History
Bruce M Simpson d565e5f206 In if_freemulti(), relax the paranoid KASSERT() on ifma->ifma_protospec. 
This KASSERT() existed as a sanity check that upper layers in the network
stack (e.g. inet, inet6) had released their reference to the underlying
driver's multicast memberships (ifmultiaddr{}). However it assumes the
lifecycle of the driver membership corresponds to the lifecycle of the
network layer membership.

In the submitter's case, ieee80211_ioctl_updatemulti() attempts to
reprogram the (parent, physical) ifnet{} memberships in response
to a change in membership on the (child, virtual) VAP ifnet, using
a batched update mechanism. These updates happen independently from
the network layer, causing a "false negative" assertion failure.

There are possibly other use cases where this KASSERT() may be triggered
by other networking stack activity (e.g. where a nesting relationship
exists between multiple ifnet{} instances). This suggests that further
review of FreeBSD's approach to nested ifnet relationships is needed.
