[PATCH v4 00/11] Trace subsystem fixes and more

[David Marchand]

Hello,

This series addresses a number of issues and limitations I have
identified over time in the trace subsystem.

The main issue was with dynamically enabling trace points which was not
working if no trace point had been enabled at rte_eal_init() time.

This is 22.11 material.

We may start thinking about marking this API stable, but this is another
topic.
