Subject: [PATCH] r8169: disable interrupt source RxOverflow
|
||
|
|
|
||
|
|
Vendor driver calls this bit RxDescUnavail. All we do in the interrupt
|
||
|
|
handler in this case is scheduling NAPI. If we should be out of
|
||
|
|
RX descriptors, then NAPI is scheduled anyway. Therefore remove this
|
||
|
|
interrupt source. Tested on RTL8168h.
