Remove multi-segment packet handling from mlx5_tx_burst_empw() as there's
fallback to regular Tx for such packets.
Signed-off-by: Yongseok Koh <yskoh@mellanox.com>
mlx5_tx_burst_empw() falls back to legacy Tx descriptor for multi-segmented
packets without taking advantage of inlining. In many cases, the 1st
segment can be inlined and this could make device fetch only one segment
instead of two. This helps saving PCIe bandwidth when transmitting out
multi-segmented packets with still using the Enhanced Multi-Packet Send for
other packets.

mlx5_tx_burst() doesn't inline data from the 2nd segment. If there's still

Although granularity of chunks in a mempool is a cacheline, addresses are
extended to align to page boundary for performance reason in device when
registering a MR (Memory Region). This could make some regions overlap,
then can cause Tx completion error due to incorrect LKEY search. If the
error occurs, the Tx queue will get stuck. To avoid it, end address of a
packet segment is used in LKEY search.

There is a school of thought that rte_eth_dev_default_mac_addr_set()
must call the PMD callback first and then save the new MAC address
in dev->data->mac_addrs[0]. If this concept gets approved, it will
break the current approach used in sfc driver as the latter relies
on the assumption that the new MAC address is already contained in
dev->data->mac_addrs[0], and, if adapter restart is needed to make
the HW apply the new address, the outdated value will be retrieved
from dev->data. In order to preclude any possible bugs, this patch
adds device private storage for the up-to-date copy of the address.

The previuse code took a send queue entry size for stamping from the
send queue entry pointed by completion queue entry; This 2 reads were
done per packet in completion stage.

Tx queue, so we can infer that each valid completion entry actually frees
the next fixed number packets.
The descriptors ring holds the send queue entry, so we just can infer
all the completion burst packet entries size by simple calculation and
prevent calculations per packet.

by one time and prevent per packet work queue entry reads and

mlx4 Tx block can handle up to 4 data segments or control segment + up
to 3 data segments. The first data segment in each not first Tx block
must validate Tx queue wraparound and must use IO memory barrier before
writing the byte count.
The previous multi-segment code used "for" loop to iterate over all
packet segments and separated first Tx block data case by "if"
statements.
Use switch case and unconditional branches instead of "for" loop can
optimize the case and prevents the unnecessary checks for each data
segment; This hints to compiler to create optimized jump table.
