CONFIG_INFINIBAND_IPOIB_DEBUG also enables the "ipoib_debugfs"

CONFIG_INFINIBAND_IPOIB_DEBUG also enables files in the debugfs

virtual filesystem. By mounting this filesystem, for example with

mkdir -p /ipoib_debugfs

mount -t ipoib_debugfs none /ipoib_debufs
|

mount -t debugfs none /sys/kernel/debug

it is possible to get statistics about multicast groups from the

files /sys/kernel/debug/ipoib/ib0_mcg and so on.

The performance impact of this option is negligible, so it
|

is safe to enable this option with debug_level set to 0 for normal
