Define the fields for the ENDP_INIT_CTRL, ENDP_INIT_CFG, ENDP_INIT_NAT, ENDP_INIT_HDR, and ENDP_INIT_HDR_EXT IPA registers for all supported IPA versions. Create enumerated types to identify fields for these IPA registers. Use IPA_REG_STRIDE_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Move ipa_header_size_encoded() and ipa_metadata_offset_encoded() out of "ipa_reg.h" and into "ipa_endpoint.c". Change them so they take an additional ipa_reg structure argument, and use ipa_reg_encode() to encode the parts of the header size and offset prior to writing to the register. Change their names to be verbs rather than nouns. Use ipa_reg_encode(), ipa_reg_bit, and ipa_reg_field_max() to manipulate values to be written to these registers, remove the definition of the no-longer-used *_FMASK symbols.

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.
