NAME
net_ispartialchecksum - indicate if a packet is being scheduled for hardware checksum calculation SYNOPSIS
#include <sys/neti.h> int net_ispartialchecksum(const net_data_t net, mblk_t *mb); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
net value returned from a successful call to net_protocol_lookup(9F). mb the mblk structure holding a packet that is the subject of this query. DESCRIPTION
The net_ispartialchecksum() function looks at the fields within the mblk structure to determine if the packet contained inside contains headers with only partial checksum values. Partial checksum values are stored inside headers when the calculation of the complete checksum is being handled by the hardware. RETURN VALUES
The net_ispartialchecksum() function returns: -1 The network protocol does not support this function. 0 The packet does not contain partial checksums. If a packet is marked for hardware checksum'ing, the following values are returned: NET_HCK_L3_FULL Complete layer 3 checksum calculated NET_HCK_L3_PART Partial layer 3 checksum calculated NET_HCK_L4_FULL Complete layer 4 checksum calculated NET_HCK_L4_PART Partial layer 4 checksum calculated CONTEXT
The net_ispartialchecksum() function may be called from user, kernel, or interrupt context. ATTRIBUTES

NAME
net_routeto - indicate which network interface packets are sent SYNOPSIS
#include <sys/neti.h> phy_if_t net_routeto(const net_data_t *net, struct sockaddr *address, struct sockaddr *nexthop); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
net value returned from a successful call to net_protocol_lookup(9F). address network address to find a path out of the machine for. nexthop pointer to the sockaddr structure in which to store the address of the next hop. If this information is not required, the value NULL may be passed instead. DESCRIPTION
The net_routeto() function indicates which network interface packets destined for a particular address would be sent out of, according to the systems network routing tables. If next is supplied as a non-NULL pointer, the IP address of the nexthop router to be used is returned in it. RETURN VALUES
The net_routeto() function returns: -1 The network protocol does not support this function. 0 This function cannot find a route for the address given. >0 Indicates which network interface can be used to reach the given address. CONTEXT
The net_routeto() function may be called from user, kernel, or interrupt context. ATTRIBUTES
