H A D | talitos.c | diff f3c85bc1bc72b4cc8d58664a490a9d42bdb6565a Wed Jul 30 10:26:57 CEST 2008 Lee Nipper <lee.nipper@freescale.com> crypto: talitos - Add handling for SEC 3.x treatment of link table
Later SEC revision requires the link table (used for scatter/gather) to have an extra entry to account for the total length in descriptor [4], which contains cipher Input and ICV. This only applies to decrypt, not encrypt. Without this change, on 837x, a gather return/length error results when a decryption uses a link table to gather the fragments. This is observed by doing a ping with size of 1447 or larger with AES, or a ping with size 1455 or larger with 3des.
So, add check for SEC compatible "fsl,3.0" for using extra link table entry.
