*
* We assume all nodes are either little-endian or big-endian, and we
* always send messages in the sender's native format. The receiver
* detects the message format by checking the 'magic' field of the message
* (see lustre_msg_swabbed() below).
*
* Each wire type has corresponding 'lustre_swab_xxxtypexxx()' routines
* are implemented in ptlrpc/lustre_swab.c. These 'swabbers' convert the
* type from "other" endian, in-place in the message buffer.
*
* A swabber takes a single pointer argument. The caller must already have
* verified that the length of the message buffer >= sizeof (type).
*
* For variable length types, a second 'lustre_swab_v_xxxtypexxx()' routine
* may be defined that swabs just the variable part, after the caller has
* verified that the message buffer is large enough.
