Description: IB/core: Don't resolve passive side RoCE L2 address in CMA REQ handler
References:
Notes:
 From oss-sec:
 Linux kernel built with the InfiniBand communication link(CONFIG_INFINIBAND)
 along with the support for Remote Direct Memory Access(RDMA) over Convered
 Ethernet(RoCE), is vulnerable to a crash caused by invalid memory access.
 It occurs while trying to resolve RoCE L2 address on the server side.
 A remote unprivileged user/program could use this flaw to crash the kernel,
 resulting in DoS.
