Restore if_cp.c 1.27
----------------------------
revision 1.27
date: 2005/09/19 03:10:16; author: imp; state: Exp; lines: +3 -2
Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash. Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.
In fact, this change do nothing for this driver. It is protected from
this by cp_destroy variable. This variable also protects driver from initiation
of any activity from network stack with disabled intr handler with this change
applied.
