Mahanta Jambigi b3bab397a3 net/smc: Remove validation of reserved bits in CLC Decline message ... [ Upstream commit cc282f73bc0cbdf3ee7af2f2d3a2ef4e6b19242d ] Currently SMC code is validating the reserved bits while parsing the incoming CLC decline message & when this validation fails, its treated as a protocol error. As a result, the SMC connection is terminated instead of falling back to TCP. As per RFC7609[1] specs we shouldn't be validating the reserved bits that is part of CLC message. This patch fixes this issue. CLC Decline message format can viewed here[2].
