sys/net : if.c
Log message:
let the softnet threads use ifnet refs without accounting for them.
currently you need a real ifnet refcnt via if_get/if_unit, or you
can use if_get_smr in an smr read critical section, but this allows
code in the softnet threads to use an ifnet ref simply by virtue
of running in the softnet thread. this means softnet can avoid the
atomic ops against ifnet refcnts like smr critical sections can
do, but still sleep, which you cant do with in an smr critical
section.
this is implemented by having if_remove net_tq_barriers() before
letting interface teardown proceed.
