That should teach me to include the .config file.
However, it's not difficult to recreate.
CONFIG_INFINIBAND_ADDR_TRANS=n because it depends on INFINIBAND && INET,
(INET being TCP/IP) which =n.

NET_9P_RDMA depends on NET && NET_9P && INFINIBAND && EXPERIMENTAL, but this problem
config has NET=y and INET=n.  And NET != INET.

So INFINIBAND_ADDR_TRANS could depend on NET instead of INET (maybe; I don't
know what interfaces it really needs) or NET_9P_RDMA could depend on INET &&
<rest of list>.  But I don't know which change makes the most sense, or if
some other change does.

HTH.  config attached.
