RE: [Announce] rxe dev tree available (soft RDMAoE)

Hi Sean,

Probably someday. We looked at the ipath driver before writing rxe but the
qib driver came out much later and we haven't really spent any time looking
at it. Currently rxe is written to be standalone and doesn't have an obvious
place to split into pieces. Some of the header files could maybe go into
core. (For example rxe_hdr.h and rxe_opcode.[ch] overlap
include/rdma/ib_pack.h).

The hard parts of the driver are the state machines and they are fairly
specific.

Bob

Is there any commonality that can be shared between rxe and the qlogic
driver?
