Detailed Description
TCLink with default settings optimized for UserSwitch (txo=rxo=0/False).
Unfortunately with recent Linux kernels, enabling TX and RX checksum offload on veth pairs doesn't work well with
- Parameters
-
UserSwitch either it gets terrible performance or TCP packets with bad checksums are generated, forwarded, and dropped due to having bad checksums! OVS and LinuxBridge seem to cope with this somehow, but it is likely to be an issue with many software Ethernet bridges.
The documentation for this class was generated from the following file:
- mininet/link.py
