This is fine but the problem lies when add_buf fails, it called notify and the host sends all the pending tx pkts. When enable_cb was...

This patch-set introduces the CAIF Virtio Link layer. The purpose is to communicate with a remote processor (a modem) over shared memory. Virtio is used as the transport mechanism, and the Remoteproc framework provides configuration and management of the Virtio rings and devices. The modem and Linux host may be on the same SoC, or connected over a shared memory interface such as LLI. Zero-Copy
