[openfabrics-ewg] ib_sdp module is reloading itself

[Scott Weitzenkamp (sweitzen)]

OFED adds this line to modprobe.conf to autoload ib_sdp when SDP is
used, much like how ib_ipoib is autoloaded when IPoIB is used.
 
# grep sdp /etc/modprobe.conf
alias net-pf-27 ib_sdp

	Hi:
	 
	While testing SDP, I observed that sdp module is getting loaded
by itself. I tried following steps:
	 
	1. modprobe ib_sdp
	2. export LD_PRELOAD=/usr/local/ofed/lib/libsdp.so
	3. export LIBSDP_CONFIG_FILE=/usr/local/ofed/etc/libsdp.conf
netperf
	4. modprobe -r ib_sdp or rmmod ib_sdp.
	5. netserver
	 
	Please note that I didn't change any environment variables.
After executing netserver, when i did lsmod, I observed sdp module. Let
me know if this is expected behaviour.
	 
	Attached below are the logs.
	 
	Thanks
	Karun
