When an i40e PF port is stopped, all mirror rules should be reserved.
But when an i40e PF port is closed, all mirror rules should be removed.
When a mirror rule is removed, its associated hardware and software
resource should also be removed.
Fixes: a4def5edf0fc ("i40e: enable port mirroring")

In order to support more than 256 virtual ports, the field "port"
in rte_mbuf has been increased to 16 bits. The initialization/reset

port_id is currently defined as uint8_t, which is limited to the range
0 to 255. A larger range is required for vdev scalability.
It is necessary for a redefinition of port_id to extend it from
1 bytes to 2 bytes. All ethdev APIs and usages related to port_id will
be changed at the same time.

Currently, only QEMU sends requests, the backend sends

requests to QEMU, like IOTLB miss events when IOMMU is
supported.
This patch introduces a new channel for such requests.
QEMU sends a file descriptor of a new socket using
VHOST_USER_SET_SLA
