This change makes it so that we can use the atr_sample_rate to determine if we are capable of supporting ATR. The advantage to this approach is that it allows us to now determine the setting of the IXGBE_FLAG_FDIR_HASH_CAPABLE based on the queueing scheme, instead of the queueing scheme being based on the flag. Using this approach there are essentially 5 conditions that must be checked prior to trying to enable ATR: 1. Is SR-IOV disabled? 2. Are the number of TCs <= 1? 3. Is RSS queueing limit greater than 1? 4. Is atr_sample_rate set? 5. Is Flow Director perfect filtering disabled? If any of these conditions are enabled they should disable ATR filtering. Note that in the case of conditions 1 through 4 being met we will set things up for ATR queueing, however if test 5 fails we will still leave the queues allocated for use by perfect filters. The reason for this is to allow for us to switch back and forth between ntuple and ATR without needing to reallocate the descriptor rings.
