Hi All,
I am attempting to compile the rss epbf program dpdk and I am getting too
much compilation errors, is there anything specific that I need to
configure when compiling?
I am running the following line:
clang -O2 -emit-llvm -c tap_bpf_program.c -o - | llc -march=bpf
-filetype=obj -o tap_bpf_program.o
I think it is due to some misconfiguration of
The errors I am getting:
