Bugzilla Bug 171447

If you set (for example) "random-samekind" as macchanger option in
/etc/conf.d/net for an Intel 3945ABG network interface, the network will not
start up properly.

A workaround is to add "sleep 3" after the macchanger command in
/lib/rcscripts/net/macchanger.sh:

        fi

                return 1


I assume there must be a better solution...

Reproducible: Always

Steps to Reproduce:
0. Use a Intel 3945ABG card as eth1 and have net-wireless/ipw3945,
net-wireless/ipw3945d, and net-wireless/ipw3945-ucode installed.
1. Set 'mac_eth1="random-samekind"' in /etc/conf.d/net.
2. Kill ipw3945d, remove its pid file, remove the ipw3945, ieee80211, and
ieee80211_crypt module.
3. Run 'modprobe ipw3945'. This will implicitly execute '/etc/init.d/ipw3945d
start' with current versions of ipw3945d (1.7.22-r4) after the module has been
loaded.
4. Run '/etc/init.d/net.eth1 start'.
Actual Results:  
/etc/init.d/net.eth1 fails, because iwconfig is run before the MAC change has
been successfully completed (I think; somebody should check and confirm that).

Expected Results:  
/etc/init.d/net.eth1 start should not fail; the script should wait until
ipw3945d has changed the MAC address of the network adapter before trying to
run iwconfig.

Versions used:
sys-apps/baselayout-1.12.9
net-wireless/ipw3945-1.2.0
net-wireless/ipw3945-ucode-1.14.2
net-wireless/ipw3945d-1.7.22-r4

You put a sleep between the mac variable being set and being tested - in other
words it does nothing.

I put the sleep *after macchanger is run*. That's what's important. You could
also move the sleep further down right before the return, I assume.

It does not do nothing: it pauses execution of the network scripts. Without the
sleep, the problem arises; with the sleep command, it doesn't.

I think ipw3945d needs some time to set the mac address on the card.

Adding sleeps for buggy drivers suck. Fix the driver :)

It sucks, yes .. but in this case, it's the only way to get the retarded thing
working.

This should be fixed w/ 1.2.2 (which contains a note about adding the preup
hook to /etc/conf.d/net as suggested by Momsen in bug 177869 comment0).
