- essential support for 7260 chipset and DMA fixes - assign mvm->pm_ops at beginning of function iwl_op_mode_mvm_start. iwl_mvm_mac_setup_register() uses mvm->pm_ops, but it is called before this field is set to a valid value. - disable call to function iwl_mvm_prepare_multicast. This function leads to a pagefault, as it aspects a list of multicast addresses, but the list is empty as it is not generated by this port.
