Kristof Provost 83699dfd09 vtnet: Support jumbo frames without TSO/GSO ... Currently in Virtio driver without TSO/GSO features enabled, the max scatter gather segments for the TX path can be 4, which limits the support for 9K JUMBO frames. 9K JUMBO frames results in more than 4 scatter gather segments and virtio driver fails to send the frame down to host OS. With TSO/GSO feature enabled max scatter gather segments can be 64, then 9K JUMBO frames are fine, this is making virtio driver to support JUMBO frames only with TSO/GSO. Increasing the VTNET_MIN_TX_SEGS which is the case for non TSO/GSO to 32 to support upto 64K JUMBO frames to Host.
