  "message": "net: ipa: program metadata mask differently\n\nThe way the mask value is programmed for QMAP RX endpoints was based\non some wrong assumptions about the way metadata containing the QMAP\nmux_id value is formatted.  The metadata value supplied by the\nmodem is *not* in QMAP format, and in fact contains the mux_id we\nwant in its (big endian) low-order byte.  That byte must be written\nby the IPA into offset 1 of the QMAP header it inserts before the\nreceived packet.\n\nQMAP TX endpoints *do* use a QMAP header as the metadata sent with\neach packet.  The modem assumes this, and based on that assumes the\nmux_id is in the second byte.  To match those assumptions we must\nprogram the modem TX (QMAP) endpoint HDR register to indicate the\nmetadata will be found at offset 0 in the message header.\n\nThe previous configuration managed to work, but it was not working\ncorrectly.  This patch fixes a bug whose symptom was receipt of\nmessages containing the wrong QMAP mux_id.\n\nIn fixing this, get rid of ipa_rmnet_mux_id_metadata_mask(), which\nwas more or less defined so there was a separate place to explain\nwhat was happening as we generated the mask value.  Instead, put a\nlonger description of how this works above ipa_endpoint_init_hdr(),\nand define the metadata mask to use as a simple constant.\n\nSigned-off-by: Alex Elder \u003celder@linaro.org\u003e\nSigned-off-by: David S.
