Subject: [PATCH v2 3/6] net: MOXA ART: add ethtool support
Add and assign ethtool_ops callback functions.
Signed-off-by: Jonas Jensen <jonas.jensen@...il.com>
---
Notes:
Thanks for reviewing!
Changes since v1:
1. declare MOXART_NUM_STATS with ARRAY_SIZE macro
2. don't initialise info->n_stats in moxart_get_drvinfo()
3. remove "if (!priv->phy_dev) return -ENODEV;"
moxart_get_settings(), moxart_set_settings(), moxart_nway_reset()
Applies to next-20131125
