Description Alexander Bokovoy 2004-03-27 15:42:03 MSK

When interface link is down, it makes no sense to initiate DHCP or ZCIP
discovery which may take long time. As link is known to be down (via MII or
Ethtool) prior to discovery start, we can avoid boot delay by quering link
status before initiating the discovery. It gives better response time for user
especially with laptops which have both ethernet and WiFi links but using only
one of them for the moment.

Patch is attached. It uses /sbin/ifstatus from ifplugd package (if installed) to
report link status. It reports 'link down' only if ifstatus says so. Otherwise
it reports that link is up and discovery mode should start. Doing so we avoid
possible problems with old hardware or drivers which do not support either MII
or Ethtool interfaces as /sbin/ifstatus checks all available APIs.

Automatic Link detection for dynamic address assignments mode

Depends on ifplugd package (if installed). No change in behaviour compared to
current situation if ifplugd is absent.

Merged into upcoming 0.4.4.

Comment 3 Dmitry V. Levin 2004-03-28 17:04:55 MSD

Note that ifstatus was renamed to ifplugstatus: 
 
Tue Feb 10 2004: Version 0.22 released, changes include: 
rename ifstatus to ifplugstatus due to namespace collision, minor fixes.

Comment 4 Denis Ovsienko 2004-04-24 18:58:36 MSD

Пропущено в 0.4.4, но безвредно. Исправлено в 0.4.5.
