NAME
     mac_capab_lso,  lso_basic_tcp_ipv4  -  LSO  capability  data
     structure

SYNOPSIS
     #include 


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 capabil-
     ity.

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 dev-
         ice  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  sup-
     ported by the driver instance.
