H A Dsnmp_counter.rst568 The TCP protocol has two retransmission mechanisms: SACK and fast
569 recovery. They are exclusive with each other. When SACK is enabled,
570 the kernel TCP stack would use SACK, or kernel would use fast
571 recovery. The SACK is a TCP option, which is defined in `RFC2018`_,
