Hi Gregory,
This doesn't looks like because of the ixgbe_get_link_capabilities() but
hw->mac.ops.get_media_type.
Crash happens in line 3802, which has:
hw->mac.ops.get_media_type(hw) == ixgbe_media_type_fiber) {
In that stage "speed == 0" but that is expected.
You already aware of the issue and patch, but as reference, this issue
first reported in:
http://dpdk.org/ml/archives/dev/2017-May/065533.html
and proposed fix is in:

Thanks,
