There is a way to update via CLI
For example when doing "tso set <mss> <port>" the DEV_TX_OFFLOAD_TSO will be set
When doing tx_vlan add <port> <vlan> the DEV_TX_OFFLOAD_VLAN_INSERT will be set
Same for every Tx offloads besides DEV_TX_OFFLOAD_MULTI_SEGS  and DEV_TX_OFFLOAD_MBUF_FAST_FREE which I added on separate patches. 

But to make it precise you didn’t had before (with the txq_flags) a way to disable TSO from the command line (the is no TXQ flag for that) nor the tunnel TSO.

We can do it. yes.

Will be added.
