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_isvalidchecksum(9F) Kernel Functions for Drivers net_isvalidchecksum(9F) NAME
net_isvalidchecksum - verify layer 3 and layer 4 checksums SYNOPSIS
#include <sys/neti.h> int net_isvalidchecksum(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_isvalidchecksum() function verifies the layer 3 checksum (and, in some case, the layer 4 checksum) in the packet. If possible, fields that are used by hardware checksum'ing are examined rather than manually verifying that the checksums are present for packets received from a network interface. For both IPv4 and IPv6, TCP, UDP and ICMP (including ICMPV6 for IPv6) layer 4 checksums are currently validated. RETURN VALUES
The net_isvalidchecksum() function returns: -1 The network protocol does not support this function. 0 The packet does not contain partial checksums. 1 The packet does contain partial checksums. CONTEXT
The net_isvalidchecksum() function may be called from user, kernel, or interrupt context. ATTRIBUTES
