(In reply to Daniel Ponte from comment #4)
Can you show me the output of
  print ((struct ifnet *)0xfffff8004c742000)->if_afdata[28]
  print *(struct ifnet *)0xfffff8004c742000 
on kgdb?

Probably %rdi still held the ifnet pointer at the fatal fault because
if_getafdata() was a tiny function  
(I can confirm if the disassemble output of if_getafdata is provided).
