Encap entries creation is fully synchronized by encap_tbl_lock. In order to
allow concurrent allocation of hardware resources used to offload
encapsulation, extend mlx5e_encap_entry with 'res_ready' completion. Move
call to mlx5e_tc_tun_create_header_ipv{4|6}() out of encap_tbl_lock
critical section. Modify code that attaches new flows to existing encap to
wait for 'res_ready' completion before using the entry. Insert encap entry
to table before provisioning it to hardware and modify all users of the
encap table to verify that encap was fully initialized by checking
completion result for non-zero 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.
