• Bug fix in bw_meter_process(): the periodically processed bins of bw_meter entries were processed up to one second ahead. After an unappropriate rescheduling of some of the bw_meter entries, the upcalls weren't delivered.

• pim_register_prepare() uses the appropriate sw_csum flag to call ip_fragment() so the IP checksum is computed properly.

• Modify pim_register_prepare() to take care of IP packets that don't need fragmentation.

• Add-back in_delayed_cksum() to encap_send(), because it seems it should be there.
