[openib-general] InfiniPath driver announcement

[Roland Dreier]

OK, here's my latest set of patches.  With these changes, userspace
verbs work for me (tested between my one ipath system and a system
with a Mellanox HCA).

I do see a few anomalies, but I don't think they're caused by the
generic uverbs changes I made, since I'm not touching the ipath driver:

 - ibv_rc_pingpong is very very slow (like 26 Mb/sec with default params).

 - ibv_rc_pingpong on loopback doesn't work:

     $ ibv_rc_pingpong  & sleep 1 && ibv_rc_pingpong localhost
     [2] 15790
       local address:  LID 0x000a, QPN 0x00006c, PSN 0xf277e7
       local address:  LID 0x000a, QPN 0x00006d, PSN 0xdcd50e
       remote address: LID 0x000a, QPN 0x00006d, PSN 0xdcd50e
       remote address: LID 0x000a, QPN 0x00006c, PSN 0xf277e7
     Failed status 12 for wr_id 2

 - ibv_ud_pingpong on loopback doesn't work either:

     $ ibv_ud_pingpong & sleep 1 && ibv_ud_pingpong localhost
     [3] 15800
       local address:  LID 0x000a, QPN 0x00006e, PSN 0xa622b2
       local address:  LID 0x000a, QPN 0x00006f, PSN 0x350102
       remote address: LID 0x000a, QPN 0x00006f, PSN 0x350102
       remote address: LID 0x000a, QPN 0x00006e, PSN 0xa622b2
     Couldn't post send

As a bonus, I'm throwing in a patch for libipathoib to fix the RPM
build on Fedora Core 4, and delete the unused ipathoib-abi.h header.
(You'll have to do svn rm yourself to completely kill the file, if you
apply this patch).

BTW, I think it would be a good idea to rename libipathoib to
something like "libipath" (or "libipathverbs" or whatever).  I don't
think we want to put "oib" or "openib" in the name, since in the long
run we're just going to be part of the standard Linux IB (or RDMA)
drivers.
