> From: Bartosz Golaszewski <bgolaszew...@baylibre.com> > > During development we tried to make the interrupt handling as fine-grained > as possible with TX and RX interrupts being disabled/enabled independently > and the counter registers reset from workqueue context. > > Unfortunately after thorough testing of current mainline, we noticed the > driver has become unstable under heavy load. While this is hard to > reproduce, it's quite consistent in the driver's current form. > > This patch proposes to go back to the previous approach of doing all > processing in napi context with all interrupts masked in order to make the > driver usable in mainline linux. This doesn't impact the performance on > pumpkin boards at all and it's in line with what many ethernet drivers do > in mainline linux anyway. > > At the same time we're adding a FIXME comment about the need to improve > the interrupt handling. > > Fixes: 8c7bd5a454ff ("net: ethernet: mtk-star-emac: new driver") > Signed-off-by: Bartosz Golaszewski <bgolaszew...@baylibre.com> Applied.
