Lines Matching full:coverage

37   IPPROTO need to be changed; senders additionally set the checksum coverage
58   using partial checksum coverage and so emulate UDP mode (full coverage).
60   To make use of the partial checksum coverage facilities requires setting a
61   single socket option, which takes an integer specifying the coverage length:
63     * Sender checksum coverage: UDPLITE_SEND_CSCOV
70       sets the checksum coverage length to 20 bytes (12b data + 8b header).
76     * Receiver checksum coverage: UDPLITE_RECV_CSCOV
79       required to enable traffic with partial checksum coverage. Its function is
81       all packets which have a coverage _less_ than this value. For example, if
83       packets with a minimum coverage of 20 are admitted::
92   A detailed discussion of UDP-Lite checksum coverage options is in section IV.
123   If the sender specifies a value of 0 as coverage length, the module
124   assumes full coverage, transmits a packet with coverage length of 0
125   and according checksum.  If the sender specifies a coverage < 8 and
127   if the specified coverage length exceeds the packet length, the packet
128   length is used instead as coverage length.
132   The receiver specifies the minimum value of the coverage length it

176   The send buffer size has implications on the checksum coverage length.

187   The coverage packet covers the UDP-Lite header and 848 bytes of the
189   that for the second packet, the coverage length exceeds the packet
190   length. The kernel always re-adjusts the coverage length to the packet
