In testpmd the rte_port->tx_ol_flags flag was used in 2 incompatible manners: - sometimes used with testpmd specific flags (0xff for checksums, and bit 11 for vlan) - sometimes assigned to m->ol_flags directly, which is wrong in case of checksum flags This commit replaces the hardcoded values by named definitions, which are not compatible with mbuf flags. The testpmd forward engines are fixed to use the flags properly. Signed-off-by: Olivier Matz <olivier.matz@6wind.com> Acked-by: Konstantin Ananyev <konstantin.ananyev@intel.com>
