can: slcan: add ethtool support to reset adapter errors
This patch adds a private flag to the slcan driver to switch the
"err-rst-on-open" setting on and off.
"err-rst-on-open" on - Reset error states on opening command
"err-rst-on-open" off - Don't reset error states on opening command
(default)
The setting can only be changed if the interface is down:
ip link set dev can0 down
ethtool --set-priv-flags can0 err-rst-on-open {off|on}
ip link set dev can0 up
