OK, I will name the file "include/linux/if_rmnet.h" as you suggest.
It will still only define the three structures that I need in the
IPA driver; I won't expose anything else from the rmnet_data driver.
I will mention now that, to facilitate addressing Arnd's concerns
about the portability of using C bit-fields in these structures,
I made a set of other changes (including a bug fix in one of
the structure definitions). As a preview, here are the subject
lines for that series:
net: qualcomm: rmnet: fix struct rmnet_map_header
net: qualcomm: rmnet: kill RMNET_MAP_GET_*() accessor macros
net: qualcomm: rmnet: use field masks instead of C bit-fields
net: qualcomm: rmnet: don't use C bit-fields in rmnet checksum header
net: qualcomm: rmnet: don't use C bit-fields in rmnet checksum trailer
soc: qcom: ipa: get rid of a variable in rmnet_map_ipv4_ul_csum_header()
net: create "include/linux/if_rmnet.h"
I will be posting that as a separate series now and will have
the IPA driver series mention a dependence on that.
