[PATCH v4 net-next 2/2] tcp: Add Redundant Data Bundling (RDB)

RDB is a mechanism that enables a TCP sender to bundle redundant (already sent) data with TCP packets containing new data. By bundling (retransmitting) already sent data with each TCP packet containing new data, the connection will be more resistant to sporadic packet loss which reduces the

Looking at how callers use this, maybe we should just rename init_used to vhost_vq_init_access. The _used suffix was a hint that we access the vq used ring. But maybe what callers care about is that it must be called after access_ok. Also, this function manipulates the vq->is_le field which isn't
