It is cleared by graceful_start. If it is already set before calling graceful_stop, then that means that dtsec_isr set it. In that case, we will not set GRS nor will we clear it (which seems like a bug?). For GTS the logic is similar, except that there is no one else messing with this bit (so we will always set and clear it). Simplify the logic by always setting/clearing GRS/GTS. This is less racy that the previous behavior, and ensures that we always end up clearing the bits. This can of course clear GRS while dtsec_isr is waiting, but because we have already done our own waiting it should be fine. This is the last user of enum comm_mode, so remove it.

We still need the resource to get the end address, but we can use a single function call to get both at once. While we're at it, use platform_get_mem_or_io and devm_request_resource to map the resource. I think this is the more "correct" way to do things here, since we use the pdev resource, instead of creating a new one. It's still a bit tricky, since we need to ensure that the resource is a child of the fman region when it gets requested. Signed-off-by: Sean Anderson Acked-by: Camelia Groza Signed-off-by: David S.

This is a bit unusal, since usually the DPAA driver calls into the FMAN driver, but here we do the opposite. We need to add a netdev to struct mac_device for this, but it will soon live in the phylink config. I haven't tested this extensively, but it doesn't seem to break anything. We could possibly optimize this a bit by keeping track of the last rate, but for now we just update every time. 10GEC probably doesn't need to call into this at all, but I've added it for consistency.

Those functions will be removed by a separate patch once this page pool solution is accepted. - fec_enet_new_rxbdp - fec_enet_copybreak The following are the comparing result between page pool
