TSO and LRO on Alix boards



  • On the Alix (3 NIC) board is it ok to enable TSO and LRO options under the Advanced Networking page?
    The NIC driver use is VR, but I can't find anywhere if it supports TSO and LRO.

    No TSO or LRO, and you don't want them in most cases anyhow. TSO/LRO help more for the case when the system is a client, not a router.



  • Thank you for the clarification jimp
