Subject: [PATCH] net/bnxt: fix Tx with multiple mbuf

[ upstream commit b2a4a69f7b663f712437c7c31dc0916ffe4ad84b ]

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")
