SNMP read-write MIBs

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.

+ David, Eric,

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
