Is this correct? an offload not include in FM10K_SIMPLE_TX_OFFLOADS will also fail this branch and pass check, right?
The logic can be implemented like below:
#define FM10K_VEC_TX_OFFLOAD_SUPPORT xxx | xxx ...
If (txq->offloads & FM10K_VEC_TX_OFFLOAD_SUPPORT != txq->offload)
return -1

As there is a comment above show " Vector TX can't offload any features yet"
I'd like to use if (txq->offloads != 0) in my next version of patch.
