2019-11-08igb/igc: use ktime accessors for skb->tstampJacob Keller1-2/+2
When implementing launch time support in the igb and igc drivers, the skb->tstamp value is assumed to be a s64, but it's declared as a ktime_t value. Although ktime_t is typedef'd to s64 it wasn't always, and the kernel provides accessors for ktime_t values. Use the ktime_to_timespec64 and ktime_set accessors instead of directly assuming that the variable is always an s64. This improves portability if the code is ever moved to another kernel version, or if the definition of ktime_t ever changes again in the future.

2019-11-07net: ethernet: intel: Demote MTU change prints to debugFlorian Fainelli1-3/+2
Changing a network device MTU can be a fairly frequent operation, and failure to change the MTU is reflected to user-space properly, both by an appropriate message as well as by looking at whether the device's MTU matches the configuration. Demote the prints to debug prints by using netdev_dbg(), making all Intel wired LAN drivers consistent, since they used a mixture of PCI device and network device prints before.

2019-10-31igb/igc: Don't warn on fatal read failures when the device is removedLyude Paul1-1/+2
Fatal read errors are worth warning about, unless of course the device was just unplugged from the machine - something that's a rather normal occurrence when the igb/igc adapter is located on a Thunderbolt dock. So, let's only WARN() if there's a fatal read error while the device is still present. This fixes the following WARN splat that's been appearing whenever I unplug my Caldigit TS3 Thunderbolt dock from my laptop: igb 0000:09:00.0 enp9s0: PCIe link lost ------------[ cut here ]------------ igb: Failed to read reg 0x18!

2019-05-28igb/igc: warn when fatal read failure happensFeng Tang1-0/+1
Failed in read the HW register is very serious for igb/igc driver, as its hw_addr will be set to NULL and cause the adapter be seen as "REMOVED". We saw the error only a few times in the MTBF test for suspend/resume, but can hardly get any useful info to debug. Adding WARN() so that we can get the necessary information about where and how it happens, and use it for root causing and fixing this "PCIe link lost issue" This affects igb, igc.
