Bug ID: 215101
Summary: [ixgbe] Intel X552 SFP+ fails to initialize when no
SFP module is plugged in
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Many People
Priority: ---

Fix
Due to the insufficient error handling Intel X552 SFP+ (8086:15ac)
will fail to initialize on boot when no modules are plugged in and
become completely unusable afterwards.
I have discovered this bug on OpenBSD when updating our driver so
there's a chance that this is not an issue on FreeBSD (I haven't
tested), so you may consider this just a heads up.
I'm attaching the fix that makes it operational on OpenBSD. This
chunk is based on the similar one for 82599. Setting PHY type to
"ixgbe_phy_none" will come in handy during "ifconfig up" since
ixgbe_init[_locked] will re-do the PHY/SFP initialization if the
PHY type has been previously set to "none".
Cheers,
Mike
