[dpdk-dev] [PATCH v2 14/23] net/bnxt: fix Tx with multiple mbuf

[Ajit Khaparde]

From: Xiaoxin Peng <xiaoxin.peng at broadcom.com>

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")
