No, it just about has to be a bug -- either in the mbuf allocator, the
driver, or the NIC hardware. M_PKTHDR is a flag in the mbuf header,
an area that isn't touched by packet data. The driver allocates
all of its receive mbufs with the M_PKTHDR flag set. There's no
legitimate way for the flag to get cleared, and nothing coming in on
the wire should be able to cause it to be cleared.
I mean a bug in if_bge.c - there are a lot of ways that this could
happen - not calling M_GETHDR, mis-calling m_pullup etc.
