This commit introduces direct data placement offload to NVME
TCP. There is a context per queue, which is established after the
handshake
using the tcp_ddp_sk_add/del NDOs.
Additionally, a resynchronization routine is used to assist
hardware recovery from TCP OOO, and continue the offload.

This commit introduces support for CRC offload to direct data placement

Hi Marcel,
This patch further improves suspend handling by getting rid of the
separate function used for always configuring LE scan. Instead, we only
configure LE scan if it is necessary and properly set the task bits
depending on what actions were taken.
The previously sent-up CL was incomplet
Add a missing SUSPEND_SCAN_ENABLE in passive scan, remove the separate
function for configuring le scan during suspend and update the request
complete function to clear both enable and disable tasks.
