PTFs might be required for toleration support or exploitation of z15 features and functions. b. Support statement varies based on Linux on Z distribution and release. c. By using VLANs. d. On z15, the CHPID statement of HiperSockets devices requires the keyword VCHID.  Therefore, the z15 IOCP definitions must be migrated to support the HiperSockets definitions  (CHPID type IQD). VCHID specifies the virtual channel identification number that is associated  with the channel path (valid range is 7E0 - 7FF). VCHID is not valid on IBM Z servers before  z13. e. Applicable to guest operating systems. f. Shared Memory Communications - Direct Memory Access. g. SMC-R and SMC-D are supported on Linux kernel; see:  https://linux-on-z.blogspot.com/p/smc-for-linux-on-ibm-z.html h. Remote Direct Memory Access (RDMA) over Converged Ethernet. i. Linux can also use RocE Express as a standard NIC (Network Interface Card) for Ethernet. j. Does not require a peer OSA. Chapter 7. Operating system support  271
