  • WifiMode

    WifiMode now has a WifiPhyStandard attribute which identifies the standard the WifiMode belongs to. To properly set this attribute when creating a new WifiMode, it is now required to explicitly pass a WifiPhyStandard parameter to all WifiModeFactory::CreateXXXX() methods. The WifiPhyStandard value of an existing WifiMode can be retrieved using the new method WifiMode::GetStandard().

  • NetDevice +

    In order to have multiple link change callback in NetDevice (i.e. to flush ARP and IPv6 neighbor discovery caches), the following member method has been renamed:

    +
    +- virtual void SetLinkChangeCallback (Callback<void> callback);
++ virtual void AddLinkChangeCallback (Callback<void> callback);
    +Now each NetDevice subclasses have a TracedCallback<> object (list of callbacks) instead of Callback<void> ones. +
