Even working in round-robin mode ppp avoids packet reordering as it may
lead to problems with compression/encryption protocols. Multilink header
includes serial number especially for this purpose.

Mpd supports both. There were some mistakes in multilink transmission
part of ng_ppp kernel module working in splitting mode that in some
cases could lead to ineffective packet distribution, but they were fixed
8 months ago at 6-STABLE.
