/* Linux 5.15 commit e945c653c8e97 ("RDMA: Split kernel-only global device
 * caps from uverbs device caps") moved SG_GAPS registration support out of
 * ib_device_attr::device_cap_flags (IB_DEVICE_SG_GAPS_REG) and into the
 * kernel-only ib_device_attr::kernel_cap_flags (IBK_SG_GAPS_REG). The bit
 * value is reused by IB_DEVICE_RAW_MULTI in device_cap_flags, so the field
 * must be selected along with the flag.
