which is a more generic "that's not in the tree" response.
ENOPROTOOPT was specific to the net subtree under the old framework,
and didn't add much value (other than letting the caller know they
were looking up something under the net subtree, which they presumably
ought to have known already).
Do a little mbuf rework while here. Change all uses of MGET*(*, M_WAIT, *)
to m_get*(M_WAIT, *). These are not performance critical and making them
call m_get saves considerable space. Add m_clget analogue of MCLGET and
make corresponding change for M_WAIT uses.
Modify netinet, gem, fxp, tulip, nfs to support MBUFTRACE.
Begin to change netstat to use sysctl.
fix PR7059 (partial): mbuf cluster counts were based on counters which
are no longer maintained.
(full fix will involve renaming the now-unused fields in mclstat in mbuf.h)
Add code to netstat to use libkvm to for kernel variables "mclbytes"
and "msize', and if found, use those for netstat -m rather than
compiled-in defaults.
of long-standing bugs:
- Actually deal with the fact that the kernel ifnet list is
a TAILQ; it just happened to work before.
- Use kvm_openfiles() instead of kvm_open(). The code passed
arguments to kvm_open() as if it were kvm_openfiles(), but
apparently went unnoticed since the prototypes are the same.
Amusing bit: there were XXX's in the code which seemed to
apologize for a verbose libkvm, when it happened to be a
bug in netstat!
