[dpdk-dev] [PATCH 14/20] net/i40e/base: add AQ command for rearrange NVM structure

[Qi Zhang]

During switching between old NVM structure approach (called
structured NVM) to new one (called flat NVM) or backward flash
needs to be rearranged to required NVM structure.
This is a part of transition from one NVM structure to another.
The function is introduced to command firmware to start
rearrangement process.
