section. Move release notes for tunneling-type drivers from network
protocol section to NICs section for consistency (tap(4) release notes
were combined).
first thought and may require serious work to the VOP_RENAME() api itself.
Basically, by the time the VOP_RENAME() function is called, it's already
too late.
it now really gets in the way.
This allows us to fix several problems- not least of which was problems
of ordering about when you'd have a device softc for an miibus child
available or not. Move some steps of things around.
Put the ifnet/arpcom structure at the head of the softc (PR 29249).
Don't do tx gc in the interrupt service routine- that seems to make
things a bit more efficient.
Enable jumbo support by default- but this version of 'jumbo' is broken
because it really is just using multiple tfd/rfd's to match a packet,
which will never be > CLSIZE anyway.
This should begin the first steps toward cleaning this driver up.

As I sing to CVS:
Have I told you lately that I hate your guts? Have I told you
all SCM's are above you? You fill my heart with pain, take away
all my merging joy, grow my troubles that's what you do."
with an ifnet structure (so device_get_softc will get one).
If memory allocation fails in mii_phy_probe, don't just march ahead into
a panic- return ENOMEM.

will be one for struct proc in stable. those drivers needing to have
cross version portability should use d_thread_t instead of inventing
their own means. Non-drivers, and drivers that either only run on
-current or must look under the covers of the struct proc/thread
should must not use this.
As noted in arch@, this minorly violates style(9), but the sys/conf.h
devsw already violates this and all I'm doing is extending the
violation to ease the burdon on device driver writers. It was judged
that this minor violation, which doesn't impact userland or those
people not using it, was preferable to the alternatives (eg #define
proc thread). C does not allow a way to rename or alias structs
easily, so we fall back to using a typedef.
Bump FreeBSD_version to reflect this change (porters guide to be done
in a separate commit).
in vfs_syscalls.c:
if (mp->mnt_stat.f_owner != p->p_ucred->cr_uid &&
(error = suser_td(td)) != 0) {
unwrap_lots_of_stuff();
return (error);
}
to:
if (mp->mnt_stat.f_owner != p->p_ucred->cr_uid) {
error = suser_td(td);
if (error) {
unwrap_lots_of_stuff();
return (error);
}
}
This makes the code more readable when complex clauses are in use,
and minimizes conflicts for large outstanding patchsets modifying the
kernel authorization code (of which I have several), especially where
existing authorization and context code are combined in the same if()
conditional.
