From: Leon Romanovsky <leonro@xxxxxxxxxxxx> Changelog: v0->v1: * Added patch to bring latest rdma_netlink.h. * Squashed together patches with cmake function to create rename utility and utility patches. * Lowered number of udev rule to be consistent with other persistent naming rules. * changed vendor name with technology it is using. e.g. mlxp0s12f4 -> rocep0s12f4. * Changed default to be NETLINK_FALLBACK. * Excluded virtual devices from renaming policy. * Added documentation. -------------------------------------------------------------------------- Hi, This series introduces RDMA stable and predictable names in similar way to netdev stack. We generalize the naming scheme for RDMA devices, so users will always see names based on topology/GUID information. Such naming scheme has big advantage that the names are fully automatic, fully predictable and they stay fixed even if hardware is added or removed (i.e. no reenumeration takes place) and that broken hardware can be replaced seamlessly. Right now, we are supporting two schemes: based on PCI location and based on system image GUID information.
