They are not updated.
Reminder for following PMDs: - fm10k - sfc - virtio There are two new eth_dev_ops: rx_descriptor_status tx_descriptor_status "rx_descriptor_status" replaces "rx_descriptor_done" It is suggested to switch to new one, and implement tx_descriptor_status Thanks, ferruh >> If the new API is accepted, the descriptor_done() can be deprecated, >> and examples/l3fwd-power will be updated to. > > Applied, thanks > > Next steps: > - implement it in other drivers > - deprecate descriptor_done API > > Ferruh, please, could you check with drivers maintainers? > Thanks >
