5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Carolina Jubran <cjubran@xxxxxxxxxx>
[ 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.
Fixes: 269e6b3af3bf ("net/mlx5e: Report additional error statistics in get stats ndo")
