If anyone has any objections, please let me know. ------------------ From: Carolina Jubran [ Upstream commit 5c74195d5dd977e97556e6fa76909b831c241230 ] Previously, the driver incorrectly used rx_dropped to report device buffer exhaustion. According to the documentation, rx_dropped should not be used to count packets dropped due to buffer exhaustion, which is the purpose of rx_missed_errors. Use rx_missed_errors as intended for counting packets dropped due to buffer exhaustion.
