What does this PR do?
Fix putIntoUnackQueueRing function logic for Intercontect interfaces
what
There are several logic issues in the putIntoUnackQueueRing function.
Defect : Misuse of TIMER_SPAN_LOSS (Severity: Medium)
why
For Defect (TIMER_SPAN_LOSS misuse):
Time alignment bias: Expected 5ms boundary alignment, actual 2.5ms alignment
Imprecise retransmission timing: May cause packets to trigger retransmission
too early or too late
Degraded flow control performance: Affects accuracy of timeout-based
mechanisms
Subtle bug: Not immediately obvious during testing but impacts long-term
stability
Overall justification:
These are not just cosmetic issues—they affect correctness (Defect 2) and
code quality (all three)
Low risk fix with high confidence: changes are localized and don't alter
external behavior
Follows best practices: clean code, eliminate redundancy, use correct
constants
How
Perform logical fixes on the premise that existing code functionality
remains intact.
