ixgbe: make q_vectors dynamic to reduce netdev size
Currently the q_vectors are being allocated statically inside of the
adapter struct. This increases the overall size of the adapter struct when
we can easily allocate the vectors dynamically. This patch changes that
behavior so that the q_vectors are allocated dynamically and the napi
structures are automatically allocated inside of the q_vectors as needed.
