stmmac: export DMA TX/RX rings via debugfs (v3)
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
