Arthur Kiyanovski 0574bb806d net: ena: limit refill Rx threshold to 256 to avoid latency issues ... Currently Rx refill is done when the number of required descriptors is above 1/8 queue size. With a default of 1024 entries per queue the threshold is 128 descriptors. There is intention to increase the queue size to 8196 entries. In this case threshold of 1024 descriptors is too large and can hurt latency. Add another limitation to Rx threshold to be at most 256 descriptors.
