The values of 'sequence' and 'secret' are arbitrary byte strings which might
contain IAC (0xff) or SE (0xf0) in any position. Lack of escaping during
transmission might cause receiver confusion and potentially vMotion failures.
This change adds escaping of these 'sequence' and 'secret' values before
transmission. They are already being unescaped correctly during receipt; Only
the transmit side needs to be fixed.
