NetOffloadIsLsoIPv4Enabled function (netadapteroffload.h)
The NetOffloadIsLsoIPv4Enabled function determines whether a net adapter has large send offload (LSO) enabled for IPv4 packets.
Syntax
BOOLEAN NetOffloadIsLsoIPv4Enabled(
[_In_] NETOFFLOAD Offload
);
Parameters
[_In_] Offload
A NETOFFLOAD object that represents the net adapter's generic send offload (GSO) capabilities.
Return value
Returns TRUE if LSO is enabled for IPv4 packets, or FALSE if it is not.
