Subject: [RFC PATCH v4 0/5] New NDO methods ndo_hwtstamp_get/set

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):
  Add NDOs for hardware timestamp get/set
  Add ifreq pointer field to kernel_hwtstamp_config structure
  Add ndo_hwtstamp_get/set support to vlan/maxvlan code path
  Add ndo_hwtstamp_get/set support to bond driver
  Implement ndo_hwtstamp_get/set methods in netdevsim driver
