net_phylookup(9F) Kernel Functions for Drivers net_phylookup(9F) NAME
net_phylookup - determine if a network interface name exists for a network protocol SYNOPSIS
#include <sys/neti.h> phy_if_t net_phylookup(const net_data_t net, const char *name); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
net value returned from a successful call to net_protocol_lookup(9F). name name of the network interface to find. DESCRIPTION
The net_phylookup() function attempts to resolve the interface name passed in with the network protocol. When called successfully, the value returned represents a network interface that exists, at the time of the call, within the scope of the network interface. This value is only guaranteed to be unique for a name within the scope of the network protocol. RETURN VALUES
The net_phylookup() function returns -1 if it is not supported by the network protocol, and 0 if the named network interface does not exist (or is otherwise unknown). Otherwise, it returns a value greater than 0 representing a network interface that currently exists within the scope of this network protocol. CONTEXT
The net_phylookup() function may be called from user, kernel, or interrupt context. ATTRIBUTES

net_ispartialchecksum(9F) Kernel Functions for Drivers net_ispartialchecksum(9F) 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
