Subject: Don't set last byte of GID for non-global address vectors
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=3e19c50ee192dfa998007fc12fab997fc75ff252;p=~shefty%2Flibmlx4.git

Don't set last byte of GID for non-global address vectors

Previous generation HCAs needed the last byte of the GID set to 2 for
non-global address vectors, but ConnectX just ignores the remote GID
field for non-global AVs, so remove the unnecessary code that sets it.
