Mechanically convert to if_inc_counter().
Remove disabled code, that is very unlikely to be ever enabled again,
as well as the comment that explains why is it disabled.
Increase errors, not queue drops, in cases the module is supplied
with a bad packet or if mbuf allocation failes.
Fix cdev.  It is a device node name, not a pathname.
Merge branch 'hardened/current/log' into hardened/current/master
This is a white-space/comment cleanup commit as a precursor for
some upcoming work on the NTP kernel PLL.
Remove ifq_drops from struct ifqueue. Now queue drops are accounted in
struct ifnet if_oqdrops.

Some netgraph modules used ifqueue w/o ifnet. Accounting of queue drops
is simply removed from them. There were no API to read this statistic.
