Subject: net/pcap: fix byte stats for drop Tx
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=cec222d6e55d9bd15eff7fbbf45464c0c6a941c0;p=dpdk.git

net/pcap: fix byte stats for drop Tx

Drop Tx path in pcap is Tx that just drops the packets, which is used
for the case only Rx from a pcap file is requested/matters.

The byte stats was calculated using first mbuf segment, which gives
wrong values for multi segmented mbufs, updated to use packet length
instead.

Bugzilla ID: 597
Fixes: a3f5252e5cbd ("net/pcap: enable infinitely Rx a pcap file")
