CVS commit: src/sys/net

[David Young <dyoung%netbsd.org@localhost>]

Module Name:    src
Committed By:   dyoung
Date:           Thu Aug 13 00:23:32 UTC 2009

Modified Files:
        src/sys/net: if.c if.h

Log Message:
Use sysctl(9) to expose to userland each interface transmission
queue's maximum length, current length, and number of drops.  E.g.,

% sysctl net.interfaces.bnx0
net.interfaces.bnx0.sndq.len = 0
net.interfaces.bnx0.sndq.maxlen = 509
net.interfaces.bnx0.sndq.drops = 0

Let userland adjust the maximum queue length.

While I'm here, add a 64-bit generation number, if_index_gen, to
ifnet; the pair [ifp->if_index, ifp->if_index_gen] can serve to
identify an ifnet for the lifetime of the system.  I will use this
in an upcoming change.

Ok matt@.
