Build Update for istokes/ovs
-------------------------------------

Build: #713
Status: Errored

Duration: 1 hr, 49 mins, and 51 secs
Commit: 66a24c1 (mseg)
Author: Tiago Lam
Message: dp-packet: Fix data_len handling multi-seg mbufs.

When a dp_packet is from a DPDK source, and it contains multi-segment
mbufs, the data_len is not equal to the packet size, pkt_len. Instead,
the data_len of each mbuf in the chain should be considered while
distributing the new (provided) size.

To account for the above dp_packet_set_size() has been changed so that,
in the multi-segment mbufs case, only the data_len on the last mbuf of
the chain and the total size of the packet, pkt_len, are changed. The
data_len on the intermediate mbufs preceeding the last mbuf is not
changed by dp_packet_set_size(). Furthermore, in some cases
dp_packet_set_size() may be used to set a smaller size than the current
packet size, thus effectively trimming the end of the packet. In the
multi-segment mbufs case this may lead to lingering mbufs that may need
freeing.

__dp_packet_set_data() now also updates an mbufs' data_len after setting
the data offset. This is so that both fields are always in sync for each
mbuf in a chain.
