      net: phy: make of_set_phy_supported work with genphy driver · de906af1
      由 Sascha Hauer 提交于 
      of_set_phy_supported allows overwiting hardware capabilities of
a phy with values from the devicetree. of_set_phy_supported is
called right after phy_device_register in the assumption that
phy_probe is called from phy_device_register and the features
of the phy are already initialized. For the genphy driver this
is not true, here phy_probe is called later during phy_connect
time. phy_probe will then overwrite all settings done from
of_set_phy_supported
Fix this by moving of_set_phy_supported to the core phy code
and calling it from phy_probe.

      net: phy: genphy: Allow overwriting features · c242a472
      由 Sascha Hauer 提交于 
      of_set_phy_supported allows overwiting hardware capabilities of
a phy with values from the devicetree. This does not work with
the genphy driver though because the genphys config_init function
will overwrite all values adjusted by of_set_phy_supported. Fix
this by initialising the genphy features in the phy_driver struct
and in config_init just limit the features to the ones the hardware
can actually support. The resulting features are a subset of the
devicetree specified features and the hardware features.

      net: phy: Don't call phy_resume if phy_init_hw failed · b394745d
      由 Guenter Roeck 提交于 
      After the call to phy_init_hw failed in phy_attach_direct, phy_detach is called
to detach the phy device from its network device. If the attached driver is a
generic phy driver, this also detaches the driver. Subsequently phy_resume
is called, which assumes without checking that a driver is attached to the
device. This will result in a crash such as

      net: ptp: move PTP classifier in its own file · 408eccce
      由 Daniel Borkmann 提交于 
      This commit fixes a build error reported by Fengguang, that is
triggered when CONFIG_NETWORK_PHY_TIMESTAMPING is not set:

  ERROR: "ptp_classify_raw" [drivers/net/ethernet/oki-semi/pch_gbe/pch_gbe.ko] undefined!

The fix is to introduce its own file for the PTP BPF classifier,
so that PTP_1588_CLOCK and/or NETWORK_PHY_TIMESTAMPING can select
it independently from each other. IXP4xx driver on ARM needs to
select it as well since it does not seem to select PTP_1588_CLOCK
or similar that would pull it in automatically.

This also allows for hiding all of the internals of the BPF PTP
program inside that file, and only exporting relevant API bits
to drivers.

This patch also adds a kdoc documentation of ptp_classify_raw()
API to make it clear that it can return PTP_CLASS_* defines. Also,
the BPF program has been translated into bpf_asm code, so that it
can be more easily read and altered (extensively documented in [1]).

In the kernel tree under tools/net/ we have bpf_asm and bpf_dbg
tools, so the commented program can simply be translated via
`./bpf_asm -c prog` where prog is a file that contains the
commented code. This makes it easily readable/verifiable and when
there's a need to change something, jump offsets etc do not need
to be replaced manually which can be very error prone. Instead,
a newly translated version via bpf_asm can simply replace the old
code. I have checked opcode diffs before/after and it's the very
same filter.
