Berkeley Packet Filter filtering capabilities are normally handled
by an interpreter. This option allows kernel to generate a native
code when filter is loaded in memory. This should speedup
- packet sniffing (libpcap/tcpdump). Note : Admin should enable
- this feature changing /proc/sys/net/core/bpf_jit_enable
+ packet sniffing (libpcap/tcpdump).

+ Note, admin should enable this feature changing:
+ /proc/sys/net/core/bpf_jit_enable
+ /proc/sys/net/core/bpf_jit_harden (optional)
