Comment (by dgoulet):
So I want to fully understand here. The goal is:
1) Record when a cell is created with the amount of bytes
--> Keep in state the cell ID and size for a specific connection X.
2) Record the amount of bytes once it's packed (??)
--> Update the state with the packed size for the cell ID and connection
X.
--> Record the position of the packed cell in the output buf just after we
wrote in it.
3) Record when that specific cell is written to the kernel
--> For connection X, record when the cell ID has been written to the
kernel.
Is that correct?
