8.1 SPLIP mode does not work with some header sizes

The Secure Protocol Layers Improved Performances (SPLIP) mode does not work when the ESP header is not an integer multiple of 4 words.

Work Around

When the ESP header is not an integer multiple of 4 words, disable SPLIP mode to stop AES from automatically uploading the encrypted payload into SHA, and use the central DMA to feed SHA with the encrypted payload.
