Driver version upgrade is connected with support for the new device fetures, like Tx drops reporting or disabling meta caching. Moreover, the driver configuration from the sysctl was reworked to provide safer and better flow for configuring: * number of IO queues (new feature), * drbr size on Tx, * Rx queue size. Moreover, a lot of minor bug fixes and improvements were added. Copyright date in the license of the modified files in this release was updated to 2020.
