Pass the ESR as the trapno value; this might help in determining the detailed cause of a signal. ok bluhm@, guenther@, deraadt@ |

Implement the TCP/IP layer for hardware TCP segmentation offload. If the driver of a network interface claims to support TSO, do not chop the packet in software, but pass it down to the interface layer. Precalculate parts of the pseudo header checksum, but without the packet length. The length of all generated smaller packets is not known yet. Driver and hardware will use the mbuf packet header field ph_mss to calculate it and update checksum. Introduce separate flags IFCAP_TSOv4 and IFCAP_TSOv6 as hardware might support ony one protocol family. The old flag IFXF_TSO is only relevant for large receive offload. It is missnamed, but keep that for now. Note that drivers do not set TSO capabilites yet. Also the ifconfig flags and pseudo interfaces capabilities will be done separately. So this commit should not change behavior. heavily based on the work from jan@; OK sashan@ |
