r8152: fix flow control issue of RTL8156A
[ Upstream commit 8ceda6d5a1e5402fd852e6cc59a286ce3dc545ee ]
The feature of flow control becomes abnormal, if the device sends a
pause frame and the tx/rx is disabled before sending a release frame. It
causes the lost of packets.
Set PLA_RX_FIFO_FULL and PLA_RX_FIFO_EMPTY to zeros before disabling the
tx/rx. And, toggle FC_PATCH_TASK before enabling tx/rx to reset the flow
control patch and timer. Then, the hardware could clear the state and
the flow control becomes normal after enabling tx/rx.
Besides, remove inline for fc_pause_on_auto() and fc_pause_off_auto().
