Mod_hdr entries creation is fully synchronized by mod_hdr_tbl->lock. In order to allow concurrent allocation of hardware resources used to offload header rewrite, extend mlx5e_mod_hdr_entry with 'res_ready' completion. Move call to mlx5_modify_header_alloc() out of mod_hdr_tbl->lock critical section. Modify code that attaches new flows to existing mh to wait for 'res_ready' completion before using the entry. Insert mh to mod_hdr table before provisioning it to hardware and modify all users of mod_hdr table to verify that mh was fully initialized by checking completion result for negative value (and to wait for 'res_ready' completion, if necessary).

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.
