Re: panic: syncache: mbuf too small

Why not just allocate an mbuf cluster if the driver requires a huge
amount of space for L2 headers?  Or is it that we want to avoid the
extra branch in the syncache path?

Obviously a second allocation isn't ideal from a perf standpoint but
if only weird WiFi drivers feel that pain I don't think it's that big
of a deal, but perhaps I'm misunderstanding something.
