This patch adds the following debugFs entry to dump the RX/TX DMA rings: /sys/kernel/debug/stmmaceth/descriptors_status This is an example: ======================= RX descriptor ring ======================= [0] DES0=0x85ee0320 DES1=0x1fff1fff BUF1=0x5fae2022 BUF2=0x0 [1] DES0=0x85ee0320 DES1=0x1fff1fff BUF1=0x5fae0022 BUF2=0x0 [2] DES0=0x81460320 DES1=0x1fff1fff BUF1=0x5f9dd022 BUF2=0x0 Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S.

Selecting this option, rx has priority over Tx (only for Giga

By default, the DMA arbitration scheme is based on Round-robin
