Was discussing with Xialong, it is in the gray area that if this is a fix
or new feature.
It is not the case that initial implementation says that multi segment
mbufs are supported, in that case this is not a fix but enabling multi
segment support.
So perhaps better to update commit log in this way to prevent confusion
for the fixing and fix tag..
