I would need to investigate what is involved in moving the rte_pmd_ixgbe_* functions to a separate file.
They may be using some of the static functions and data in the ixgbe_ethdev.c file which could be a problem.
The rte_pmd_ixgbe_* functions are considered an "interim solution" until a "generic solution" is agreed.
It might be best to postpone this work until the "generic solution" is agreed.

Bernard.
