Subject: r8152: re-schedule napi for tx
From: hayeswang <[email protected]>
[ Upstream commit 248b213ad908b88db15941202ef7cb7eb137c1a0 ]
Re-schedule napi after napi_complete() for tx, if it is necessay.
In r8152_poll(), if the tx is completed after tx_bottom() and before napi_complete(), the scheduling of napi would be lost. Then, no one handles the next tx until the next napi_schedule() is called.
