- * We need a way for the decompressor to influence the generation of CCP
- * Reset-Requests in a variety of ways. The decompressor is already returning
- * a lot of information (generated skb length, error conditions) so we use
- * another parameter. This parameter is a pointer to a structure which is
- * to be marked valid by the decompressor and only in this case is ever used.
- * Furthermore, the only case where this data is used is when the decom-
- * pressor returns DECOMP_ERROR.
- *
- * We use this same struct for the reset entry of the compressor to commu-
- * nicate to its caller how to deal with sending of a Reset Ack. In this
- * case, expra is not used, but other options still apply (suppressing
- * sending with rsend, appending arbitrary data, etc).
