A key component of the resilient hashing algorithm is the hash buckets' activity. If a bucket is active, it will not be populated with a new nexthop in order not to break existing flows. Therefore, in order to easily and thoroughly test the algorithm, we need to be in full control over the reported activity. Add a debugfs interface that allows user space to have netdevsim report a nexthop bucket within a resilient nexthop group as active. For example: # echo 10 23 > /sys/kernel/debug/netdevsim/netdevsim10/fib/nexthop_bucket_activity Will mark bucket 23 in nexthop group 10 as active.
