Removed DEV_RX_OFFLOAD_CRC_STRIP offload flag. Without any specific Rx offload flag, default behavior by PMDs is to strip CRC. PMDs that support keeping CRC should advertise DEV_RX_OFFLOAD_KEEP_CRC Rx offload capability. Applications that require keeping CRC should check PMD capability first and if it is supported can enable this feature by setting DEV_RX_OFFLOAD_KEEP_CRC in Rx offload flag in rte_eth_dev_configure() Signed-off-by: Ferruh Yigit <ferruh.yigit@intel.com> Acked-by: Tomasz Duszynski <tdu@semihalf.com> Acked-by: Shahaf Shuler <shahafs@mellanox.com> Reviewed-by: Maxime Coquelin <maxime.coquelin@redhat.com> Acked-by: Jan Remes <remes@netcope.com> Acked-by: Jerin Jacob <jerin.jacob@caviumnetworks.com> Acked-by: Hyong Youb Kim <hyonkim@cisco.com>
