Use gettime() instead of assignment from `time'. (`time' is too 

volatile to use outside of splclock().  microtime() is probably too
expensive to use for every i/o.  However, setting ifi_lastchange for
every i/o is just wrong according to the comment about ifi_lastchange
in <net/if.h>.  It is set then for atm, fddi and the latest version
of ppp.)
