[etherlab-users] skipped/unmatched datagrams - at startup - safe to ignore?

I'm experimenting with different NIC to better understand the pros, cons
and tradeoff of different solution. My system has on-board e1000e, and a
PCIe r8169, my test application runs in kernel cycled by hr-timer. I'm
cranking up the frame rate looking how far it will reliably go and
checking dmesg logs.
In all cases, there seems to be an intermediate frame rate where I get
skipped/unmatched datagrams right after inserting my app. module, but
quickly; once the master has found all the slaves (?) no more warnings
show in the logs
I was wondering if it was safe to ignore those skipped/unmatched
warnings? Should I plan some checks in my application to verify the pdo
mapping, sdo config, etc have all been properly applied?
