Signed-off-by: Andrew Rybchenko --- It should be applied after [1]. txq_flags are still used in net/sfc to check if legacy application creates Tx queue. If so: - IPv4 and outer IPv4 checksum (if supported) offloads are enabled - TSO is enabled if TCP checksum is not disabled It is required since old TxQ flags do not have means to control it.
