net: use software GSO for SG+CSUM capable netdevices
If a netdevice does not support hardware GSO, allowing the stack to use GSO anyway and then splitting the GSO skb into MSS-sized pieces as it is handed to the netdevice for transmitting is likely still a win as far as throughput and/or CPU usage are concerned, since it reduces the number of trips through the output path. This patch enables the use of GSO on any netdevice that supports SG. If a GSO skb is then sent to a netdevice that supports SG but does not support hardware GSO, net/core/dev.c:dev_hard_start_xmit() will take care of doing the necessary GSO segmentation in software.
