Subject: [PATCH] [efi] perform cable detection at NII initialization on HPE
|
||||
557SFP+
|
||||
|
||||
Commit c0b61bad99ba ("[efi] Work around bugs in Emulex NII driver",
|
||||
2015-08-17) added PXE_OPFLAGS_INITIALIZE_DETECT_CABLE to nii_open() for
|
||||
working around Emulex NII driver bugs.
|
||||
|
||||
That broke some Mellanox drivers, so commit 6324227dcaa8 ("[efi] Skip
|
||||
cable detection at initialisation where possible", 2017-03-19) predicated
|
||||
PXE_OPFLAGS_INITIALIZE_DETECT_CABLE on the NII driver's *inability* to
|
||||
report link status.
|
||||
|
||||
This in turn breaks the NII driver on (some?) HPE 557SFP+ cards, as those
|
||||
drivers are capable of reporting link status, but they still need cable
|
||||
detection.
|
||||
|
||||
So check for this card (through PCI vendor / device / subsys vendor /
|
||||
subsys device identifiers), and opt for cable detection regardless of link
|
||||
status reporting.
