just checked that previously connectx4 was have thos disabled:
  ethtool --show-priv-flags enp175s0f0
Private flags for enp175s0f0:
rx_cqe_moder       : on
tx_cqe_moder       : off
rx_cqe_compress    : off
rx_striding_rq     : off
rx_no_csum_complete: off


So now we are on connectx5 and we have enabled - for sure connectx5 
changed cpu load - where i have now max 50/60% cpu where with connectx4 
there was sometimes near 100% with same configuration.
