[dpdk-dev] [PATCH v2 09/17] mbuf: change ol_flags to 32 bits
Olivier Matz
olivier.matz at 6wind.com
Mon May 19 15:56:21 CEST 2014
There is no room to add other offload flags in the current 16 bits
fields. Since we have more room in the mbuf structure, we can change
the ol_flags to 32 bits.
A next commit will add the support of TSO (TCP Segmentation Offload)
which require a new ol_flags, justifying this commit.
Thanks to this modification, another possible improvement (which is not
part of this series) could be to change the checksum flags from:
PKT_RX_L4_CKSUM_BAD, PKT_RX_IP_CKSUM_BAD
to:
PKT_RX_L4_CKSUM, PKT_RX_IP_CKSUM, PKT_RX_L4_CKSUM_BAD, PKT_RX_IP_CKSUM_BAD
in order to detect if the checksum has been processed by hw or not.
