====================
dpaa2-eth: add debugfs statistics

This patch set exports detailed driver counters through debugfs.
Counters which are already available through ethtool are now
presented in a structured manner (per-core, per-FQ and
per-channel) in debugfs.

The first patch is changing the dpaa2_eth_queue_count into a macro
(in order to avoid a warning) while the second one is adding the
debugfs support.

Changes in v2:
  - remove the _exit annotation of dpaa2_eth_dbg_exit
