/**

 *  struct ccid_operations  -  Interface to Congestion-Control Infrastructure

 *

 *  @ccid_id: numerical CCID ID (up to %CCID_MAX, cf. table 5 in RFC 4340, 10.)

 *  @ccid_name: alphabetical identifier string for @ccid_id

 *  @ccid_owner: module which implements/owns this CCID

 *  @ccid_hc_{r,t}x_slab: memory pool for the receiver/sender half-connection

 *  @ccid_hc_{r,t}x_obj_size: size of the receiver/sender half-connection socket

 *

 *  @ccid_hc_{r,t}x_init: CCID-specific initialisation routine (before startup)

 *  @ccid_hc_{r,t}x_exit: CCID-specific cleanup routine (before destruction)

 *  @ccid_hc_rx_packet_recv: implements the HC-receiver side

 *  @ccid_hc_{r,t}x_parse_options: parsing routine for CCID/HC-specific options

 *  @ccid_hc_{r,t}x_insert_options: insert routine for CCID/HC-specific options

 *  @ccid_hc_tx_packet_recv: implements feedback processing for the HC-sender

 *  @ccid_hc_tx_send_packet: implements the sending part of the HC-sender

 *  @ccid_hc_tx_packet_sent: does accounting for packets in flight by HC-sender

 *  @ccid_hc_{r,t}x_get_info: INET_DIAG information for HC-receiver/sender

 *  @ccid_hc_{r,t}x_getsockopt: socket options specific to HC-receiver/sender
