Regarding SubnetTimeout changes: the code in
drivers/infiniband/core/cache.c already queues a work request after each
port state change. Inside that work request e.g. the P_Key cache is
updated. Would it be acceptable to modify ib_cache_update() such that it
also queries the port attributes and caches these ? Cached port
attributes could e.g. be stored in struct ib_port.
Without looking at details, this at least sounds reasonable.
Sean, can't we have CMA to follow the same practice used in the CM where
we derive the RC QP timeout based on the packet life time retrieved in
path queries? e.g base the cm response time out on this value too?
