Hope everyone is doing good.
Do you have any idea why the stat values for an F_port might be as follows:
tim_txcrd_z 299520303 Time TX Credit Zero (2.5Us ticks)
tim_txcrd_z_vc 0- 3: 0 0 0 0
tim_txcrd_z_vc 4- 7: 299520303 0 0 0
tim_txcrd_z_vc 8-11: 0 0 0 0
tim_txcrd_z_vc 12-15: 0 0 0 0
As far as I know VC is related to ISL. What are these values stand for ?
And also each line has 4 columns, what does it mean ?

The output of portregshow is the same one, no matter if the port works as an F-port or an E-port.
An F-port, even if it does not use VC, it measures the tim_txcrd_z and the register where it is stored is that one. Thre register used will change depending on the second byte of the Area# in the PID.
