    dccp: Add packet type information to CCID-specific option parsing · 4874c131

    This
     1. adds packet type information to ccid_hc_{rx,tx}_parse_options(). This is
        necessary, since table 3 in RFC 4340, 5.8 leaves it to the CCIDs to state
        which options may (not) appear on what packet type.
    
     2. adds such a check for CCID-3's {Loss Event, Receive} Rate as specified in
        RFC 4340 8.3 ("Receive Rate options MUST NOT be sent on DCCP-Data packets")
        and 8.5 ("Loss Event Rate options MUST NOT be sent on DCCP-Data packets").
    
     3. removes an unused argument `idx' from ccid_hc_{rx,tx}_parse_options(). This
        is also no longer necessary, since the CCID-specific option-parsing routines
        are passed every single parameter of the type-length-value option encoding.
