net: qualcomm: rmnet: Add support for GSO
Real devices may support scatter gather(SG), so enable SG on rmnet devices to use GSO. GSO reduces CPU cycles by 20% for a rate of 146Mpbs for a single stream TCP connection. Signed-off-by: Subash Abhinov Kasiviswanathan <subashab@codeaurora.org> Signed-off-by: David S. Miller <davem@davemloft.net>
