a048affba5 Add m_sanity(struct mbuf *m, int sanitize) to do some heavy sanity
checking on mbuf's and mbuf chains.  Set sanitize to 1 to garble
illegal things and have them blow up later when used/accessed.

m_sanity()'s main purpose is for KASSERT()'s and debugging of non-
kosher mbuf manipulation (of which we have a number of).

ed111688e9 Add m_demote(struct mbuf *m, int all) to clean up mbuf (chain) from
any tags and packet headers.  If "all" is set then the first mbuf
in the chain will be cleaned too.

This function is used before an mbuf, that arrived as packet with
m->flags & M_PKTHDR, is appended to an mbuf chain using m->m_next
(not m->m_nextpkt).

08daf78765 Eliminate bogus seatbelt in wi_cmd. This may have been appropriate
for the spl-era locking, but now that we can have multiple, concurrent
interrupts for multiple wi devices, having a global check to make sure
at most one of them was in wi_cmd no longer makes sense.

00d12766ef - Allow for VLAN-sized frames and set IFCAP_VLAN_MTU.
- On resume all registers have to be initialized again like after
  power-on so reset sc_inited in gem_suspend() in order get all of
  the registers set next time gem_init_regs() is called.
- On at least some ERI and GEM revisions GEM_MAC_RX_OVERFLOW happen
  often due to a silicon bug and re-initializing is all we can do
  about these errors so make handling them non-verbose.
- Remove a superfluous memset(3) call in gem_meminit(), all elements
  are initialized to 0 anyway.

Joseph Koshy
7ef5ed2bb1 - Special-case NMI handling on the AMD64.
On entry or exit from the kernel the 'alltraps' and 'doreti' code
  used taken by normal traps disables interrupts to protect the
  critical sections where it is setting up %gs.

  This protection is insufficient in the presence of NMIs since NMIs
  can be taken even when the processor has disabled normal interrupts.
  Thus the NMI handler needs to actually read MSR_GBASE on entry to
  the kernel to determine whether a swap of %gs using 'swapgs' is
  needed.  However, reads of MSRs are expensive and integrating this
  check into the 'alltraps'/'doreti' path would penalize normal
  interrupts.

- Teach DDB about the 'nmi_calltrap' symbol.

68e84b98b2 Fix a panic in softclock() if the interface is destroyed with a bpf consumer
attached.

This is caused by bpf_detachd clearing IFF_PROMISC on the interface which does
a SIOCSIFFLAGS ioctl. The problem here is that while the interface has been
stopped, IFF_UP has not been cleared so IFF_UP != IFF_DRV_RUNNING, this causes
the ioctl function to init() the interface which resets the callouts.

The destroy then completes and frees the softc but softclock will panic on a
dead callout pointer.

Ensure ifp->if_flags matches reality by clearing IFF_UP when we destroy.
