The patch does not work with old FW.
The old fw set the bit; however, it has bug on FRWR

A drop of the FW with a fix is already available and it will be GA in
few months
I don't fully understand - do you mean the need for setting the
LOCAL_WRITE bit goes away with this upcoming ConnectX firmware?
No - the setting for LOCAL_WRITE bit will still be needed for this
upcoming ConnectX FW.
Ok, two question in that case...
1) What's the firmware fix that Tziporet mentions actually for?
A FW bug on Fast registration WR operation
2) Is the need for LOCAL_WRITE documented at the FRMR verb layer,
and do other implementations agree that it's harmless?
It is documented in ConnectX's PRM (Program Reference Manual)
Jon already verify the patch and it's harmless to Chelsio.

Tom.
In other words, the NFS/RDMA is correct, currently, and Vu's patch
is therefore purely a workaround for a firmware bug?
I feel differently about pushing this fix upstream, if so.
Tom.
