[dpdk-dev] [PATCH 3/5] ixgbe: not 'DISABLE' may make confuse, change RTE_IXGBE_RX_OLFLAGS_DISABLE=n to RTE_IXGBE_RX_OLFLAGS_ENABLE=y

[Cunming Liang]

RTE_IXGBE_RX_OLFLAGS_ENABLE gives a hint whick keeping packet type in RX ol_flags or not.
By default it is set to update ol_flags in RX mbuf header.
If unset it, will gain addtional performance, but will lose packet type information.
