Looking at current net-next to understand an aspect of TLP (tail loss probe) implementation.
https://tools.ietf.org/html/draft-ietf-tcpm-rack-02 is the source of truth now for TLP and 6.2.1. Phase 1: Scheduling a loss probe Step 1: Check conditions for scheduling a PTO. has following as one of the conditions: (d) The most recently transmitted data was not itself a TLP probe (i.e. a sender MUST NOT send consecutive TLP probes) I would appreciate if someone can help me trace how current code is trying to enforce this requirement. How does it check/track that the last (re)transmitted packet was a tlp probe. Thanks in advance, Hiren
