Patch 1 fixes the transmit burst loop in mana_tx_burst() to terminate with break instead of continue upon packet errors. Under the DPDK rte_eth_tx_burst() API contract, callers expect a contiguous prefix of transmitted packets. Skipping a packet caused unsent packets to be treated as unsent and freed by caller, followed by a second free upon hardware CQE arrival. Patch 2 adds support for hardware TCP Segmentation Offload (TSO), formatting SGL entries with packet headers in SGE0, handling GDMA work request flags, advertising RTE_ETH_TX_OFFLOAD_TCP_TSO, and updating the mana driver feature table.
