87 Updated the Intel ice driver with new features and improvements, including:
89 * Added support for device-specific DDP package loading.
90 * Added support for handling Receive Flex Descriptor.
91 * Added support for protocol extraction on per Rx queue.
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.**

110 * **Enabled Single Pass GCM acceleration on QAT GEN3.**
112 Added support for Single Pass GCM, available on QAT GEN3 only (Intel
113 QuickAssist Technology C4xxx). It is automatically chosen instead of the
114 classic 2-pass mode when running on QAT GEN3, significantly improving
115 the performance of AES GCM operations.
117 * **Updated the Intel QuickAssist Technology (QAT) compression PMD.**
119 Added stateful decompression support in the Intel QuickAssist Technology PMD.
120 Please note that stateful compression is not supported.

150 The testpmd commands set that can be used instead
151 in order to enable or disable Rx offloading on all Rx queues of a port is::
153 port config <port_id> rx_offload crc_strip|scatter|
154 ipv4_cksum|udp_cksum|tcp_cksum|timestamp|
155 vlan_strip|vlan_filter|vlan_extend on|off
