It seem to be non intentionaly changed to tx in
ms commit: adc810900a703ee78fe88fd65e086d359fec04b2
ixgbe: Refactor busy poll socket code to address multiple issues
Lock is taken from ixgbe_low_latency_recv, and there under this
lock we use ixgbe_clean_rx_irq so it looks wrong for me to increment
tx counter.
Yield stats can be shown through ethtool:
ethtool -S enp129s0 | grep yield
