net_inject_t(9S)					    Data Structures for Drivers 					  net_inject_t(9S)

NAME
net_inject_t - structure for describing how to transmit a packet SYNOPSIS
#include <sys/neti.h> INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). DESCRIPTION
The net_inject_t data structure passes information in to net_inject about how to transmit a packet. Transmit includes sending the packet up into the system as well as out of it. STRUCTURE MEMBERS
mblk_t *ni_packet; /* start of the packet */ struct sockaddr_storage ni_addr; /* address of next hop */ phy_if_t ni_physical; /* network interface to use */ ni_packet Pointer to the first the mblk_t data structure that makes up this packet. ni_addr This field is only required to be initialized if NI_DIRECT_OUT is being used to transmit the packet. The sockaddr_storage field must be set to indicate whether the destination address contained in the structure is IPv4 (cast ni_addr to struct sockaddr_in) or IPv6 (cast ni_addr to struct sockaddr_in6). ni_physical The physical interface where the packet will be injected.

hook_pkt_event(9S)					    Data Structures for Drivers 					hook_pkt_event(9S)

NAME
hook_pkt_event - packet event structure passed through to hooks SYNOPSIS
#include <sys/neti.h> #include <sys/hook.h> #include <sys/hook_event.h> INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). DESCRIPTION
The hook_pkt_event structure contains fields that relate to a packet in a network protocol handler. This structure is passed through to a callback for NH_PRE_ROUTING, NH_POST_ROUTING, NH_FORWARDING, NH_LOOPBACK_IN and NH_LOOPBACK_OUT events. A callback may only modify the hpe_hdr, hpe_mp and hpe_mb fields. The following table documents which fields can be safely used as a result of each event. Event hpe_ifp hpe_ofp hpe_hdr hpe_mp hpe_mb ----- ------- ------- ------- ------ ------ NH_PRE_ROUTING yes yes yes yes NH_POST_ROUTING yes yes yes yes NH_FORWARDING yes yes yes yes yes NH_LOOPBACK_IN yes yes yes yes NH_LOOPBACK_OUT yes yes yes yes STRUCTURE MEMBERS
net_data_t hne_family; phy_if_t hpe_ifp; phy_if_t hpe_ofp; void *hpe_hdr; mblk_t *hpe_mp; mblk_t *hpe_mb; uint32_t hpe_flags; The following fields are set for each event: hne_family The protocol family for this packet. This value matches the corresponding value returned from a call to net_proto- col_lookup(9F). hpe_ifp The inbound interface for a packet. hpe_ofp The outbound interface for a packet. hpe_hdr Pointer to the start of the network protocol header within an mblk_t structure. hpe_mp Pointer to the mblk_t pointer that points to the first mblk_t structure in this packet. hpe_mb Pointer to the mblk_t structure that contains hpe_hdr. hpe_flags This field is used to carry additional properties of packets. The current collection of defined bits available is: HPE_BROADCAST This bit is set if the packet was recognized as a broadcast packet from the link layer. The bit cannot be set if HPE_MULTICAST is set, currently only possible with physical in packet events. HPE_MULTICAST This set if the packet was recognized as a multicast packet from the link layer. This bit cannot be set if HPE_BROADCAST is set, currently only possible with physical in packet events. ATTRIBUTES
