Hi All,

In RoHCv1.2.0 code I find that for compressed packets (UOR-*, UO-*....) the CRC is being computed over the entire 'uncompressed header' rather then following the guidelines provided in section5.9 (of RFC3095) for CRC coverage and computation. RFC3095 mentions that for CRC-3 & CRC-7 the uncompressed header should be divided in 'CRC-Static' and 'CRC-Dynamic' fields and the CRC should be computed. This is not followed in the RoHCv1.2.0 code.

Is the method of CRC Computation is the RoHCv1.2.0 code correct??
