This is a follow-up to the discussion in [0]. It seems to me that
at least the IP version used on Amlogic SoC's sometimes has a problem
if register MAC_CTRL_REG is written whilst the chip is still processing
a previous write. But that's just a guess.
Adding a delay between two writes to this register helps, but we can
also simply omit the offending second write. This patch uses the second
approach and is based on a suggestion from Qi Duan.
Benefit of this approach is that we can save few register writes, also
on not affected chip versions.

intel_eth_pci_remove()
Commit 09f012e64e4b ("stmmac: intel: Fix clock handling on error and remove
paths") removed this clk_disable_unprepare()
This was partly revert by commit ac322f86b56c ("net: stmmac: Fix clock
handling on remove path") which removed this clk_disable_unprepare()
because:
"
While unloading the dwmac-intel driver, clk_disable_unprepare() is
being called twice in stmmac_dvr_remove() and
intel_eth_pci_remove(). This causes kernel panic on the second call.
"
However later on, commit 5ec55823438e8 ("net: stmmac: add clocks management
for gmac driver") has updated stmmac_dvr_remove() which do not call
clk_disable_unprepare() anymore.
So this call should now be called from intel_eth_pci_remove().

MTU by releasing and opening the stmmac driver to set the new MTU.
Also call the set_filter function to correctly init the port.

Current stmmac driver will prepare/enable ptp_ref clock in
stmmac_init_tstamp_counter().
The stmmac_pltfr_noirq_suspend will disable it once in suspend flow.
But in resume flow,
stmmac_pltfr_noirq_resume --> stmmac_init_tstamp_counter
stmmac_resume --> stmmac_hw_setup --> stmmac_init_ptp --> stmmac_init_tstamp_counter
ptp_ref clock reference counter increases twice, which leads to unbalance
ptp clock when resume back.
Move ptp_ref clock prepare/enable out of stmmac_init_tstamp_counter to fix it.

There is a long-standing issue with the Synopsys DWC Ethernet driver
for Tegra194 where random system crashes have been observed [0]. The
problem occurs when the split header feature is enabled in the stmmac
driver. In the bad case, a larger than expected buffer length is
received and causes the calculation of the total buffer length to
overflow. This results in a very large buffer length that causes the
kernel to crash. Why this larger buffer length is received is not clear,
however, the feedback from the NVIDIA design team is that the split
header feature is not supported for Tegra194. Therefore, disable split
header support for Tegra194 to prevent these random crashes from
occurring.

imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed
It's perfectly fine, and the device is successfully (and silently, as
far as the console goes) probed later.
Use dev_err_probe() instead, which will demote these messages to debug
level (thus removing the alarming messages from the console) when the
error is -EPROBE_DEFER, and also has the advantage of including the
error code if/when it happens to be something other than -EPROBE_DEFER.

Based on DesignWare Ethernet QoS datasheet, we are seeing the limitation
of Split Header (SPH) feature is not supported for Ipv4 fragmented packet.
This SPH limitation will cause ping failure when the packets size exceed
the MTU size. For example, the issue happens once the basic ping packet
size is larger than the configured MTU size and the data is lost inside
the fragmented packet, replaced by zeros/corrupted values, and leads to
ping fail.
So, disable the Split Header for Intel platforms.
v2: Add fixes tag in commit message.

pull-request: bpf-next 2022-04-27
We've added 85 non-merge commits during the last 18 day(s) which contain
a total of 163 files changed, 4499 insertions(+), 1521 deletions(-).
The main changes are:
1) Teach libbpf to enhance BPF verifier log with human-readable and relevant
information about failed CO-RE relocations, from Andrii Nakryiko.
2) Add typed pointer support in BPF maps and enable it for unreferenced pointers
(via probe read) and referenced ones that can be passed to in-kernel helpers,
from Kumar Kartikeya Dwivedi.
3) Improve xsk to break NAPI loop when rx queue gets full to allow for forward
progress to consume descriptors, from Maciej Fijalkowski & Björn Töpel.
4) Fix a small RCU read-side race in BPF_PROG_RUN routines which dereferenced
the effective prog array before the rcu_read_lock, from Stanislav Fomichev.
5) Implement BPF atomic operations for RV64 JIT, and add libbpf parsing logic
for USDT arguments under riscv{32,64}, from Pu Lehui.
6) Implement libbpf parsing of USDT arguments under aarch64, from Alan Maguire.
7) Enable bpftool build for musl and remove nftw with FTW_ACTIONRETVAL usage
so it can be shipped under Alpine which is musl-based, from Dominique Martinet.
8) Clean up {sk,task,inode} local storage trace RCU handling as they do not
need to use call_rcu_tasks_trace() barrier, from KP Singh.
9) Improve libbpf API documentation and fix error return handling of various
API functions, from Grant Seltzer.
10) Enlarge offset check for bpf_skb_{load,store}_bytes() helpers given data
length of frags + frag_list may surpass old offset limit, from Liu Jian.
11) Various improvements to prog_tests in area of logging, test execution
and by-name subtest selection, from Mykola Lysenko.
12) Simplify map_btf_id generation for all map types by moving this process
to build time with help of resolve_btfids infra, from Menglong Dong.
13) Fix a libbpf bug in probing when falling back to legacy bpf_probe_read*()
helpers; the probing caused always to use old helpers, from Runqing Yang.
14) Add support for ARCompact and ARCv2 platforms for libbpf's PT_REGS
tracing macros, from Vladimir Isaev.
15) Cleanup BPF selftests to remove old & unneeded rlimit code given kernel
switched to memcg-based memory accouting a while ago, from Yafang Shao.
16) Refactor of BPF sysctl handlers to move them to BPF core, from Yan Zhu.
17) Fix BPF selftests in two occasions to work around regressions caused by latest
LLVM to unblock CI until their fixes are worked out, from Yonghong Song.
18) Misc cleanups all over the place, from various others.

I made a mistake with the commit a6aaa0032424 ("net: ethernet: stmmac:
fix altr_tse_pcs function when using a fixed-link"). I should have
tested against both scenario of having a SGMII interface and one
without.
Without the SGMII PCS TSE adpater, the sgmii_adapter_base address is
NULL, thus a write to this address will fail.

The init_systime() may be invoked in atomic state. We have observed the
following call trace when running "phc_ctl /dev/ptp0 set" on a Intel
Agilex board.

So we should use readl_poll_timeout_atomic() here instead of
readl_poll_timeout().
Also adjust the delay time to 10us to fix a "__bad_udelay" build error
reported by "kernel test robot <lkp@intel.com>". I have tested this on
Intel Agilex and NXP S32G boards, there is no delay needed at all.
So the 10us delay should be long enough for most cases.

Currently, when debugging AF_XDP workloads, one can correlate the -ENXIO
return code as the case that XSK is not in the bound state. Returning
same code from ndo_xsk_wakeup can be misleading and simply makes it
harder to follow what is going on.
Change ENXIOs in stmmac's ndo_xsk_wakeup() implementation to EINVALs, so
that when probing it is clear that something is wrong on the driver
side, not the xsk_{recv,send}msg.
There is a -ENETDOWN that can happen from both kernel/driver sides
though, but I don't have a correct replacement for this on one of the
sides, so let's keep it that way.
