net phy: Check for aneg completion before setting state to PHY_RUNNING

2014-05-02T19:50:57+00:00

phy_state_machine should check whether auto-negotiatin is completed
before changing phydev->state from PHY_NOLINK to PHY_RUNNING. If
auto-negotiation is not completed phydev->state should be set to
PHY_AN.

net/phy: micrel: fix bugged test on device tree loading for ksz9021

2014-04-23T18:58:58+00:00

In ksz9021_load_values_from_of() val2 to val4 aren't tested against their
initialization value.
This causes the test to always succeed, and this value to be used as if it
was loaded from the devicetree instead of being ignored, in case of a
missing/invalid property in the ethernet OF device node.
As a result, the value "0" is written to the relevant registers.

Change the conditions to test against the right initialization value.

net: ptp: move PTP classifier in its own file

2014-04-01T20:43:18+00:00

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.
