net: hns3: add support for setting VF trust
This patch adds supports for setting VF trust by host. If specified
VF is trusted, then it can enable promisc(include allmulti mode).
If a trusted VF enabled promisc, and being untrusted, host will
disable promisc mode for this VF.
For VF will update its promisc mode from set_rx_mode now, so it's
unnecessary to set broadcst promisc mode when initialization or
reset.
