Add tx_sop_type to tcpm_pd_send_control and rx_sop_type to tcpm_pd_ctrl_request. TCPC_TX_SOP is added to all pd_send_control calls, but TCPC_TX_SOP_PRIME is added to pd_send_control for a SOFT_RESET message sent after a Vconn swap that makes the Port the Vconn source. Likewise, tcpm_pd_ctrl_request resets the proper protocol layer depending on rx_sop_type for SOFT_RESET. VCONN_SWAP_TURN_ON_VCONN now moves to a new state, VCONN_SWAP_SEND_SOFT_RESET. This state sends SOFT_RESET over SOP' before transitioning to the ready state if applicable. It transitions after PD_T_VCONN_STABLE, definied in pd.h as the time required for Vconn to be on before transmitting messages.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
