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.
