Hi Dotan.

I too had looked in libsdp and found no epoll implementation. I
thought I'd ask tho, because it could be that the direct
implementation of SDP (by using AF_INET_SDP for socket() calls) causes
epoll event notifications within the kernel itself - ie without the
need to use libsdp.

I've looked in the ofa_kernel package and found no reference to epoll
so it doesn't look like its implemented there either, but don't know
if I'm looking in the right place.

For now I think I will be restrained to using TCP over infiniband
because I don't like the idea of mixing epoll with select() in my
applications event loop. But still, epoll() coupled with AF_INET_SDP
would be better.

Many thanks
