From: Yishai Hadas yish...@mellanox.com
This patch does refactoring of the IB core umem code and vendor drivers to use
linear SG table instead of chunk list. With this change the relevant code
becomes
more clear, no need for nested loops to build and use umem.
The patch includes: umem changes

Non-contiguous buffers are a well known problem/challenge for RDMA
transports, each handles them differently: iSER uses bounce buffers,
SRP registers multiple contiguous regions.
To be precise, we do it only on very special cases, normally the payload

Didn't understand why should it matter where the copy is done (iser/block)?
In the Linux kernel community it is considered important to avoid code
duplication. Hence the proposal to keep code that copies data

Thanks for narrowing this down, I see your point, however the solution I
propose if to remove this copy altogether... for those rare cases where
fast-registration can't be done -- in SRP I think the code goes

yep, this is legacy code which isn't much of use over the last years

Hi Sean,
I just noted you've tagged librdmacm 1.0.18 last week, but there was no
announce email, was it just forgotten or something is stillmissing there?
Also, on a related note, I saw there a commit saying that udaddy will
not support the IB port space anymore. Does rpingsupport native IB
for steerable IB UD QPs')

Hi Roland,
This series adds support for Ethernet L2 address resolution for UD QPs, whose
L2 address-handles, unlike RC/UC/XRC/etc QPs are set from user space without
going through uverbs and the kernel IB core.

c. query neigh table in order to know if the neigh has shown up between

6. query vlan id from the interface
This solution depends on libnl v1.
