Generic segmentation offload (GSO) and generic receive offload (GRO)
—Detects
features supported by the NIC automatically. If the NIC supports fragmentation, the system
sends TCP fragments to the NIC directly. If the network adapter does not support fragmentation,
the system fragments the packets first, and then sends the fragments to the NIC.
RDMA
RDMA is a remote direct memory access technology, aiming to deal with the data processing delay
on the server during network transmission. It transmits data to the storage area of a computer
through network directly and moves data from a system to a remote system storage media rapidly
without impacting the operating system. It reduces the overhead of copying and context switching for
the external storage media, and frees memory bandwidth and CPU cycles, optimizing the application
system performance.
The network adapter supports iWARP and RoCE RDMA protocols.
