net_getifname(9F) Kernel Functions for Drivers net_getifname(9F) NAME
net_getifname - determine the name given to a network interface SYNOPSIS
#include <sys/neti.h> int net_getifname(const net_data_t net, const phy_if_t ifp, char *buffer, size_t buflen); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
net value returned from a successful call to net_protocol_lookup(9F). ifp value returned from a successful call to net_phylookup(9F) or net_phygetnext(9F). buffer pointer to the buffer in which to write the interface name. buflen size of the buffer in which to store the interface name. DESCRIPTION
The net_getifname() function copies the name of the network interface into the buffer provided. The name will always be null-terminated. If the buffer is too small to fit both the interface name and the null-terminated name, the name in the buffer is truncated to fit. See net_phygetnext(9F) for an example on how to use this function. RETURN VALUES
The net_getifname() function returns: -1 The network protocol does not support this function. 0 Successful completion. 1 Unsuccessful. CONTEXT
The net_getifname() 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
