Subject: Re: [PATCH 2/3] net: mana: Implement set_link_ksettings in ethtool
 for speed

So how do i remove the speed limitation i previously installed? -1 is
SPEED_UNKNOWN which is what you default to.

Using TC would be more natural in this case. The user action is to
remove the TC filter and that should set it back to unlimited.
