ensures that the driver does not accidentally misinterpret the
PTP_PEROUT_ONE_SHOT flag, or any new flag introduced in the future.
This is important for forward compatibility: if a new flag is
introduced, the driver should reject requests to enable the flag until
the driver has actually been modified to support the flag in question.

The phy_init_hw() function may reset the PHY to a configuration
that does not match manual network settings stored in the phydev
structure. If the phy state machine is polled rather than event
driven this can create a timing hazard where the phy state machine
might alter the settings stored in the phydev structure from the
value read from the BMCR.
This commit follows invocations of phy_init_hw() by the bcmgenet
driver with invocations of the genphy_config_aneg() function to
ensure that the BMCR is written to match the settings held in the
phydev structure. This prevents the risk of manual settings being
accidentally altered.

This reverts commit 1f515486275a08a17a2c806b844cca18f7de5b34.
This commit improved the chances of the umac resetting cleanly by
ensuring that the PHY was restored to its normal operation prior
to resetting the umac. However, there were still cases when the
PHY might not be driving a Tx clock to the umac during this window
(e.g. when the PHY detects no link).
The previous commit now ensures that the unimac receives clocks
from the MAC during its reset window so this commit is no longer
needed. This commit also has an unintended negative impact on the
MDIO performance of the UniMAC MDIO interface because it is used
before the MDIO interrupts are reenabled, so it should be removed.

As noted in commit 28c2d1a7a0bf ("net: bcmgenet: enable loopback
during UniMAC sw_reset") the UniMAC must be clocked while sw_reset
is asserted for its state machines to reset cleanly.
The transmit and receive clocks used by the UniMAC are derived from
the signals used on its PHY interface. The bcmgenet MAC can be
configured to work with different PHY interfaces including MII,
GMII, RGMII, and Reverse MII on internal and external interfaces.
Unfortunately for the UniMAC, when configured for MII the Tx clock
is always driven from the PHY which places it outside of the direct
control of the MAC.
The earlier commit enabled a local loopback mode within the UniMAC
so that the receive clock would be derived from the transmit clock
which addressed the observed issue with an external GPHY disabling
it's Rx clock. However, when a Tx clock is not available this
loopback is insufficient.
This commit implements a workaround that leverages the fact that
the MAC can reliably generate all of its necessary clocking by
enterring the external GPHY RGMII interface mode with the UniMAC in
local loopback during the sw_reset interval. Unfortunately, this
has the undesirable side efect of the RGMII GTXCLK signal being
driven during the same window.
In most configurations this is a benign side effect as the signal
is either not routed to a pin or is already expected to drive the
pin. The one exception is when an external MII PHY is expected to
drive the same pin with its TX_CLK output creating output driver
contention.
This commit exploits the IEEE 802.3 clause 22 standard defined
isolate mode to force an external MII PHY to present a high
impedance on its TX_CLK output during the window to prevent any
contention at the pin.
The MII interface is used internally with the 40nm internal EPHY
which agressively disables its clocks for power savings leading to
incomplete resets of the UniMAC and many instabilities observed
over the years. The workaround of this commit is expected to put
an end to those problems.

Before this change of_get_phy_mode() returned an enum,
phy_interface_t. On error, -ENODEV etc, is returned. If the result of
the function is stored in a variable of type phy_interface_t, and the
compiler has decided to represent this as an unsigned int, comparision
with -ENODEV etc, is a signed vs unsigned comparision.
Fix this problem by changing the API. Make the function return an
error, or 0 on success, and pass a pointer, of type phy_interface_t,
where the phy mode should be stored.

We call bnxt_ulp_stop() to notify the RDMA driver that some error or
imminent reset is about to happen. After that we always call
some variants of bnxt_close().
In the next patch, we will integrate the recently added error
recovery with the RDMA driver. In response to ulp_stop, the
RDMA driver may free MSIX vectors and that will also trigger
bnxt_close(). To avoid bnxt_close() from being called twice,
we set a new flag after ulp_stop is called. If the RDMA driver
frees MSIX vectors while the new flag is set, we will not call
bnxt_close(), knowing that it will happen in due course.
With this change, we must make sure that the bnxt_close() call
after ulp_stop will reset IRQ. Modify bnxt_reset_task()
accordingly if we call ulp_stop.

The decap (VXLAN tunnel) flow rules are not getting offloaded with
upstream kernel. This is because TC block callback infrastructure has
been updated to use indirect callbacks to get offloaded rules from
other higher level devices (such as tunnels), instead of ndo_setup_tc().
Since the decap rules are applied to the tunnel devices (e.g, vxlan_sys),
the driver should register for indirect TC callback with tunnel devices
to get the rules for offloading. This patch updates the driver to
register and process indirect TC block callbacks from VXLAN tunnels.

Driver supports 2 types of core dumps.
1. Live dump - Firmware dump when system is up and running.
2. Crash dump - Dump which is collected during firmware crash
that can be retrieved after recovery.
Crash dump is currently supported only on specific 58800 chips
which can be retrieved using OP-TEE API only, as firmware cannot
access this region directly.
User needs to set the dump flag using following command before
initiating the dump collection:
$ ethtool -W|--set-dump eth0 N
Where N is "0" for live dump and "1" for crash dump
Command to collect the dump after setting the flag:
$ ethtool -w eth0 data Filename
v3: Modify set_dump to support even when CONFIG_TEE_BNXT_FW=n.
Also change log message to netdev_info().

With the recently added error recovery logic, the device may already
be disabled if the firmware recovery is unsuccessful. In
bnxt_remove_one(), check that the device is still enabled first
before calling pci_disable_device().

When firmware indicates that driver needs to invoke firmware reset
which is common for both error recovery and live firmware reset path,
driver needs a different time to wait before polling for firmware
readiness.
Modify the wait time to fw_reset_min_dsecs, which is initialised to
correct timeout for error recovery and firmware reset.

The current code does not do endian swapping between the devlink
parameter and the internal NVRAM representation. Define a union to
represent the little endian NVRAM data and add 2 helper functions to
copy to and from the NVRAM data with the proper byte swapping.

The current code that rounds up the NVRAM parameter bit size to the next
byte size for the devlink parameter is not always correct. The MSIX
devlink parameters are 4 bytes and we don't get the correct size
using this method.
Fix it by adding a new dl_num_bytes member to the bnxt_dl_nvm_param
structure which statically provides bytesize information according
to the devlink parameter type definition.
