Is it safe to just delete "setsockopt(..., PACKET_QDISC_BYPASS, ..." for kernels before 3.14?

[libc0607]

Hi, I'm building OpenIPC (main branch) for Ingenic T31, and it throws a build error in src/tx.cpp and src/tx.hpp like "PACKET_QDISC_BYPASS not defined", which points to:

if(!use_qdisc)
        {
            const int optval = 1;
            if(setsockopt(fd, SOL_PACKET, PACKET_QDISC_BYPASS, (const void *)&optval , sizeof(optval)) !=0)
            {
                close(fd);
                throw runtime_error(string_format("Unable to set PACKET_QDISC_BYPASS: %s", strerror(errno)));
            }
        }

The reason is PACKET_QDISC_BYPASS was introduced in 3.14, and T31 has only 3.10.14 kernel support.

I tried to delete the block above, and then it compiles. So, is it safe to just delete that if I'm not using the traffic shaper features?
