Hi All,
Attached is version 4 of a patchset to add a new API function to
set the link status on kernel interfaces created with the KNI kernel
module.
v4
====
* Rework rte_kni_update_link to only take linkup/linkdown as parameter,
return previous link state, and remove log messages.
* Update patch to set default carrier state to make default carrier
state configurable by passing the 'carrier=[on|off]' option to
the rte_kni kernel module. This is necessary in order to allow
applications which use KNI as pure virtual interfaces without
corresponding physical ethernet port to use the interfaces without
having to set the carrier state to 'on' via rte_kni_update_link()
or by writing to /sys/devices/virtual/net/<ifaceX>/carrier.
Note that the default is 'off'.
* Add command line flag '-m' to examples/kni to continuously monitor
and update the KNI interface link status according to the link
status of the corresponding physical ethernet port.
> v3
> ====
> * Use separate function to test rte_kni_update_link() in 'test' app.
>
> * Separate changes to 'test' app into separate patch to facilitate
> possible merge with https://patches.dpdk.org/patch/44730/
>
> * Remove changes to set KNI interfaces to 'up' in example/kni
>
> v2
> ====
>
> * Fix bug where "Fixed" and "AutoNeg" were transposed in the link
> status log message.
>
> * Add rte_kni_update_link() to rte_kni_version.map
>
> * Add rte_kni_update_link() tests to kni_autotest
>
> * Update examples/kni to continuously monitor link status and
> update the corresponding kernel interface with
> rte_kni_update_link().
>
> * Minor improvements to examples/kni: Add log message showing how
> to show/zero stats. Improve zeroing statistics.
>
> Note that checkpatches.sh compains about patch 1/5, but this appears
> to be a bug with check-symbol-change or something. If I move the
> fragment of the patch modifying rte_kni_version.map to the bottom of
> the patch file, it doesn't complain any more... I just don't really
> have time to investigate this right now.
thanks
