我在笔记本电脑上启动了 Fedora 33，我注意到一些加载的模块与某些 Chelsio T4/T5 适配器上的整个 Infiniband 堆栈相关。这是 lsmod 输出的示例：
ib_isert 53248 0
iscsi_target_mod 364544 1 ib_isert
ib_iser 49152 0
ib_srpt 69632 0
target_core_mod 417792 3 iscsi_target_mod,ib_srpt,ib_isert
ib_srp 69632 0
scsi_transport_srp 32768 1 ib_srp
ib_ipoib 143360 0
rdma_ucm 32768 0
ib_umad 36864 0
iw_cxgb4 258048 0
ib_uverbs 159744 2 iw_cxgb4,rdma_ucm
rdma_cm 118784 7 iw_cxgb4,rpcrdma,ib_srpt,ib_srp,ib_iser,ib_isert,rdma_ucm
iw_cm 57344 1 rdma_cm
ib_cm 65536 4 rdma_cm,ib_ipoib,ib_srpt,ib_srp
ib_core 397312 13 rdma_cm,ib_ipoib,iw_cxgb4,rpcrdma,ib_srpt,ib_srp,iw_cm,ib_iser,ib_umad,ib_isert,rdma_ucm,ib_uverbs,ib_cm
这很令人惊讶，因为我的笔记本电脑没有任何类似的硬件。这是 lspci 的输出：

有人能解释一下吗？
谢谢。
