[PATCH net-next 3/3] net: ipa: extend the INDICATION_REGISTER request

Alex Elder
2021-03-15T15:22:10Z

The specified format of the INDICATION_REGISTER QMI request message
has been extended to support two more optional fields:
endpoint_desc_ind:
sender wishes to receive endpoint descriptor information via
an IPA ENDP_DESC indication QMI message
bw_change_ind:
sender wishes to receive bandwidth change information via
an IPA BW_CHANGE indication QMI message

Add definitions that permit these fields to be formatted and parsed
by the QMI library code.
