Viacheslav Ovsiienko f078ceb6ae net/mlx5: fix Tx doorbell write memory barrier ... As the result of testing it was found that some hosts have the performance penalty imposed by required write memory barrier after doorbell writing. Before 19.08 release there was some heuristics to decide whether write memory barrier should be performed. For the bursts of recommended size (or multiple) it was supposed there were some extra ongoing packets in the next burst and write memory barrier may be skipped (supposed to be performed in the next burst, at least after descriptor writing). This patch restores that behaviour, the devargs tx_db_nc=2 must be specified to engage this performance tuning feature.
