I'm at a loss... (3 Replies)

In Solaris 10 it was easy, a simple grep through modinfo output and you'd have the version of any loaded module, including your NIC drivers. In my career I've seen many people relying on this information in their scripts. Now I'm on Solaris 11, and where have the version numbers gone? The... (0 Replies)

net_isvalidchecksum
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.
