Subject: [PATCH net-next v2 2/3] net: phy: qcom: qca808x: Support PHY
 counter

Enable CRC checking for received and transmitted frames, and configure
counters to clear after being read within config_init() for accurate
counter recording. Additionally, add PHY counter operations and integrate
shared functions.
