92 * Added support for the ``RTE_ETH_DEV_CLOSE_REMOVE`` flag.
94 * **Added cryptodev asymmetric session-less operation.**
96 Added session-less option to cryptodev asymmetric structure. It works the same
97 way as symmetric crypto, corresponding xform is used directly by the crypto op.
99 * **Added Marvell NITROX symmetric crypto PMD.**

121 * **Enabled Single Pass GCM acceleration on QAT GEN3.**
123 Added support for Single Pass GCM, available on QAT GEN3 only (Intel
124 QuickAssist Technology C4xxx). It is automatically chosen instead of the
125 classic 2-pass mode when running on QAT GEN3, significantly improving
126 the performance of AES GCM operations.
128 * **Updated the Intel QuickAssist Technology (QAT) compression PMD.**
130 Added stateful decompression support in the Intel QuickAssist Technology PMD.
131 Please note that stateful compression is not supported.

135 Added a command line option to dpdk-test-compress-perf tool to allocate
136 and use memory zones as external buffers instead of keeping the data directly
139 * **Introduced FIFO for NTB PMD.**
141 Introduced FIFO for NTB (Non-transparent Bridge) PMD to support
142 packet based processing.
144 * **Added eBPF JIT support for arm64.**

168 in order to enable or disable Rx offloading on all Rx queues of a port is::
170 port config <port_id> rx_offload crc_strip|scatter|
171 ipv4_cksum|udp_cksum|tcp_cksum|timestamp|
172 vlan_strip|vlan_filter|vlan_extend on|off
