Hello netdev experts,
I am investigating the requirements to support hsr/prp SNMP functions in kernel.
Based on my investigation so far, the kernel include file include/net/snmp.h
defines all of the SNMP MIBS related defines and structures. But the MIBs are
read-only type MIBs. Is there any implementation of read-write MIBs in kernel?
One of the specs for MIBs that are investigating have read-write MIBs and
wondering if we have any precedence of such MIBs implemented in kernel space.
If not, what is the suggested way to implement these MIBs in kernel space?
I assume that to implement read-only MIBs for hsr driver, I need to add
them to snmp.h and use standard Macros in snmp.h to update them from the driver.
Thanks

I did some more research on this, and found some of the (not sure if there is any
in kernel) read-write MIBs are implemented in the net-snmp, where
it communicate using a raw socket and calling an ioctl. Is this the way to go
to implement the read-write MIBs?
Thanks
