A minor note- it would help to add some comments here explaining 
that the pong has already been added to the sendq earlier.. 
in the case of IB, if RDS_LL_SEND_FULL has been set, it takes some
head-scratching to figure out how the pong gets sent, and a  few
comments could help clarify that.

but other than that, the contents look good to me, thus
