This stack of patches introduces a couple of new NDO methods,
ndo_hwtstamp_get and ndo_hwtstamp_set. These new methods can be
implemented by NIC drivers to allow setting and querying HW
timestamp settings. Drivers implementing these methods will
not need to handle SIOCGHWTSTAMP/SIOCSHWTSTAMP IOCTLs.
The new NDO methods will handle copying request parameters
between user address space and kernel space.

Maxim Georgiev (5):
net: Add NDOs for hardware timestamp get/set
net: Add ifreq pointer field to kernel_hwtstamp_config structure
vlan/macvlan: Add ndo_hwtstamp_get/set support to vlan/macvlan code
path
bond: Add ndo_hwtstamp_get/set support to bond driver
netdevsim: Implement ndo_hwtstamp_get/set methods in netdevsim driver
