Subject: [PATCH net-next v3 0/6] net: qualcomm: rmnet: stop using C bit-fields

Version 3 of this series uses BIT() rather than GENMASK() to define
single-bit masks.  It then uses a simple AND (&) operation rather
than (e.g.) u8_get_bits() to access such flags.  This was suggested
by David Laight and really prefer the result.  With Bjorn's
permission I have preserved his Reviewed-by tags on the first five
patches.

Version 2 fixed bugs in the way the value written into the header
was computed.

The series was first posted here:
  https://lore.kernel.org/netdev/20210304223431.15045-1-elder@linaro.org/
Below is a summary of the original description.

This series converts data structures defined in <linux/if_rmnet.h>
so they use integral field values with bitfield masks rather than
relying on C bit-fields.
  - The first three patches lay the ground work for the others.
      - The first adds endianness notation to a structure.
      - The second simplifies a bit of complicated code.
      - The third open-codes some macros that needlessly
        obscured some simple code.
  - Each of the last three patches converts one of the structures
    defined in <linux/if_rmnet.h> so it no longer uses C bit-fields.
