I wonder if this is a known problem (or me missing something obvious) - outgoing TCP packets to be sent via the built-in ethernet device (GMace) appear to have only MBUF_CSUM_REQ_SUM16 hardware checksum request flag set as seen by an output KPI interface filter, which needs to modify the packet and therefore calls mbuf_outbound_finalize to do the delayed checksums. But from the xnu source it seems that this function has no knowledge of this flag and does nothing to calculate the checksum. _______________________________________________ Do not post admin requests to the list.
