This is the reply to FEEDBAG_QUERY.

A client will need to handle receiving multiple replies since a Feedbag might not fit in one SNAC, or the server might choose to break it up.

From Aleksandr Shutko: SNAC(13,06) server roster reply SNAC(13,06) FEEDBAG__REPLY


This is the server reply to client roster requests: SNAC(13,04), SNAC(13,05).

Server can split up the roster in several parts. This is indicated with SNAC flags bit 1 as usual, however the "SSI list last change time" only exists in the last packet. And the "Number of items" field indicates the number of items in the current packet, not the entire list.
