From: zhida zang @ 2015-01-30 4:48 UTC (permalink / raw)
To: dev
changes:
igb: remove old functions that deal with flex filter
igb: add new functions that deal with flex filter(fit for new API)
testpmd: change the entry for flex filter in cmdline
testpmd: change function call to get flex filter in config
doc: change doc that describes how to use flex filter related functions

From: Jingjing Wu @ 2015-02-15 4:07 UTC (permalink / raw)
To: dev
v2 changes:
- split one patch to patch series
- change the command's format in testpmd.
- add doc changes in testpmd_funcs.rst
- correct the errors reported by checkpatch.pl
The patch set uses new filter_ctrl API to replace old flex filter APIs.
It uses new functions and structure to replace old ones in igb driver, new commands to replace old ones in testpmd, and removes the old APIs.
Jingjing Wu (5):
ethdev: define flex filter type and its structure
e1000: new functions replace old ones for flex filter
testpmd: new commands for flex filter
ethdev: remove old APIs and structures of syn filter
doc: commands changed in testpmd_funcs for flex filter

To: dev
This patch defines new functions dealing with flex filter.
It removes old functions of flex filter in igb driver.
Syn filter is dealt with through entrance eth_igb_filter_ctrl.

From: Jingjing Wu @ 2015-02-15 4:07 UTC (permalink / raw)
To: dev
Following commands of flex filter are removed:
- add_flex_filter (port_id) len (len_value) bytes (bytes_string) mask (mask_value)
priority (prio_value) queue (queue_id)
- remove_flex_filter (port_id) index (idx)
- get_flex_filter (port_id) index (idx)
New command is added for flex filter by using filter_ctrl API and new flex filter structure:
- flex_filter (port_id) (add|del) len (len_value) bytes (bytes_value) mask (mask_value)
priority (prio_value) queue (queue_id)

The patch set uses new filter_ctrl API to replace old flex filter APIs.
It uses new functions and structure to replace old ones in igb driver, new commands to replace old ones in testpmd, and removes the old APIs.
v3 changes:
- fix testpmd documentation
v2 changes:
- split one patch to patch series
- change the command's format in testpmd.
- add doc changes in testpmd_funcs.rst
- correct the errors reported by checkpatch.pl
Jingjing Wu (5):
ethdev: define flex filter type and its structure
e1000: new functions replace old ones for flex filter
testpmd: new commands for flex filter
ethdev: remove old APIs and structures of flex filter
doc: commands changed in testpmd_funcs for flex filter

From: Pablo de Lara @ 2015-02-21 1:53 UTC (permalink / raw)
To: dev
From: Jingjing Wu <jingjing.wu@intel.com>
Following commands of flex filter are removed:
- add_flex_filter (port_id) len (len_value) bytes (bytes_string) mask (mask_value)
priority (prio_value) queue (queue_id)
- remove_flex_filter (port_id) index (idx)
- get_flex_filter (port_id) index (idx)
New command is added for flex filter by using filter_ctrl API and new flex filter structure:
- flex_filter (port_id) (add|del) len (len_value) bytes (bytes_value) mask (mask_value)
priority (prio_value) queue (queue_id)

Structure rte_flex_filter is removed.
Following APIs are removed:
- rte_eth_dev_add_flex_filter
- rte_eth_dev_remove_flex_filter
- rte_eth_dev_get_flex_filter
