Currently the ice_q_vector structure and ice_ring_container structure are taking up more space than necessary due to cache alignment holes and unnecessary variables respectively. This is not helping the driver's performance. The following fixes were done to improve cache alignment, reduce wasted space, and increase performance. 1. Remove the ice_latency_range enum as it is unused. 2. Remove the latency_range variable in the ice_ring_container structure. 3. Change the size of the itr_idx in the ice_ring_container structure from an int to an u16. This reduced the size of ice_ring_container structure to 32 Bytes so it has no holes or padding. 4. Re-arrange the ice_q_vector structure using pahole to align members as best as possible in regards to 64 Byte cache line size.
