Field Documentation

◆ list

struct list_head ipv4_miniroute::list

List of miniroutes.

Definition at line 60 of file ip.h.

◆ netdev

struct net_device* ipv4_miniroute::netdev

Network device.

◆ address

struct in_addr ipv4_miniroute::address

IPv4 address.

Definition at line 66 of file ip.h.

Referenced by add_ipv4_miniroute(), del_ipv4_miniroute(), ipv4_has_addr(), ipv4_route(), ipv4_tx(), and route_ipv4_print().

◆ netmask

struct in_addr ipv4_miniroute::netmask

Subnet mask.

An address with all of these bits in common with our IPv4 address is in the local subnet.

Definition at line 72 of file ip.h.

Referenced by add_ipv4_miniroute(), del_ipv4_miniroute(), ipv4_route(), and route_ipv4_print().

◆ hostmask

struct in_addr ipv4_miniroute::hostmask

Host mask.

An address in the local subnet with all of these bits set to zero represents the network address, and an address in the local subnet with all of these bits set to one represents the directed broadcast address. All other addresses in the local subnet are valid host addresses.

For most subnets, this is the inverse of the subnet mask. In a small subnet (/31 or /32) there is no network address or directed broadcast address, and all addresses in the subnet are valid host addresses.

Referenced by add_ipv4_miniroute(), and ipv4_tx().

◆ gateway

struct in_addr ipv4_miniroute::gateway

Gateway address, or zero for no gateway.
