sys/sys : mbuf.h
Log message:
Declare struct m_hdr as __aligned(8). This forces the compiler to pad out to
the next 8-byte boundary. This avoids introducing additional padding
between struct m_hdr and union M_dat in struct mbuf when we add a 64-bit
timestamp in struct pkthdr, which would lead to a miscalculation of MLEN and
panics on 32-bit architectures. Note that using __aligned(sizeof(int64_t))
here would make the compiler crash!
Put back the packet timestamp now that it is (hopefully) safe to do so.
