cause the EC to stop handling future events because the GPE stayed masked.
Set a flag when queueing a GPE handler since it will ultimately re-enable
the GPE. In all other cases, re-enable it ourselves. I reworked the
patch from the submitter.

structures. Detect when ifnet instances are detached from the network
stack and perform appropriate cleanup to prevent memory leaks.
This has been implemented in such a way as to be backwards ABI compatible.
Kernel consumers are changed to use if_delmulti_ifma(); in_delmulti()
is unable to detect interface removal by design, as it performs searches
on structures which are removed with the interface.
With this architectural change, the panics FreeBSD users have experienced
with carp and pfsync should be resolved.

Main points of this change:
* Drop frames immediately if the interface is not marked IFF_UP.
* Always trim off the frame checksum if present.
* Always use M_VLANTAG in preference to passing 802.1Q frames
to consumers.
* Use __func__ consistently for KASSERT().
* Use the M_PROMISC flag to detect situations where ether_input()
may reenter itself on the same call graph with the same mbuf which
was promiscuously received on behalf of subsystems such as
netgraph, carp, and vlan.
* 802.1P frames (that is, VLAN frames with an ID of 0) will now be
passed to layer 3 input paths.
* Deal with the special case for CARP in a sane way.
This is a significant rewrite of code on the critical path. Please report
any issues to me if they arise. Frames will now only pass through dummynet
if M_PROMISC is cleared, to avoid problems with re-entry.
The handling of CARP needs to be revisited architecturally. The M_PROMISC
flag may potentially be demoted to a link-layer flag only as it is in
NetBSD, where the idea originated.

This change is simlar to the change of PRIV_VFS_MOUNT in previous revision.
