[openib-general] Want to learn more about the FMR

[Ian Jiang]

It is said in "Zero Copy Sockets Direct Protocol over InfiniBand -
Preliminary Implementation and Performance Analysis" that the FMR  is a
Mellanox feature extending the 1.1 InfiniBand specification, and a similar
feature was added later on to the 1.2 InfiniBand specification. But I have
got nothing about the FMR in "InfiniBand™ Architecture Specification Release
1.2" (http://www.infinibandta.org/specs/register/publicspec/).
I read the description of FMR related verbs in "Mellanox IB-Verbs API (VAPI)
1.00, however I  am not very clear of the  difference between FMR
registering and common registering. Is there a description of more details?
Any suggestion is appreciated!
