Maybe it's a good idea to add more information in the above text about RoCE and to change the above text such that people are invited to learn more about RDMA ? As an example, this is how the PPPOL2TP Kconfig entry looks like: config PPPOL2TP tristate "PPP over L2TP (EXPERIMENTAL)" depends on EXPERIMENTAL && L2TP && PPP help Support for PPP-over-L2TP socket family. L2TP is a protocol used by ISPs and enterprises to tunnel PPP traffic over UDP tunnels. L2TP is replacing PPTP for VPN uses.
