1735dnl Documentation/networking/packet_mmap.txt, is not 32/64-bit compatible before
1736dnl version 2.6.27. A 32-bit kernel requires a 32-bit userland, and likewise for
1737dnl 64-bit. The effect of this is that a 32-bit libpcap binary will not run
1738dnl correctly on a 64-bit kernel (the binary will use the wrong offsets into a
1739dnl kernel struct). This problem was solved in Linux 2.6.27. Use
1740dnl --disable-packet-ring whenever a 32-bit application must run on a 64-bit
1741dnl target host, and either the build host or the target host run Linux 2.6.26
1742dnl or earlier.
