卸载XDP程序到NetRonome Smart NIC不支持的功能

我正在尝试将一个小的EBPF程序卸载到使用地图的NIC。我可以在哈希地图中查找元素，但是当我添加命令bpf_map_update_elem时，我会在尝试加载时会恢复错误。

14: (85) call bpf_map_update_elem#2
[nfp] map_update: not supported by FW

我正在运行的驱动程序：

$ ethtool -i $ETHNAME
driver: nfp
version: 5.15.0-27-generic
firmware-version: 0.0.3.5 0.31 bpf-2.0.6.124 ebpf
expansion-rom-version:
bus-info: 0000:06:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no

根据应支持此功能。有人找到了解决方案吗？

I'm trying to offload a small EBPF program to the NIC that uses a map. I can lookup elements in the hash map, but when I add the command bpf_map_update_elem I get back an error when I attempt to load.

14: (85) call bpf_map_update_elem#2
[nfp] map_update: not supported by FW

The driver I'm running:

$ ethtool -i $ETHNAME
driver: nfp
version: 5.15.0-27-generic
firmware-version: 0.0.3.5 0.31 bpf-2.0.6.124 ebpf
expansion-rom-version:
bus-info: 0000:06:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no

According to https://www.netronome.com/media/documents/UG_Getting_Started_with_eBPF_Offload.pdf this function should be supported.
Has anybody found a solution?
