In my mind that > is just LRO. I say subset since odds are you don't support all of the > same protocols and tunnels that GRO in software does. Of course, hardware has some limitations, such as the number of TCP connections it can aggregate, etc. But again, it is different from LRO.
Webgeneric receive offload (GRO) which in turn allows us to send a single thread of encapsulated frames at rates exceeding 10Gbps with test tools such as netperf. This paper will go over the kernel work that has been done to enable these features, demonstrate the benefits of the features, explain what settings need to be configured in order to get the WebFeb 28, 2024 · Generic Receive Offload (GRO) is a widely used SW-based offloading technique to reduce per-packet processing overheads. By reassembling small packets into larger ones, GRO enables applications to process fewer large packets directly, thus reducing the number of packets to be processed. In computer networking, large receive …
WebThe field NAPI_GRO_CB(skb)->proto is used by GRO to hold the layer 4 protocol type that comes after the IPv6 layer. I noticed that it is set in ipv6_gro_receive, but isn't used anywhere. By using this field, and also storing the size of the network header, we can avoid parsing extension headers a second time in ipv6_gro_complete. WebGeneric Receive Offload¶ Generic receive offload is the complement to GSO. Ideally any frame assembled by GRO should be segmented to create an identical sequence of frames using GSO, and any sequence of frames segmented by GSO should be able to be reassembled back to the original by GRO. The only exception to this is IPv4 ID in the …
WebThis requests that the NIC enables Hardware GRO (generic receive offload). Hardware GRO is basically the exact reverse of TSO, and is generally stricter than Hardware LRO. A packet stream merged by Hardware GRO must be re-segmentable by GSO or TSO back to the exact original packet stream. Hardware GRO is dependent on RXCSUM since every …
