e5db17a1e5 app/testpmd: remove duplicated Rx offload commands
The testpmd application provides two sets of commands for RX offload
flags configuration. The purpose of this patch is to eliminate this
duplication by removing the old set of commands:
“port config all crc-strip|scatter|rx-cksum|rx-timestamp|hw-vlan|
hw-vlan-filter|hw-vlan-strip|hw-vlan-extend on|off”

The other commands set that can be used instead in order to enable
or disable the same RX offloading flags on all RX queues of a port is:
"port config <port_id> rx_offload crc_strip|scatter|ipv4_cksum|
udp_cksum|tcp_cksum|timestamp|vlan_strip|vlan_filter|vlan_extend on|off"

This patch also fixes the "drop-en" command, which enables packets
dropping on all RX queues of all ports when no receive buffers available
“port config all drop-en on|off”

54dcfdee85 drivers/raw: standardize naming
The driver names for rawdevs were both different in make and meson builds
and were non-standard in the make version in that some included "rawdev" in
the name while others didn't.

Therefore, for global consistency of naming, we can use "rte_rawdev" rather
than "rte_pmd" for the prefix for the libraries. While most other driver
categories use "rte_pmd" as a prefix, there is precedent for this in the
mempool drivers use "rte_mempool" as a prefix.

2579543f60 net/mlx5: handle LRO packets in regular Rx queue
When LRO offload is configured in Rx queue, the HW may coalesce TCP
packets from same TCP connection into single packet.

In this case the SW should fix the relevant packet headers because
the HW doesn't update them according to the new created packet
characteristics but provides the update values in the CQE.

Add update header code to the regular Rx burst function to support LRO
feature.

Make sure the first mbuf has enough space to include each TCP header,
otherwise the header update may cross mbufs what complicates the
operation too match.
