Hi All,

I have enabled the bionic-proposed repo as described in link. OVS-master is used for testing, containing the build-time binutils bug check as described above.

1) Can confirm that old binutils version (2.30-21ubuntu1~18.04.3) had issue, and OVS was correctly DISabling AVX512.

2) Can confirm that with -proposed binutils (2.30-21ubuntu1~18.04.4), OVS build system is correctly ENabling AVX512 support, as linker checks are passing.

After the configure step, I have tested OVS, running traffic and enabling the AVX512 optimizations. It is working as expected, with AVX512 instructions running in the datapath.

I believe you have already added the "verification-done" and bionic versions Christian, so I'll not change the status... please let me know if I misunderstood the process.

Thanks Robie & Christian for your support on this issue! -Harry
