net: dsa: microchip: add MIB counters support
|
expand
|
From: Tristram Ha <Tristram.Ha@microchip.com> This series of patches is to modify the KSZ9477 DSA driver to read MIB counters periodically to avoid overflow. The MIB counters should be read only when there is link. Otherwise it is a waste of time as hardware never increases the counters. Functions are added to check the port link status so that MIB counters read call is used efficiently. v2 - Create macro similar to readx_poll_timeout to use with switch - Create ksz_port_cleanup function so that variables like on_ports and live_ports can be updated inside it. v1 - Use readx_poll_timeout - Do not clear MIB counters when port is enabled - Do not advertise 1000 half-duplex mode when port is enabled - Do not use freeze function as MIB counters may miss counts Tristram Ha (4): net: dsa: microchip: prepare PHY for proper advertisement net: dsa: microchip: add MIB counter reading support net: dsa: microchip: get port link status net: dsa: microchip: remove unnecessary include headers drivers/net/dsa/microchip/ksz9477.c | 137 +++++++++++++++++---------- drivers/net/dsa/microchip/ksz_common.c | 163 ++++++++++++++++++++++++++++++++- drivers/net/dsa/microchip/ksz_common.h | 27 +++++- drivers/net/dsa/microchip/ksz_priv.h | 14 +-- 4 files changed, 284 insertions(+), 57 deletions(-)
