Fix issue with packet size calculation

Browse Source 
This commit fixes an issue where the transports were calculating an
incorrect size for the packet that was being received. This wasn't
noticable until packet pivot work started, and for some reason wasn't
causing breakages during local testing. Either way, it's fixed now!
