[Intel-wired-lan] [PATCH iwl-next v10 08/14] iavf: periodically cache PHC time

2024-08-21 Thread Wojciech Drewek
From: Jacob Keller The Rx timestamps reported by hardware may only have 32 bits of storage for nanosecond time. These timestamps cannot be directly reported to the Linux stack, as it expects 64bits of time. To handle this, the timestamps must be extended using an algorithm that calculates the co
