Subject: ofed-mic add check for existing ibpd to start function
X-Git-Tag: vofed-3.12-1-rc1~1
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=6071f10c7e3d375fadab527005a682b0e0e3ff43;p=~emulex%2Ffor-vlad%2Fold%2Fcompat-rdma.git

ofed-mic add check for existing ibpd to start function

Add a check for an existing ibpd daemon before starting another.
This prevents multiple "service ofed-mic start" commands from
launching multiple copies of the ibpd daemon, spawning more
driver worker threads than intended.
