Summary:                    Casting alignment problem in send_client causes bad
seq to be generated on ARM platform
Description: 
In send_client(), a char array is cast as a short array.  If the char array
starts on an odd byte, the short array cast will not be aligned properly
and setting the seq into the array will not be the expected result.

This happens on the ARM platform.
