    "content": "As we may know, we have eal event for rte device hotplug and ethdev event\nfor ethdev hotplug. Some ethdev need to use eal event to detect hotplug\nbehaviors, the privors way is register eal event callback in app, but seems\nthat it will have some race between these 2 event processes. In oder to fix\nthe it, it might be better to find a way to combind these 2 events detect.\n\nThis patch set introduce a way to combind these 2 event, by register the\nethdev eal event callback in pmd driver and trigger the ethdev hotplug event\nin the callback. That will let the ethdev device can easy process hotplug\nby a common way.\n\nHere let i40e/ixgbe pmd driver for example, other driver which support\nhotplug feature could be use this way to detect and process hotplug.\n\npatch history:\nv3->v2:\nremove the callback from driver to ethdev for common.\n\nv2->v1:\nadd ixgbe hotplug detect case.\nrefine some doc.\n\n\nJeff Guo (4):\n  ethdev: Add eal device event callback\n  net/ixgbe: enable hotplug detect in ixgbe\n  net/i40e: enable hotplug detect in i40e\n  testpmd: remove the dev event callback register\n\n app/test-pmd/testpmd.c                 | 76 ----------------------------------\n doc/guides/rel_notes/release_18_08.rst |  8 ++++\n drivers/net/i40e/i40e_ethdev.c         |  7 +++-\n drivers/net/ixgbe/ixgbe_ethdev.c       |  7 +++-\n lib/librte_ethdev/rte_ethdev.c         | 37 +++++++++++++++++\n lib/librte_ethdev/rte_ethdev_driver.h  | 20 +++++++++\n 6 files changed, 77 insertions(+), 78 deletions(-)"
