rin | sys: Drop redundant NULL check before m_freem(9)
m_freem(9) safely has accepted NULL argument at least since 4.2BSD:
https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/src/sys/sys/uipc_mbuf.c
Compile-tested on amd64/ALL.

riastradh | if_stats(9): Add ifp argument to if_stat..._ref.
This will enable us to pass the ifp through to a dtrace probe inside.
No functional change intended in this change, but this is an API
change visible to modules so it shouldn't be pulled up.

riastradh | vmxnet(4): Fix various MP bugs.
- Defer reset to workqueue.
=> vmxnet3_stop_locked is forbidden in softint.
=> XXX Problem: We still take the core lock in softint, and we
still take the core lock around vmxnet3_stop_locked. TBD.
- Touch if_flags only under IFNET_LOCK.
=> Cache ifp->if_flags & IFF_PROMISC in vmxnet3_ifflags_cb.
=> Don't call vmxnet3_set_rxfilter unless up and running; cache
this as vmx_mcastactive. Use ENETRESET in vmxnet3_ifflags_cb
instead of calling vmxnet3_set_rxfilter directly.
. (The cache is currently serialized by the core lock, but it
might reasonably be serialized by an independent lock like in
usbnet(9).)
- Fix vmxnet3_stop_rendezvous so it actually does something.
=> New vxtxq_stopping, vxrxq_stopping variables synchronize with
Rx/Tx interrupt handlers.
- Sprinkle IFNET_LOCK and core lock assertions.

It is correct to update ifp statistics per packet, just remove commented out old statistics code.
The code is commented out by if_vmx.c:r1.57.

msaitoh | Call txeof first, then rxeof for the consistency.
There are three functions where the txeof and rxeof are called. The MSI-X
interrupt function and the workqueue function call rxeof first, then rxeof.
For legacy interrupt. rxeof is called first. Modify it to match with other
two.

riastradh | vmx(4): Omit needless membar_sync wrapper.
Nothing uses this, and it is unlikely that any part of this driver
will need store-before-load ordering to synchronize with the host.

knakahara | Fix vmx(4) receive workqueue problem on qemu, reported by ozaki-r@n.o, thanks.
ESXi stops interrupt by vmxnet3_disable_intr() immediately. In contrast, qemu
does not stop interrupt soon. Hmm, qemu's behavior seems not to be correct,
however, there is no explicit specification of vmxnet3. So, we have to accept
that behavior.
