Hi All,


With the latest Oracle EL9 with DPDK 22.11.1 version, I modified the RSS eBPF C program and generated the structure of a C array in the 'tap_bpf_insns.h' file.
This array is in eBPF bytecode instructions format. However, even with new bytecode eBPF failed to load TAP PMD with the following error:

rss_add_actions(): Failed to load BPF section 'l3_l4' (7): Argument list too long.
net_failsafe: Failed to create a flow on sub_device 1."


Currently we are using below kernel:
5.15.0 #9 SMP PREEMPT
x86_64 GNU/Linux


How to resolve these errors ?

Regards,
Anudattu
