[netdrivers] Updated mii-diag.c v2.09 9/06/2003

[Donald Becker]

[[ I suggst distributions install 'mii-diag' with the name 'netif-config' ]]

Added mii-diag.8, a manual page for 'mii-diag'.

mii-diag.c:v2.09 9/06/2003 Donald Becker (becker@scyld.com)

Added '--monitor' option to allow scripting link beat changes.

This option is similar to --watch, but with lower overhead and simplifed
output.  It polls the interface only once a second and the output format
is a single line per link change with three fixed words
  <unknown|down||negotiating|up> <STATUS> <PARTNER-CAP>
  Example output:  mii-diag --monitor eth0
	down         0x7809 0x0000
	negotiating  0x7829 0x45e1
	up           0x782d 0x45e1
	down         0x7809 0x0000

This may be used as
  mii-diag --monitor eth0 | while read linkstatus bmsr linkpar; do
     case $linkstatus in
        up)   ifup eth0 ;;
        down) ifdown eth0 ;;
     esac
   done

Note that it may be useful to add the following to /etc/sysconfig/network
DHCPCDARGS="-t 3"

Other changes in this version are
   Added to the usage message.
   Corrected the exit(-1) calls to exit with a positive value.
   Use 'weak' function declarations to work even if libmii is not linked.
