It is related. Because as part of the offloads API the Tx offloads configuration is set on the rte_eth_dev_configure. To configure a device it must be stopped in advance.
Also, per my understanding, the only API which allows offloads configuration on the flight are the Rx VLAN offloads.
As you can see, this API is respected and no need to check the port status in it

Only for the Rx vlan. The Tx vlan insert is not configured on the flight.
That's why the original code doesn't have this restriction.

The original code doesn't have such restriction because testpmd wasn't configuring Tx offloads at all. It used it's own Tx offloads enum (which I removed on later patches) to indicate which offloads is set. From the device perspective all the Tx offloads should be set.
It did had a way to configure offloads with txqflags parameter, but this required queues reconfigurations.
