[DragonFlyBSD - Bug #2565] "ifconfig ix0 up" panic

[lt pig via Redmine <bugtracker-admin@xxxxxxxxxxxxxxxxxxxxx>]

Issue #2565 has been updated by ltpig402a.


- This is a 82599EB, using 10Gbase-Twinax.
- HW platform is a Intel DZ77BH-55K, i5-3570K CPU, 32GB Ram, running Dfly 64bit 3.4.1 
- Generic kernel (with IPv6) was used with the panic.

The reason for the "..." is that the screen was captured with a phone and re-typed, as follows -

Bug #2565: "ifconfig ix0 up" panic

Just installed a new nic - 10G 82599 dual port. 

The system recognizes the ixgbe device and shows up ix0 and ix1. 

Whenever a "ifconfig ix0 up" or "ifconfig ix1 up" is issued, the system crashed -
