The ICSSG firmware maintains set of stats called PA_STATS. Currently the driver only dumps 4 stats. Add support for dumping more stats. The offset for different stats are defined as MACROs in icssg_switch_map.h file. All the offsets are for Slice0. Slice1 offsets are slice0 + 4. The offset calculation is taken care while reading the stats in emac_update_hardware_stats(). The statistics are documented in Documentation/networking/device_drivers/icssg_prueth.rst Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: MD Danish Anwar <danishanwar@ti.com> Link: https://patch.msgid.link/20250424095316.2643573-1-danishanwar@ti.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
