Commit af9bf70 ("net: stmmac: add ethtool per-queue irq statistic support") introduced ethtool per-queue statistics support to display number of interrupts generated by DMA tx and DMA rx for DWMAC4 core. This patch extend the support to XGMAC core. Signed-off-by: Teoh Ji Sheng <ji.sheng.teoh@intel.com>
