Currently ECPF enables external host PF too early in the initialization sequence for Ethernet links when ECPF is eswitch manager. Due to this, when external host PF driver is loaded, host PF's HCA CAP has inner_ip_version supported by NIC RX flow table. This capability is later updated by firmware after ECPF driver enables ENCAP/DECAP as eswitch manager. This results into a timing race condition, where CREATE_TIR command fails with a below syndrome on host PF. mlx5_cmd_check:775:(pid 510): CREATE_TIR(0x900) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x562b00) Hence, enable the external host PF after necessary eswitch and per vport initialization is completed. Continue to enable host PF when eswitch manager capability is off for a ECPF.

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.
