sfc: Extend struct efx_tx_buffer to allow pushing option descriptors
The TX path firmware for EF10 supports 'option descriptors' to control offloads and various other features. Add a flag and field for these in struct efx_tx_buffer, and don't treat them as DMA descriptors on completion. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
