Subject: IB/IPoIB: Add support for hwtstamp get/set ndos
X-Git-Tag: v6.19-rc1~170^2~264^2~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=250da3c8fe811b14fd5e610760ed7469166fd0f7;p=thirdparty%2Fkernel%2Flinux.git

IB/IPoIB: Add support for hwtstamp get/set ndos

Add support for the ndo_hwtstamp_get and ndo_hwtstamp_set operations in
IPoIB. This allows lower devices to handle hardware timestamp
configuration through the new ndos instead of the legacy ioctls.
