As for the clearing, in this case, the clearing is done by a command to the hardware - and I believe the hardware does that atomically. However, I could certainly add a spinlock around it if someone sees a need.
No, because then you'd also have to add the spin-lock in the hot path to keep rx/tx threads from accessing counters at the same time. There is no way a patch that hurts performance like this will be accepted, but I'm still hopeful that a patch with zero or very near zero performance impact will be accepted.
