    net: sctp: fix checksum marking for outgoing packets · b73c43f8
    Michał Mirosław authored
    Packets to devices without NETIF_F_SCTP_CSUM (including NETIF_F_NO_CSUM)
    should be properly checksummed because the packets can be diverted or
    rerouted after construction. This still leaves packets diverted from
    NETIF_F_SCTP_CSUM-enabled devices with broken checksums. Fixing this
    needs implementing software offload fallback in networking core.
    
    For users of sctp_checksum_disable, skb->ip_summed should be left as
    CHECKSUM_NONE and not CHECKSUM_UNNECESSARY as per include/linux/skbuff.h.
