SVN rev 191417 on 2009-04-23 10:59:40Z by rwatson
Move portions of data structure initialization from if_attach() to
if_alloc(), and portions of data structure destruction from if_detach()
to if_free(). These changes leave more of the struct ifnet in a
safe-to-access condition between alloc and attach, and between detach
and free, and focus on attach/detach as stack usage events rather than
data structure initialization.
Affected fields include the linkstate task queue, if_afdata lock,
address lists, kqueue state, and MAC labels. ifq_attach() ifq_detach()
are not moved as ifq_attach() may use a queue length set by the device
driver between if_alloc() and if_attach().
