[PATCH] ixgbe/igb: integrate syn filter to new API

[PATCH] ixgbe/igb: integrate syn filter to new API

[zhida zang]

This patch integrates syn filter to new API in ixgbe/igb driver.

changes:
ixgbe: remove old functions that deal with syn filter
ixgbe: add new functions that deal with syn filter (fit for filter_ctrl API)
e1000: remove old functions that deal with syn filter
e1000: add new functions that deal with syn filter (fit for filter_ctrl API)
testpmd: change the entry for syn filter in cmdline
testpmd: change function call to get syn filter in config

[PATCH v2 0/6] Integrate syn filter in igb/ixgbe driver to new API

[Jingjing Wu]

v2 changes:
 - split one patch to patch series
 - change the command's format in testpmd.
 - return -ENOENT when deleting a disabled syn filter.
 - 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 syn filter APIs.
It uses new functions and structure to replace old ones in igb/ixgbe driver,
new commands to replace old ones in testpmd, and removes the old APIs.

Jingjing Wu (6):
  ethdev: define syn filter type and its structure
  ixgbe: new functions replace old ones for syn filter
  e1000: new functions replace old ones for syn filter
  testpmd: new commands for syn filter
  ethdev: remove old APIs and structures of syn filter
  doc: commands changed in testpmd_funcs for syn filter

[PATCH v2 4/6] testpmd: new commands for syn filter

[Jingjing Wu]

Following commands of syn filter are removed:
  - add_syn_filter (port_id) priority (high|low) queue (queue_id)
  - remove_syn_filter (port_id)
  - get_syn_filter (port_id)
New command is added for syn filter by using filter_ctrl API and new
syn filter structure:
  - syn_filter (port_id) (add|del) priority (high|low) queue (queue_id)

Re: [PATCH v2 0/6] Integrate syn filter in igb/ixgbe driver to new API

[Wu, Jingjing]

Because the first version of the patch is sent by Zhida, and he is on a long vacation now, I have no right to change the old patch's status in patch work. 
Sorry for the inconvenience.

Thanks
Jingjing

Applied, thanks.
I removed the old API functions from the version map.
