摘要：
A method for virtual segmentation off-load in a logically partitioned data processing system is provided. A data transmission protocol stack formats a data message for segmentation off-load to form a virtual segmentation off-load package. The size of the data message is larger than a size of a maximum transmission unit. A partition manager firmware copies the virtual segmentation off-load package from a first logical partition to a virtual Ethernet adapter associated with a second logical partition. The virtual segmentation off-load package is copied without performing a segmentation operation on the data message associated with the virtual segmentation off-load package.
