They transmit empty packet with wrong value of dbc incremented by 8 at high sampling rate. According to IEC 61883-1, this value should be the same as the one in previous packet. This commit adds a flag named as CIP_EMPTY_HAS_WRONG_DBC. With flag, the value of dbc in empty packet is overwittern by an expected value. This is an example of this quirk: CIP Header 0 CIP Header 1 Payload size 010D0000 9004F759 210 010D0010 90040B59 210 010D0020 90042359 210 01020028 9004FFFF 2 <- 010D0030 90043759 210 010D0040 90044B59 210 010D0050 90046359 210 01020058 9004FFFF 2 <- 010D0060 90047759 210 010D0070 90048B59 210 010D0080 9004A359 210 01020088 9004FFFF 2 <- 010D0090 9004B759 210 010D00A0 9004CB59 210 010D00B0 9004E359 210 010200B8 9004FFFF 2 <- 010D00C0 9004F759 210 010D00D0 90040B59 210 010D00E0 90042359 210 Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai --- Reading git-diff-tree failed
