You are right, the driver should not parse the event a second time.

What I would like to keep is limiting the mask to the controllers that
set these bits, as hci_bcm4377 already does with
HCI_QUIRK_FIXUP_LE_EXT_ADV_REPORT_PHY:

- add HCI_QUIRK_FIXUP_LE_ADV_REPORT_TYPE
- set it in hci_bcm on Apple machines and in hci_bcm4377
- test the quirk in hci_le_adv_report_evt() instead of the
  manufacturer, keeping the mask from 88397423671f

That drops patch 2 and replaces the revert in patch 3. Would that work
for you? Then I would send a v2 along these lines, with patch 1 and 4
unchanged.

Thanks,
Andre
