What does 1 mean? Surely not 1 byte MTU :)
IMO a good format would be the MTU value in bytes.
E.g. 512, 1024, 2048, 4096.

scsi/scsi_transport_iscsi.h uses struct mutex and struct list_head,
so while linux/mutex.h and linux/list.h seem to be pulled in indirectly
by one of the headers it includes, the right thing
is to include linux/mutex.h and linus/list.h directly.

Hi,
ibv_modify_qp() fails with return value 22 when I try to open a new CM
connection under load (already ~3000 RDMA connections opened). I tried
to figure out what return value 22 means but could not find it in the
mthca kernel driver.
Any hints? What does return value 22 mean?
I use OFED-1.1

In the socket API, socket options describe what protocol they are
intended for. You can have options that are intended for IP or TCP and
other protocol layers.
We could do some rdma_setopt() interface, and define both transport

This same argument is why IPoIB ARP decisions really have no bearing

I believe a better solution is for everyone to use cached records, if
they exist, with a feedback mechanism from the CM that removes paths on
a connection failure or path migration event.
Ack timeout on an RC QP is also a good indication we should redo the lookup.
