  • f6e27114a   net: Add a xfrm validate function to validate_xmit_skb ... Browse Code »

    When we do IPsec offloading, we need a fallback for
    packets that were targeted to be IPsec offloaded but
    rerouted to a device that does not support IPsec offload.
    For that we add a function that checks the offloading
    features of the sending device and and flags the
    requirement of a fallback before it calls the IPsec
    output function. The IPsec output function adds the IPsec
    trailer and does encryption if needed.

  • d77e38e61   xfrm: Add an IPsec hardware offloading API ... Browse Code »

    This patch adds all the bits that are needed to do
    IPsec hardware offload for IPsec states and ESP packets.
    We add xfrmdev_ops to the net_device. xfrmdev_ops has
    function pointers that are needed to manage the xfrm
    states in the hardware and to do a per packet
    offloading decision.
