History
Ryan Stone ab607f28e3 Don't read if_counters with if_addr_lock held 
Calling into an ifnet implementation with the if_addr_lock already
held can cause a LOR and potentially a deadlock, as ifnet
implementations typically can take the if_addr_lock after their
own locks during configuration.  Refactor a sysctl handler that
was violating this to read if_counter data in a temporary buffer
before the if_addr_lock is taken, and then copying the data
in its final location later, when the if_addr_lock is held.
