Can we remove i40e bulk alloc option?

As the receiving functions are different for bulk_alloc or not, we need this flag.

What brings the non bulk alloc function?

Bulk-alloc means it will allocate mbufs in bulk, which was added before we supporting
Vector PMD long long ago, to show the possible better performance.
I think all was disabled by default, and later it is enabled by default for Linux.

Yes, I know that. My question was:
Why not removing the non bulk alloc Rx in i40e?
Who needs to disable I40E_RX_ALLOW_BULK_ALLOC?

I think you understand that the goal is remove some options and code
useless nowadays (maintenance stuff).
