interface: fix the checksum offload in quad loop
Type: fix In quad loop, checksum will be calculated for all four packets, if one packet needs checksum computation, without respecting their respective flags. This patch fixes it. Change-Id: I479b420ba0dcbd178ea4180bf05a0e55a6b13843 Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>
