[PATCH net 0/3] netdevsim: psp: fix issues with stats collection

[Daniel Zahka]

It has come to my attention via a sashiko review of my net-next series
for aes-gcm in netdevsim [1] that there were preexisting issues with
netdevsim's implementation of psp statistics.

API usage issues:
1. not calling u64_stats_init() on the u64_stats_sync object during
   init
2. not serializing usage of the writer side API during stats update

Logical Bugs:
1. We were incrementing rx stats on the sending devices stats
   counters.
