The counter variable in iavf_clean_tx_irq starts out negative and climbs to 0. So allocating it as u16 is actually a really bad idea that just happens to work because the value underflows and overflows consistently on most architectures.

While data pass suspend, reuse of rx descriptors can be disabled using channel state & lock from cpdma layer. For this, submit to a channel has to be disabled using state != "not active" under lock, what is done with this patch. The same submit is used to fill rx channel while ndo_open, when channel is idled, so add idled submit routine that allows to prepare descs for the channel. All this simplifies code and helps to avoid dormant mode usage and send packets only to active channels, avoiding potential race in later on changes. Also add missed sync barrier analogically like in other places after stopping tx queues. Signed-off-by: NIvan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: NDavid S.

Change stmmac_mdio_reset() to use device_property_read_u32_array() instead of of_property_read_u32_array(). This is meant as a cleanup because we can drop the struct device_node variable. Also it will make it easier to get rid of struct stmmac_mdio_bus_data (or at least make it private) in the future because non-OF platforms can now pass the reset delays as device properties. No functional changes (neither for OF platforms nor for ones that are not using OF, because the modified code is still contained in an "if (priv->device->of_node)").

A simplified version of the existing code looks like this: if (priv->device->of_node) { struct device_node *np = priv->device->of_node; if (!np) return 0; The second "if" never evaluates to true because the first "if" checks for exactly the opposite. Drop the redundant check and early return to make the code easier to understand. No functional changes intended.

NAPI tx mode improves TCP behavior by enabling TCP small queues (TSQ). TSQ reduces queuing ("bufferbloat") and burstiness. Previous measurements have shown significant improvement for TCP_STREAM style workloads. Such as those in commit 86a5df14 ("Merge branch 'virtio-net-tx-napi'"). There has been uncertainty about smaller possible regressions in latency due to increased reliance on tx interrupts. The above results did not show that, nor did I observe this when rerunning TCP_RR on Linux 5.1 this week on a pair of guests in the same rack. This may be subject to other settings, notably interrupt coalescing. In the unlikely case of regression, we have landed a credible runtime solution. Ethtool can configure it with -C tx-frames [0|1] as of commit 0c465be1 ("virtio_net: ethtool tx napi configuration"). NAPI tx mode has been the default in Google Container-Optimized OS (COS) for over half a year, as of release M70 in October 2018, without any negative reports.

Presently the HNS driver enables the HNS H/W error interrupts after the dev initialization is completed. However some exceptions such as NCSI errors can occur when the network port driver is not loaded and those errors required reporting to the BMC. Therefore the firmware enabled all the HNS ras error interrupts before the driver is loaded. And in some cases, there will be some H/W errors remained unclear before reboot. Thus the HNS driver needs to process and recover those hw errors occurred before HNS driver is initialized. This patch adds processing of the HNS hw errors(RAS and MSI-X) which occurred before the driver initialization. For RAS, because they are enabled by firmware, so we can detect specific bits, then log and clear them. But for MSI-X which can not be enabled before open vector0 irq, we can't detect the specific error bits, so we just write 1 to all interrupt source registers to clear.

However the rest_event would be called later from the slot_reset callback. This can cause issue of using the wrong reset_level if a high priority reset request occur before the slot_reset is called.
