    ixv: Advertise SCTP checksum offload
    
    The shared ixgbe transmit path already creates SCTP context
    descriptors, and the hardware exposes the same checksum capability to
    VFs.  Advertise it through iflib as the PF driver does.
    
    (cherry picked from commit 4a13b8a7c5611059384309fdebad8e0fb49a73c2)
