KTLS implementations currently assume that the start of the in-kernel socket buffer is aligned with the start of a TLS record for the receive side. The socket option to enable KTLS specifies the TLS sequence number of this initial record. When read ahead is enabled, data can be pending in the SSL read buffer after negotiating session keys. This pending data must be examined to ensurs that the kernel's socket buffer does not contain a partial TLS record as well as to determine the correct sequence number of the first TLS record to be processed by the kernel. In preparation for enabling receive kernel offload for TLS 1.3, move the existing logic to handle read ahead from t1_enc.c into ktls.c and invoke it from ktls_configure_crypto().

$FreeBSD$ This directory is for the EXACT same use as src/contrib, except it holds crypto sources. In other words, this holds raw sources obtained from various third party vendors, with FreeBSD patches applied. No compilation is done from this directory, it is all done from the src/secure directory. The separation between src/contrib and src/crypto is the result of an old USA law, which made these sources export controlled, so they had to be kept separate.
