Daisuke Matsuda d7c71f93cf RDMA/rxe: Prevent faulty rkey generation ... [ Upstream commit 1aefe5c177c1922119afb4ee443ddd6ac3140b37 ] If you create MRs more than 0x10000 times after loading the module, responder starts to reply NAKs for RDMA/Atomic operations because of rkey violation detected in check_rkey(). The root cause is that rkeys are incremented each time a new MR is created and the value overflows into the range reserved for MWs. This commit also increases the value of RXE_MAX_MW that has been limited unlike other parameters.
