Subject: 2.6.34-rc1 regression: rmmod hangs on modules which interfaces have
 ipv6 address

Steps to reproduce:
1. Load driver
2. Bring interfaces up with IPv6 address 
3. rmmod the driver

rmmod fails with "waiting for device to become free. Usage count=1"

Bisecting turned up this patch:
http://git.kernel.org/?p=linux/kernel/git/davem/net-next-2.6.git;a=commitdiff;h=3e81c6da39a265e11ef48f52bd15bf7ca0068c75

Although I can't confirm this since without it I am not able to assign IPv6 addresses. So it could be caused by whatever this commit is trying to fix.

Thanks,
Emil--
