Data:

qwf_net_IfName_t name: Network interface name
qwf_net_IfType_e ifType: Network interface type
bool connected: Whether the interface is connected
bool physicalUp: Whether the physical interface is up
bool hasIpAddr: Whether the interface has an IP address
bool ip4: Whether the interface has an IPv4 address
bool ip6: Whether the interface has an IPv6 address
uint8_t fib: FIB (Forwarding Information Base) for the network interface
uint16_t mtu: MTU (Maximum Transmission Unit) for the network interface
qwf_net_IpAddrStr_t ip4Address: IPv4 address (if available)
qwf_net_IpAddrStr_t ip4Netmask: IPv4 netmask (if IPv4 is available)
qwf_net_IpAddrStr_t ip4Gateway: IPv4 gateway
qwf_net_IpAddrStr_t ip6Address: IPv6 address (if available)
uint8_t ip6NetPrefixLen: IPv6 network prefix length (if IPv6 is available), as the number of bits used for the mask. The maximum prefix length is 128.
qwf_net_IpAddrStr_t ip6Gateway: IPv6 gateway
qwf_net_IpAddrStr_t broadcast: Broadcast IP address
char mac[QWF_NET_MAX_MAC_ADDR_LEN+1]: MAC address for the interface
qwf_net_IpAddrStr_t ip4NameServers[QWF_NET_NUM_DNS_ADDRS]: IPv4 primary and secondary name servers for the interface, as an array of IP addresses
qwf_net_IpAddrStr_t ip6NameServers[QWF_NET_NUM_DNS_ADDRS]: IPv6 primary and secondary name servers for the interface, as an array of IP addresses
char searchDomain[QWF_NET_MAX_DNS_NAME_LEN+1]: Search domain name(s) for the interface. This field is informational only. Multiple search domain names are delimited by commas in the string.
qwf_net_IpConfigMethod_e ip4ConfigMethod: Whether the IPv4 interface settings are configured manually, DHCP settings are applied, or the interface won't be considered for IPv4 selection.
qwf_net_IpConfigMethod_e ip6ConfigMethod: Whether the IPv6 interface settings are configured manually, DHCPv6 settings are applied, or the interface won't be considered for IPv6 selection.
bool unmanaged: Whether the interface is being managed internally
