VT6122 gigabit ethernet chip and integrated 10/100/1000 copper PHY.
The vge driver has been added to GENERIC for i386, pc98 and amd64,
but not to sparc or ia64 since I don't have the ability to test
it there. The vge(4) driver supports VLANs, checksum offload and
jumbo frames.
Also added the lge(4) and nge(4) drivers to GENERIC for i386 and
pc98 since I was in the neighborhood. There's no reason to leave them
out anymore.
It can be switched back once 5.3 is tested and released. Also turn on
PREEMPTION as many of the stability problems with it have been fixed.
MT5: 3 days.
compile option. All FreeBSD packet filters now use the PFIL_HOOKS API and
thus it becomes a standard part of the network stack.
If no hooks are connected the entire packet filter hooks section and related
activities are jumped over. This removes any performance impact if no hooks
are active.
Both OpenBSD and DragonFlyBSD have integrated PFIL_HOOKS permanently as well.
with the COMPAT_LINUX32 option. This is largely based on the i386 MD Linux
emulations bits, but also builds on the 32-bit FreeBSD and generic IA-32
binary emulation work.
Some of this is still a little rough around the edges, and will need to be
revisited before 32-bit and 64-bit Linux emulation support can coexist in
the same kernel.
their own directory and module, leaving the MD parts in the MD
area (the MD parts _are_ part of the modules). /dev/mem and /dev/io
are now loadable modules, thus taking us one step further towards
a kernel created entirely out of modules. Of course, there is nothing
preventing the kernel from having these statically compiled.
NO_ADAPTIVE_MUTEXES. This option has been enabled by default on amd64 for
quite some time, and has been extensively tested on i386 and sparc64. It
shows measurable performance gains in many circumstances, and few negative
effects. It would be nice in t he future if adaptive mutexes actually went
to sleep after a certain amount of spinning, but that will require quite a
bit more testing.
known samples of broken chipsets that needed mixed mode in the first place
are so broken (ie: locks up) that we can't use IO APIC mode at all and it
needs to be turned off in the bios. So, the MIXED_MODE penalty on the
good chipsets gained nothing.

- turn on SMP in generic
- add 'device atpic' - this is unconditional on i386, but certain nvidia
based systems need to disable acpi because the reference bios seems to be
hosed. If acpi is disabled, we won't find the apic. amd64 has the
mptable code in a seperate compile option as well.
- turn sym back on, it doesn't fail to compile anymore.
