Subject: ath79: ag71xx: update ethtool support
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=206af613b2441f15bc469dea223ff6fa4e5aa55e;p=openwrt%2Fstaging%2Fstintel.git

ath79: ag71xx: update ethtool support

ethtool doesn't work currently as phy_ethtool_ioctl expects user space
pointer, but it's being passed kernel one. Fixing it doesn't make sense
as {s,g}et_settings were deprecated anyway.  So let's rather remove
phy_ethtool_ioctl and use new {s,g}et_link_ksettings instead. While at
it, update nway_reset as well.
