Subject: [dpdk-dev] [PATCH v2 2/2] i40evf: support interrupt based pf reset
request

Interrupt based request of PF reset from PF is supported by enabling the
adminq event process in VF driver.
Users can register a callback for this interrupt event to get informed, when a
PF reset request detected like:
  rte_eth_dev_callback_register(portid,
		RTE_ETH_EVENT_INTR_RESET,
		reset_event_callback,
		arg);

Two questions,
1.If the VF RX/TX using msix 1 and Admin Queue using msix 0, 
how the two interrupts can both be read in user spaces, in VM VFIO not supported,

2.But if we want to  run l3fwd-power in VF, we can only assign the rx/tx intr to msix0,
but both thread will using epoll to wait the msix0 event, 
and intr thread may miss the vf reset event if l3fwd-power thread clean the msix0 related fd firstly
 if there are no more packets and msg response come in, the intr thread will not be wake up again
