From: Rahul Bhansali <rbhansali@marvell.com>

For small packets less than 55 bytes, SQ error interrupts are
observed.
When checksum offload flag is enabled and mbuf ol_flags are not
set, then default L3 type will be set to IPv6 in vector
processing. Based on this, HW will still validate for minimum
header size and generate send header error if mismatch.

To address this, will set default L3 type to none. Mbuf ol_flags
RTE_MBUF_F_TX_IPV6 will set with offload feature TSO or L4
checksum only, so handled in corresponding routine.

Fixes: f71b7dbbf04b ("net/cnxk: add vector Tx for CN10K")
