On my board (SKX):
 for micro-benchmark (doing nothing but setting tx_offload for 1M mbufs in a loop) 
the difference is more than 150% -  from ~55 cycles to ~20 cycles per iteration.
For ipsec-secgw - ~3% improvement for tunneled outbound packets.

No big difference here, just looks nicer to me.

NP, can do this way.

I thought about such approach, but as you said above it would change
from unnamed struct to named one.
Which, as I understand, means API breakage.
So don't think the hassle will be worth the benefit.
Also the code wouldn't be totally identical - that approach will generate few
extra 'AND' instructions.
