dnl include <sys/ioccom.h>, and we were to drop support for older
dnl releases without that fix, so that pcap-bpf.c doesn't need to
dnl include <sys/ioccom.h>, the test program in "AC_LBL_FIXINCLUDES"

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