Subject: net/bnxt: fix Tx with multiple mbuf
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b2a4a69f7b663f712437c7c31dc0916ffe4ad84b;p=dpdk.git

net/bnxt: fix Tx with multiple mbuf

When using multi-mbuf to xmit large packets, we need to use total
packet lengths (sum of all segments) to set txbd->flags_type.
Packets will not be sent when using tx_pkt->data_len(The first
segment of packets).

Fixes: 6eb3cc2294fd ("net/bnxt: add initial Tx code")
