[openib-general] re the core network changes to support network event notification

[Or Gerlitz]

Steve,

Tracking in the netdev archive the threads related to the netevents 
patch, i have noted that you were attempting to add support for two 
"netlink update events" (RTM_NEIGHUPD RTM_ROUTEUPD) but eventually the 
patch that was merged by Dave (round 5) did not include these events.

Did you had any spcial reason to drop them?  is it correct that the
merged code does implement a framework for adding them later?

Can you spare few words about the differences from a **kernel** consumer
point of view between being a direct netevent vs netlink consumer?

I guess IPoIB code would be able to take advantage of RTM_NEIGHUPD netlink event
or a netevents based filter to remove the data path memcmp on the neigh HA address.

thanks,

Or.

Sure.
