`<net/protocols/netd.h>`¶

netd's service protocol: driver handshake and network interface queries.

#include <net/protocols/netd.h>

Types¶

Type	Definition	Description
`Ipv4Addr`	`uint32_t`	IPv4 address in network byte order.
`NetPort`	`uint16_t`	TCP or UDP port.
`MacAddr`	`uint8_t`	Ethernet MAC address.

Name	Value	Description
`IP4(x)`		Expands an IPv4 address in network byte order into four printf arguments, for "%u.%u.%u.%u".

One-byte opcodes on netd's service port.

Name	Value	Description
`NETD_GET_NETIF`	`1`	Read the interface configuration (NetdNetif).
`NETD_DRVHANDSHAKE_INIT`	`2`	Driver begins: grants its doorbell and sends its MAC.
`NETD_DRVHANDSHAKE_STAGE2`	`3`	Grants the tx ring's memory.
`NETD_DRVHANDSHAKE_STAGE3`	`4`	Grants the rx ring's memory; the reply holds the name.
`NETD_DRVNOTIFY`	`5`	Reserved; unused.
`NETD_DRVWATCH`	`6`	Reserved; unused.
`SOCKET_UDP`	`7`	Reserved; sockets use the SOCK_* commands in net/socket.h.
`SOCKET_UDP_RECV`	`8`	Reserved.
`SOCKET_UDP_SENDTO`	`9`	Reserved.
`SOCKET_TCP`	`10`	Reserved.
`SOCKET_TCP_RECV`	`11`	Reserved.
`SOCKET_TCP_SEND`	`12`	Reserved.
`SOCKET_TCP_ACCEPT`	`13`	Reserved.
`SOCKET_BIND`	`14`	Reserved.
`SOCKET_CONNECT`	`15`	Reserved.
`SOCKET_LISTEN`	`16`	Reserved.
`SOCKET_CLOSE`	`17`	Reserved.
`SOCKET_IP`	`18`	Reserved: raw IP sockets.
`SOCKET_FRAME`	`19`	Reserved: raw Ethernet sockets.
`NETD_OPCODE_COUNT`	`20`	Number of opcodes.

Request carrying a bare NetdOpcode; currently unused.

Field	Type	Description
`op`	`NetdOpcode`	The opcode.

One network interface's configuration, as NETD_GET_NETIF returns it.

Field	Type	Description
`ip`	`Ipv4Addr`	Interface address.
`netmask`	`Ipv4Addr`	Subnet mask.
`gateway`	`Ipv4Addr`	Default gateway.
`dns`	`Ipv4Addr`	DNS server.
`mac`	`MacAddr`	Hardware address.
`name`	`char`	Interface name, NUL-terminated.
