If an RX interrupt > hits before we enabled NAPI then the NAPI callback is never called and > we leave the hardware with RX interrupts disabled, which of course leads > us to never handling received packets. Fix this by moving the interrupt > enable to after we've enable NAPI and the reclaim tasklet. > > Fixes: cd5e41234729 ("dwc_eth_qos: do phy_start before resetting hardware") > Signed-off-by: Rabin Vincent <rabinv@...s.com> > Signed-off-by: Lars Persson <larper@...s.com> Applied.
