Merge branch 'felix-dsa-ethtool-stats'
Vladimir Oltean says: ==================== Standardized ethtool counters for Felix DSA driver The main purpose of this change set is to add reporting of structured ethtool statistics counters to the felix DSA driver (see patch 11/14 for details), as a prerequisite for extending these counters to the eMAC/pMAC defined by the IEEE MAC Merge layer. Along the way, the main purpose has diverged into multiple sub-purposes which are also tackled: - A bug fix patch submitted to "net" has made ocelot->stats_lock a spin lock, which is not an issue currently (all Ocelot switches are MMIO), but will be an issue for Colin Foster who is working on a SPI controlled Ocelot switch. We restore the hardware access to port stats to be sleepable. - PSFP (tc-gate, tc-police) tc-flower stats on Felix use a non-converged procedure to access the hardware counters, although the interface is very similar to what is used for the port counters. Benefit from the logic used for the port counters, which gains us 64-bit tc-flower stats that are resistant to overflows. - Also export the ndo_get_stats64 method used by the ocelot switchdev driver to Felix, so that ifconfig sees something hardware-based as well (but not 100% up to date). - Create a new ocelot_stats.c file which groups everything stats-related together. Along with this, also move some other topic-specific code, like FDB and PTP, out of the main ocelot.c. - Minimize the lines of code for the stats layout definitions. These changes alone cause the patch set to have an overall reduction of lines of code in the driver, even though we are adding new functionality as well. Tested the port counters with lockdep and friends, with some garden-variety traffic (ping, iperf3) and the PSFP counters with tools/testing/selftests/drivers/net/ocelot/psfp.sh. ==================== Signed-off-by: David S.
