    sfc: de-indirect TSO handling · 1679c72c
    Edward Cree authored
    Remove the tx_queue->handle_tso function pointer, and just use
     tx_queue->tso_version to decide which function to call, thus removing
     an indirect call from the fast path.
    Instead of passing a tso_v2 flag to efx_mcdi_tx_init(), set the desired
     tx_queue->tso_version before calling it.
    In efx_mcdi_tx_init(), report back failure to obtain a TSOv2 context by
     setting tx_queue->tso_version to 0, which will cause the TX path to
     use the GSO-based fallback.
