We observed a high number of rx_discards_phy events on some servers when running `ethtool -S`. However, this important counter is not currently reflected in the /proc/net/dev statistics file, making it challenging to monitor effectively. Since rx_missed_errors represents packets dropped due to buffer exhaustion, it makes sense to include rx_discards_phy in this counter to enhance monitoring visibility. This change will help administrators track these events more effectively through standard interfaces.
