So it si recomme= nded to have ASLR disabled.=20 2. with `Using DPDK20.02 with ASLR enabled, Segmentaion fault takes place.`, but the recommendation from SPP team is to disable. 3. with `PDK20.05, this does not happen with the same test conditions.` whi= ch means ASLR is enabled. My recommendation is disabling ASLR for `rte_eth_rx/tx` is not the right approach. If we agree, then SPP and documentation should not state to dsiable ASLR --=20 You are receiving this mail because: You are on the CC list for the bug.=
