Abstract:
1. A computer implemented method for virtual segmentation off-load in a logically partitioned data processing system, the computer implemented method comprising: formatting a data message for segmentation off-load to form a virtual segmentation off-load package that contains all data from the data message without any segmentation of the data message even though a size of the data message is larger than a maximum transmission unit size; copying the virtual segmentation off-load package in its entirety as a single unit of data without performing a segmentation operation on the data message associated with the virtual segmentation off-load package from a first logical partition to a virtual network adapter associated with a second logical partition even though the virtual segmentation off-load package is larger than the maximum transmission unit size; and responsive to receiving the virtual segmentation off-load package from a virtual network adapter associated with the first logical partition, passing the virtual segmentation off-load package to a transmission control protocol stack on the second logical partition by the virtual network adapter associated with the second logical partition, wherein a checksum operation is not performed on the virtual segmentation off-load package received from the first logical partition.
