1.2 English

TCP urgent data processing is a rarely-used feature that is inconsistently implemented on various operating systems. In Onload 201811 a new EF_TCP_URG_MODE environment variable has been added, that can be used to ignore this feature.

Important: If urgent data is received when Onload is configured to ignore urgent data processing, then applications that are written to the Linux convention will experience corrupt data.
