Subject: [PATCH 61/72] jme: Fix FIFO flush issue
|
|
|
|
commit ba9adbe67e288823ac1deb7f11576ab5653f833e upstream.
|
|
|
|
Set the RX FIFO flush watermark lower.
|
|
According to Federico and JMicron's reply,
|
|
setting it to 16QW would be stable on most platforms.
|
|
Otherwise, user might experience packet drop issue.
