Description

When I try to mount lustre with GSS (SSK) enabled I receive checksum errors using a multi-rail client where I do not when using only a single interface.  My guess is the NID is encoded in the checksum though I haven't dug into the cause yet.  I also had lots of errors when using GSS on multi-rail servers although the errors were different.
