Reference code that shows how to get a packet's timestamp out of cxgbe(4). Disabled by default because we don't have a standard way today to pass this information up the stack. The timestamp is 60 bits wide and each increment represents 1 tick of the T4's core clock. As an example, the timestamp granularity is ~4.4ns for this card: # sysctl dev.t4nex.0.core_clock dev.t4nex.0.core_clock: 228125 MFC after: 1 week |
