User sets CFR data transport mode using vendor command
QCA_NL80211_VENDOR_SUBCMD_PEER_CFR_CAPTURE_CFG. By default
CFR data transport mode is relayfs, user uses vendor command
attr QCA_WLAN_VENDOR_ATTR_PEER_CFR_DATA_TRANSPORT_MODE to set
transport mode QCA_WLAN_VENDOR_CFR_DATA_RELAY_FS or
QCA_WLAN_VENDOR_CFR_DATA_NETLINK_EVENTS.
If user sets QCA_WLAN_VENDOR_ATTR_PEER_CFR_DATA_RECEIVER_PID
attr in QCA_NL80211_VENDOR_SUBCMD_PEER_CFR_CAPTURE_CFG vendor
command then hosts uses RECEIVER_PID to send unicast NL events
for CFR data.
