I also don't think an API change is required in the approach I am
planning to take. It's in user_mad in how it allocates memory and copies
into it as well as the underlying mad layer for supporting more than 1
sgl entry. If you want to take the ball on this, you/Michael are welcome
to submit patches to both of these along these lines. Sean can comment
for himself on this.
An API change shouldn't be necessary. The plan to support large sends was to
change how the void *mad pointer in struct ib_mad_send_bug is used. Currently,
it references a single data buffer. The fix is to have it reference a list of
buffers for large transfers. See:
http://openib.org/pipermail/openib-general/2005-October/012723.html
for more details.
And yes, a patch for this would be great. Otherwise, I will eventually get to
this, but it may be a few weeks before it bumps up high enough on my priority list.
