Subject: rsockets: Change the default QP size from 512 to 384
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=32da39f04ff1a232baf630874734637fed38deb4;p=~shefty%2Flibrdmacm.git

rsockets: Change the default QP size from 512 to 384

Simple bandwidth tests using rstream showed no difference in
performance between using a QP sized to 384 entries versus 512.
Reduce the overhead of a default rsocket by using 384 entries.
A user can request a larger size by calling rsetsockopt.
