mac_capab_lso(9S) Data Structures for Drivers mac_capab_lso(9S)NAME
mac_capab_lso, lso_basic_tcp_ipv4 - LSO capability data structure
SYNOPSIS
#include <sys/mac_provider.h>
INTERFACE LEVEL
Solaris architecture specific (Solaris DDI)
DESCRIPTION
The mac_capab_lso and lso_basic_tcp_ipv4 structures are used by a
device driver to describe its LSO capability. The structure is used as
the argument to the mc_getcapab(9E) driver entry point when querying
the MAC_CAPAB_LSO capability.
STRUCTURE MEMBERS
The mac_capab_lso data structure has the following members:
t_uscalar_t lso_flags;
lso_basic_tcp_ipv4_t lso_basic_tcp_ipv4;
The fields must be set as follows:
lso_flags
Flag indicating the LSO capability supported by the device driver
instance. The following flags are currently supported:
LSO_TX_BASIC_TCP_IPV4 LSO for TCP on IPv4
lso_basic_tcp_ipv4
Parameters for TCP LSO over IPv4
The lso_basic_tcp_ipv4 data structure is used by the device driver to
advertise specific parameters when the LSO_TX_BASIC_TCP_IPV4 lso_flag
is set. This data structure has the following elements:
t_uscalar_t lso_max;
The lso_max field contains the maximum payload size supported by the
driver instance.
