This patch fix the debug message format. This patch changes to the commit f160a2d0: net: cpmac: dynamic debug fixes When we use pr_debug()/netdev_dbg() new lines are inserting in b/w the values. The format when i use the printk() These formats used in skb dump and reg dump. This functions called from the entire code. So this will be enabled all the lines.

Both transmit and receive use the same infrastructure for calculating the packet timestamp. Rather than duplicating the code, provide a function to do this common work. Model this function in the Intel e1000e version which avoids calling ns_to_ktime() within the spinlock; the spinlock is critical for timecounter_cyc2time() but not ns_to_ktime().

Clear any pending receive interrupt before we process a pending packet. This helps to avoid any spurious interrupts being raised after we have fully cleaned the receive ring, while still allowing an interrupt to be raised if we receive another packet. The position of this is critical: we must do this prior to reading the next packet status to avoid potentially dropping an interrupt when a packet is still pending.

As of "better implementation of iMX6 ERR006358 quirk", we no longer have a requirement for a delayed work. Moreover, the work is now only used for timeout purposes, so the timeout flag is also pointless - we set it each time we queue the work, and the work clears it. Replace the fec_enet_delayed_work struct with a standard work_struct, resulting in simplified timeout handling code.

Using a (delayed) workqueue for ERR006358 is not correct - a work queue is a single-trigger device. Once the work queue has been scheduled, it can't be re-scheduled until it has been run. This can cause problems - with an appropriate packet timing, we can end up with packets queued, but not sent by the hardware, resulting in the transmit timeout firing. Re-implement this as per the workaround detailed in the ERR006358 documentation - if there are packets waiting to be sent when we service the transmit ring, and we see that the transmitter is not running, kick the transmitter to run the pending entries in the ring. Testing here with a 10Mbit half duplex link sees the resulting iperf TCP bandwidth increase from between 1 to 2Mbps to between 8 to 9Mbps.

Commit cb1ce2ef ("ipv6: Implement automatic flow label generation on transmit") introduced ip6_make_flowlabel, while commit b73c3d0e ("net: Save TX flow hash in sock and set in skbuf on xmit") introduced ip6_set_txhash. ip6_set_tx_hash() uses sk_v6_daddr which references __sk_common.skc_v6_daddr from struct sock_common, which is gated with IS_ENABLED(CONFIG_IPV6). ip6_make_flowlabel() uses the ipv6 member from struct net which is also gated with IS_ENABLED(CONFIG_IPV6).

Many places call fec_restart() with the second parameter being some kind of previously saved duplex value, but only two places call it with some other setting. This is at odds with how the other link settings are handled, and used to be racy before the rtnl locks were added to fec_restart()'s various call paths. Clean this up so all link capabilities are handled in the same way - saved into the fec_enet_private structure, and then fec_restart() acts on those settings.

Changing the features (receive checksumming) requires the hardware to be reprogrammed, and also changes the checks in the receive packet processing. The current implementation has a race - fec_set_features() changes the flags which alter the receive packet processing while the adapter is active, and potentially receiving frames. Only after we've modified the software flag do we shutdown and reconfigure the hardware. This can lead to packets being received and marked with a valid checksum (via CHECKSUM_UNNECESSARY) when the hardware checksum validation has not yet been enabled. We must quiesce the device, then change the software configuration for this feature, and then resume the device if it was previously running. The resulting code structure also allows us to add other configuration features in this path without having to quiesce and resume the network interface and device.

fec_set_features() calls fec_stop() to stop the transmit ring while the transmit queue is still active. This can lead to the transmit ring being restarted by an intervening packet queued for transmission, or by the tx quirk timer expiring. Fix this by disabling NAPI (which ensures that the NAPI handlers are not running), and then take the transmit lock while we stop and restart the adapter (which prevents new packets being queued).

fec_suspend() calls fec_stop() to stop the transmit ring while the transmit packet processing is still active. This can lead to the transmit queue being restarted by an intervening packet queued for transmission, or by the tx quirk timer expiring. Fix this by disabling NAPI first, which will ensure that the NAPI handlers are not running. Then, take the transmit lock before detaching the netif device. This ensures that there are no races with the transmit path - and also ensures that the watchdog won't fire. We can then safely stop the ethernet device itself, knowing that the rest of the driver is safely shut down. On resume, we bring the device back up in reverse order - we restart the device, reattach the device (under the tx lock), and then enable the NAPI handlers. We also need to adjust the close function to cope with this new sequence, so that it's possible to cleanly close down the driver after the hardware fails to resume (eg, due to the regulator_enable() or pinctrl calls in the resume path returning an error.)

This is the second stage to "move calls to quiesce/resume packet processing out of fec_restart()", where we remove calls which are not appropriate to the call site. In the majority of cases, there is no need to detach and reattach the interface as we are holding the queue xmit lock across the reset. The exception to that is in fec_resume(), where we are already detached by the suspend function. Here, we can remove the call to detach the interface. We also do not need to stop the transmit queue. Holding the xmit lock is enough to ensure that the transmit packet processing is not running while we perform our task. However, since fec_restart() always cleans the rings, we call netif_wake_queue() (or netif_device_attach() in the case of resume) just before dropping the xmit lock. This prevents the watchdog firing. Lastly, always call napi_enable() after the device has been reattached in the resume path so that we know that the transmit packet processing is already in an enabled state, so we don't call netif_wake_queue() while detached.
